Just got back from the VMWare Fast Track training and I am feeling virtually ready for the VCP exam. While I was on site I took a lot of notes and did a lot of surfing to find information about VMWare VCP and VMWare resources.

VMWARE Infrastructure 3 Fast Track 3:

If you see any command line – that is not testable. From a test perspective it is not on the test. The last four modules are not testable.

Four food groups:

Four things for testing:

Installation of ESX and Virtual Center and the plugins

Perform configuration of networking, storage, datastores, and services, using both the GUI and command-line utilities.

VMware Concepts

VMKernal / Hypervisor
A hypervisor translates something from physical to virtual and back.

Four files of interest.

VMX-Config – Hardware based attributes, virtual hardware configuration file.
VMDK-Virtual Disk – This is the actual virtual disk- Virtual machines look at Virtual Disks as a local SCSI file (this is on the test) It always thinks it has local SCSI storage. IMPORTANT….
NVRAM- BIOS of the Virtual Machine
VMWare Log- VMWARE.LOG

(Encapsulation)

The service console is based on red hat enterprise 3 baseline 10. Gives us ssh, and other services.

ESX Server Installation

ESX Requirements:

Embedded for ESX – In the DMZ good for opsec.
Processor Two 1500 or Higher x86 based processors
Memory 1- 256 GB supported
Networking – 4 or More Ethernet Interfaces
Supports up to 10 GB
Supports booting from IDE/ATA disk drive or a (SATA) disk drive provided they are booted through supported controllers.
SCSI Drives
Storage networks

Note: For security and performance, use separate interfaces for the service console and the virtual machines.

Disk Storage

A SCSI adapter, Fiber Channel adapter, iSCSI adapter or internal RAID controller.
A SCSI disk, FIBER Channel LUN, iSCSI disk or RAID LUN with unpartioned space.

*infiniband? http://en.wikipedia.org/wiki/InfiniBand 10 GB

Note: The reason why you increase memory in the service console is due to agents.

^{The service console by defaults gets 272mb You can only change this from the virtual infrastructure client after ESX is installed and then you will need to reboot.

It can max out at 800 MB

You can increase swap to 1600MB}

‘how to install and configure NTP on VMware ESX host’

1. SSH on to VMware ESX host service console as the root user
2. Make a backup copy of existing files.
[root@esxhost]#cp /etc/ntp.conf /etc/ntp.conf.orig
[root@esxhost]#cp /etc/ntp/step-tickers etc/ntp/step-tickers.orig

3. Edit /etc/ntp.conf
[root@esxhost]#vi /etc/ntp.conf
#Insert the following details as example below:
restrict ntp1.planetmy.com kod nomodify notrap server
restrict ntp2.planetmy.com kod nomodify notrap server
server ntp1.planetmy.com
server ntp2.planetmy.com
driftfile /var/lib/ntp/drift
authenticate yes

Please refer to here for a full description of these access control commands. The driftfile line indicates the name of the file where the value for the system’s clock drift (frequency error) is stored. For a more complete definition of driftfile, see here.

4. Edit /etc/ntp/step-tickers
[root@esxhost]#vi /etc/ntp/step-tickers
#Insert the following ntp server as example below:
ntp1.planetmy.com
ntp1.planetmy.com

5. Edit /etc/hosts
[root@esxhost]#vi /etc/hosts
#Insert the following details as example below:
10.10.10.1 ntp1.planetmy.com ntp1
10.10.10.2 ntp2.planetmy.com ntp2

#Adding this list of NTP servers minimizes the impact of DNS lookup failures during NTP synchronization.

6. Firewall – opens the appropriate ports and enables the NTP daemon to talk with the external server.
[root@esxhost]#esxcfg-firewall –enableService ntpClient

7. Restarting and Monitoring the NTP Service
#To restart the service now, run:
[root@esxhost]#service ntpd restart

#To enable the NTP daemon to autostart when the server is rebooted, run:
[root@esxhost]#chkconfig ntpd on

#Set the local hardware clock to the NTP synchronized local system time, run:
[root@esxhost]#hwclock –systohc

#Monitor the NTP service
#See the offset (in seconds) between the local clock and the source clock, run:
[root@esxhost]#ntpdate -q NTP_time_server_name_or_ip_address

#To watch the status of the ntpd process, run:
[root@esxhost]#watch “ntpq -p”
#Press Ctrl-c to stop watching the process.

#start time synchronization without rebooting, run:
[root@esxhost]#/etc/rc.d/init.d/ntpd start
#The time drift corrects after a while.

#please wait few minutes andlist the current status
[root@esxhost]#ntpq -p

8. Manually synchronization
[root@esxhost]#/etc/init.d/ntpd stop
[root@esxhost]#/etc/init.d/ntpd status
ntpd is stopped
[root@esxhost]#ntpdate -u ntp1.planetmy.com
17 Jul 20:20:12 ntpdate[22944]: step time server 10.10.10.1 offset -8671.09148 sec

9. Adjust Time Zone
[root@esxhost]#cp /usr/share/zoneinfo/Asia/Kuala_Lumpur /etc/localtime
[root@esxhost]#date

Networking:

*IMPORTANT* What are the basics behind networking in the ESX server?

Virtual switch

Each Virtual Nic has its own mac address
Up to 1016 Ports per Virtual Switch

VMkernal is the heart of the system and has all the device drivers to bridge the virtual hardware and the physical hardware.

VMKernal network traffic

ISCSI – ISCSI uses VMKernal Ports.
VMotion
NAS storage

NicTeaming when you bond or put two teams together.

VM Network
If you want to connect a virtual machine to a virtual switch you need to have a VMport group.

Service Console is VSWIF0

There are thee connection types for virtual switches

Virtual machine, Vmkernel, Service console

VLAN:

Virtual Subnets
“tag” packets with a VLAN ID
0<ID<4096
IEEE 8021QVLan Tagging
Assigns VLans per port group
Requires trunking

The “switchport trunk native vlan 4094″ command is what fixes the problem I had last time I worked with ESX Server and VLAN trunks; namely, that most switches don’t tag traffic from the native VLAN across a VLAN trunk. By setting the native VLAN for the trunk to something other than VLAN 1 (the default native VLAN), we essentially force the switch to tag all traffic across the trunk. This allows ESX Server to handle VMs that are assigned to the native VLAN as well as other VLANs.

On the ESX Server side, we just need to edit the vSwitch and create a new port group. In the port group, specify the VLAN ID that matches the VLAN ID from the physical switch. After the new port group has been assigned, you can place your VMs on that new port group (VLAN) and—assuming you have a router somewhere to route between the VLANs—you should have full connectivity to your newly segregated virtual machines.

Trunking

VLANs are local to each switch’s database, and VLAN information is not passed between switches.
Trunk links provide VLAN identification for frames traveling between switches.
Cisco switches have two Ethernet trunking mechanisms: ISL and IEEE 802.1Q.
Certain types of switches can negotiate trunk links.
Trunks carry traffic from all VLANs to and from the switch by default but can be configured to carry only specified VLAN traffic.
Trunk links must be configured to allow trunking on each end of the link.

Enabling Trunking

Trunk links are required to pass VLAN information between switches. A port on a Cisco switch is either an access port or a trunk port. Access ports belong to a single VLAN and do not provide any identifying marks on the frames that are passed between switches. Access ports also carry traffic that comes from only the VLAN assigned to the port. A trunk port is by default a member of all the VLANs that exist on the switch and carry traffic for all those VLANs between the switches. To distinguish between the traffic flows, a trunk port must mark the frames with special tags as they pass between the switches. Trunking is a function that must be enabled on both sides of a link. If two switches are connected together, for example, both switch ports must be configured for trunking, and they must both be configured with the same tagging mechanism (ISL or 802.1Q).

Preferred way- Run physical connection to the trunk port and tag these VLans on the virtual switch.

Load balancing method:

Vswitch port based Page 124 All the I/O goes one specific path. Each comes on and generates a port and then chooses a nic for that. If you are configured for the port based approach.

Mac Based is similar it uses the mac address as opposed to the port number. All the I/O goes one specific path.

IP-Based- takes IP from the client and bases traffic on this. This has to be supported by a physical switch. Etherchannel 802.3ad

EtherChannel is a port trunking (link aggregation is Cisco‘s term) technology used primarily on Cisco switches. It allows grouping several physical Ethernet links to create one logical Ethernet link for the purpose of providing fault-tolerance and high-speed links between switches, routers and servers. An EtherChannel can be created from between two and eight active Fast Ethernet, Gigabit Ethernet or 10 Gigabit Ethernet ports, with an additional one to eight inactive (failover) ports which become active as the other active ports fail. EtherChannel is primarily used in the backbone network, but can also be used to connect end user machines. A former limitation of EtherChannel was that all the physical ports in the aggregation group must reside on the same switch. The SMLT protocol removes this limitation by allowing the physical ports to be split between two switches. Cisco’s Virtual Switching System allows the creation of a Multichassis Etherchannel (MEC) allowing ports to be aggregated towards different physical chassis that conform a single “virtual switch” entity.

Know Lessons 1 and 5 to pass the VCP.

Service Console is esxcfg-firewall

When we use that command it puts a lock on the main config file and safely changes the firewall rules.

Storage:

Fiber Channel Storage Area Networks-

Fiber Channel high speed transport protocol used for SANS. Uses encapsulated SCSI. Uses “Fiber Channel” is the protocol.

LUN is a “logical disk”

Fiber Channel SAN is the network and the disk array. Disk array is configured by the “storage administrator”

Fiber access ports are called Storage Processors (storage access ports).

VMWare recommends 16 LUNS per host.

256 LUNS in ESX
128 scanned on install
rescan once installed.

When you have 128 GB of RAM you have to change force 64 bit recognition because the service console only sees 64GB.

esxcfg-advcfg configuration recommended by the vendor.

http://www.nsa.gov/ia/_files/support/I733-009R-2008.pdf

ISCSI SAN Storage

Hardware and Software Inititated:

What is ISCSI?

It is block level access in an IP packet.
Similar to mapping SCSI over Fiber Channel.

Initiators are iscsi hba. You need a physical HBA card to boot from ISCSI to ESX.
ISCSI LUNS are the same as Fiber Channel.

RDM Raw device mapping Virtual Machines can access a raw ISCSI LUN. This is a NON VMFS volume.

Allow VMotion migration of a VM whose files reside on an ISCSI LUN. VMotion does not care if you are using ISCSI or FIBER.

More than one HBA for redundancy. ** Fault tolerance. The VMKernal (VMWare- has a software inititator.) The software initiator uses regular physical NICs.

VMHBA32-Software Inititator is what will show up as the software ISCSI. It may not be exactly 32 it may be something in the 30 series.

Addressing in an ISCSI SAN is a little different we have a DNS derivitive naming convention that is NOT DNS but something like it. You can use EUI or IQN naming convention. VMWare chose to use IQN. If you were to build the IQN yourself the name shouldn’t matter but to follow the naming convention you want to use the data you registered your domain.

Storage processor is the “target”

For the software initiator (which is the VMKernal) it only uses SENDTARGETS only (on the test).

There is SENDTARGETS and STATIC that you can use with hardware ISCSI.

SENDTARGETS is SOFTWARE ONLY.

The only way to authenticate with iscsi is CHAP.
This is a ONE way relationship. The ESX Server logs into the storage device. It only logs into the storage array. IT IS ONE WAY (this is on the test).

They only support two hardware HBA’s Qlogic 4050 and 4060 series. What about the performance difference in a hardware solution as opposed to the software ISCSI. The sofware initiator is not a problem. There is not enough overhead to cause a problem. It is fine to do software using the cpu. Unless you are running the esx server over 80% utilized on CPU time.

The service console has to first
do discovery which is “sendtargets”
then it does CHAP with is the authentication.

Understand the five steps in order for the test *setup software initiated.

1: Networking setup- need two nics for redundancy and two ports one for the iscsi application and the other for the service console.

You need another service console port if it does not have access to the management network. AS LONG as you have access to the management network you don’t need another service console port.

2: Firewall- outgoing port 3260 needs to be configured to communicate with the iscsi appliance.

3:Configure the ISCSI software inititiator click configure and then click enabled. Then “Sendtargets” that is the discovery method.

4:DISCOVERY Choose a storage processor and enter the ip address of the iscsi device. click add then discover.

5: CHAP
Make sure that the ISCSI appliance will advertise all of the targets.

For scripted installations you will need to know how to add the commands on command line.

If the disc I/O is substantial ISCSI may not be a good solution unless you are using 10G or better.

VMFS came up with their own file system because of the VMDK file. The reason why is because a VMDK can grow up to 2 TB. It is possible to have large VMDK’s. File systems do not handle VMDK’s well so they came up with VMFS. You can store VMDK’s and Templates in the VMDK. Templates are VM’s that you baseline.

Maximum block size asks what is the largest virtual disk that you plan on building. If you are building something greater than 256GB you have to change the block size. That is the Max virtual disk size. – Testable.

You can span 32 VMFS Spans together which equals a 64TB SPAN

One path to any LUN at anytime is active. ONE PATH with fiber channel or storage. On the test.

• All privileges for all privilege groups, except permissions.

Resource settings:

How VM’s use and share the CPUs’ ?

VCPUS’s mapped to pCPUs
One pCPU to many vCPU’s
Ready Time – Bottleneck Indicators (When a cpu has to wait it is dealing with “ready time”)
Rebalanced Every 20 Milliseconds
Hyperthreading
VMs using multi-vCPU scheduled simultaneously

Service console always stays on CPU 0.

The standard approach is to build the server with one vCPU. If the end user needs more then and only then would you give them more.

Three user defined settings for CPU resource allocation:

CPU limit – Is the capacity of the hardware. You could slow it down but not speed it up because it is a physical limitation. If you limit a CPU that is the amount of time the CPU will get and that is IT.
CPU reservation – Reservation or guarantee of a certain amount of CPU time. When CPU contention occurs you can RESERVE the CPU time. A reservation could prevent other VM’s from loading or lock up CPU time.
CPU Shares – More shares means “this CPU will win more competitions for time more often.” Means Priority under contention. Systems could get a higher priority.

Memory:

Limit: The maximum amount of physical RAM that the VM can use by default. We can only LOWER the limit.
Reservation: A certain amount of RAM preallocated or reserved for the system.
Share: Will win more competitions once the priority is set.

.Vswp that is the swap file created for the VMachine. **** When the vm is powered off the swap file goes away.

Memorize VMotion requirements:

Migrating a VM with the following conditions produces an ERROR.
Migrating a VM with the following conditions produces a warning.

Storage VMotion-

Takes a snapshot of the guestOS because the OS is in a locked state, it moves the snapshot using VMotion and then it makes the changes and updates the guest OS.

It performs a VMmotion within the host.

Storage motion is a hot migration that you can use to move OS files with the OS is working.

http://lycos.dropcode.net/VMware/Documentations/vmworld2008/

Resource pools –

VMware DRS (Distributed Resource Scheduler) – Automatic load balancing.

DRS Clusters
A cluster is a set of hosts put together for DRS, HA or both.

32 Hosts per cluster.

Automation level

Manual- Makes recommendations to move a VM and it does this by a rating system.
Partially- when you power on a server it places it on the best suitable host (like round-robin) if the server is already on it will RECOMMEND a move for the VM.
Fully Automate- When you power on a vm it places the vm on the best host and then if the loads become unbalanced the vm’s will move automatically.

Migration threshold

Level 1 most conservative
Level 2 moderately conservative
Level 3 the default midpoint
Level 4 Moderately aggressive
Level 5 Aggressive

CPU balances the load every 20 millisecs.

Transparent Page Sharing

Identifies identical pages in VM’s memory and maps them to the same underlying page. If there is a straight line in a graph it is normailizing the page file.

****THE BALLON driver mechanism VMMEMCTL ****

Instead of going to the swap file right away the VM will try to go to a VM that is claiming RAM the VMKernal will try to reclaim that ram and redistribute it back to system for use. You need VMWare tools installed for this to work.

Balloning is more efficient than swapping and this is an indication of memory issues.

Worst case it uses the VMswap file.
The VMswap file is the same size as the ram configured for it.

CPU Ready shows if there is actual cpu contention.

High Availability:

A cluster can be 32 servers.

http://www.vmware.com/pdfg/vi3_301_201_mscs.pdf
MS Cluster in a box
Cluster across boxes
Physical to virtual clusters

This version of HA from VMWare is not zero downtime.
It is an automatic restart of the virtual machine.

AAM – EMC autostart manager. This gets installed on the ESX server. When you bring up the first five ESX host server they become 5 primary agents. All other past the first 5 become secondary agents.

How do you create HA accessibility?

Create a cluster then check the HA box.
There is a new section once you do that called VMWare HA. We can setup the cluster for how WE want it to run.

You can only reserver up to 4 full servers of full capacity.
Isolation response is another way of saying

Admission control

If you do not have enough resources it will not allow you to start virtual machines.
Allow virtual machines as long you can restart them.

Advanced Options:

HA Pool Cluster Settings

Restarting Priority on the cluster
High
Medium
Low

In Virtual Machine Options
and options for resource priority are on a per vm basis.

You start the high priority first then the mediums come up after.

What if a host finds itself ISOLATED?
You can chose if you want to power on or off the VM.
The heartbeat is only on the service console.

There are also numerous tips and scripts for locking down your virtual infrastructure in the VMware Community Forums (Start here: http://communities.vmware.com/message/941372).

So back to the question of second super user accounts: It seems that best practices are to create a second user account with sufficient access to the console, granting that user SUDO privledges, and then disabling the default root account.
To scan the virtual machines you need to install an agent.

1. Diane Greene wants to install ESX server on two IBM HS20 Blades. Each blade has two dual core CPU’s. How many ESX server processor licenses will be needed for this setup ?

2. Diane Greene wants to install ESX server on an old HP DL380 G1 that is in the office. It has dual 1gig processors, 1 gigabyte of RAM, 1 gig network connection and 146GB of internal disk space. Which hardware spec on this machine does not meet the minimum requirement ?

The Ram

The Disk Space

The Memory

The processor speed

3. Diane Greene is installing ESX server and keeps getting prompted to initialise the disks more than once. He knows that there is only one set of internal disks in the ESX server, so what could be the problem ?

There is a bug in the ESX server installation

He has not unplugged the SAN or correctly zoned the SAN before installing ESX

It is not prompting to initialise the disk, it is actually prompting for each partition

ESX is performing multiple initalisations to make sure the disk is totally clean before install

Disconnecting a host from the SAN is always the first thing that should be done before an ESX server is built. That is unless there is an immediate requirement to boot from SAN or access SAN resources straight away. In the latter case then correct SAN zoning should be applied before the build commences. This is on page 16 of the course manual in module 2 – install ESX server.

4. What tests should Diane Greene perform on his hardware before installing ESX server ?

He should run disk I/O tests and the cpu compatibility checker

He should test the memory for 72 hours and install a dummy operating system

He should test the memory for 72 hours and test install the media.

5. If Diane Greene builds an ESX server and does not have a virtual center installation how does he license the ESX server ?

Connect the virtual infrastructure client to the ESX server and upload a host based license

Connect the virtual infrastructure client to the ESX server and upload a server based license

The license key is entered during installation so it is already licensed

An ESX server that does not have access to virtualcenter or a license server needs to use a host based license. This is achieved by uploading a host based license through the Virtual Infrastructure client connected to the host.

6. Is it possible to connect more than one physical nic to a virtual switch ?

yes

vmmemctl = balloon driver & reclaims unused memory from the guest OS Provides least negative effect on performance of running VM’s

Memory Idle Tax specifies the idle memory tax rate as a percentage. A tax rate of 0 defines an allocation policy that ignores working sets and allocates memory based on shares. A high tax rate results in an allocation policy that allows idle memory to be reallocated away from virtual machines that are hoarding it. Default is 75 (Remember MemTax = 75)

Memory Tax prevents virtual machines from hoarding idle memory

Memory Virtualization does not provide contiguous physical memory

Swap is size between memory and reservation

Type is for resource pools Resource pools manage host memory and cpu

Recommendation: Use dedicated switch when using Software Initiators

VMWare Server 1.x does not support dynamic resource management

You can add hardware to virtual machines through Web Access

Increasing the memory shares for a virtual machines has no effect on the physical memory resources used for virtualization overhead

ESX uses short-lived SCSI reservations as part of its distributed locking protocol

LUN Masking is done on the host and storage processor

Server manages network and disk resources on a per-host basis

MRU is recommended policy for Active / Passive Fixed is recommended policy for Active / Active

Mem.ShareScanVM controls the rate at which the system scans memory to identify opportunities for sharing memory (default 50)

3 physical implmentation alternatives for SCSI devices .vmdk file stored on a VMFS volume Local SCSI device passed through directly Device mapping to a SAN LUN

MRU and Fixed are 2 possible storage multipathin policies

Affinity is ignored as a part of VMotion

Shares Value is the number of shares allocated to a Machine

VMKernel controls memory, physical processor, storage controllers, networking, keyboard / video / periphrials

3 pre-defined ESX Server Roles are Administrator, Read Only and No Access

A characteristic of a mapped SAN LUN set to Virtual Compatibility mode is to allow the virtual machines to use VMWare Snapshots

Max iSCSI targets is 64

The default number of ports for a vSwitch is 56 however it can be created with up to 1016 ports.

Check High CPU ready value for CPU performance problems
