linux ht, 2 proc, cpu affinit

Felipe Olivaes — Thu, 03 Nov 2011 11:13:15 +0000

In linux Servers there is always difficulty in finding the server is multi-processor, multi-core or Hyperthreading is enabled or not.

Let’s check this, but first keep in mind the following points:

1) Physical ID = Number assigned to each Processor on MotherBoard

2) Sibling ID = Number of logical processor provided by each Physical Processor

3) Core ID = Number of core in the Physical Processor

Note: If core Id is equal to sibling ID it means there is no Hyperthreading

If sibling ID is double that of core ID it supports Hyperthreading

Command: cat /proc/cpuinfo

Case 1:

Single-processor, Single-core, HT

processor 0 1
physical id 0 0
siblings 2 2
core id 0 0
cpu cores 1 1

The cpu cores value is “1″, so this system uses single-core processors.
The cpu cores value does not match the siblings value, so this system has hyperthreading.
There is one physical id listed, so this is a single-processor, single-core system with hyperthreading.

Case 2:

Single-processor, Dual-core, non-HT

processor 0 1
physical id 0 0
siblings 2 2
core id 0 1
cpu cores 2 2

The cpu cores value is “2″ so the system uses dual-core processors.
The cpu cores value matches the siblings value, so this system does not have hyperthreading.
There is one physical id listed, so this is a single-processor, dual-core system without hyperthreading.

Case 3:

Dual-processor, Dual-core, HT

processor 0 1 2 3 4 5 6 7
physical id 0 0 0 0 1 1 1 1
siblings 4 4 4 4 4 4 4 4
core id 0 0 1 1 0 0 1 1
cpu cores 2 2 2 2 2 2 2 2

The cpu cores value is “2″ so this system uses dual-core processors.
The cpu cores value does not match the siblings value, so this system has hyperthreading.
There are two physical IDs listed, so this is a dual-processor, dual-core machine with hyperthreading

Case 4:

Dual-processor, Quad-core, non-HT

processor 0 1 2 3 4 5 6 7
physical id 0 1 0 1 0 1 0 1
siblings 4 4 4 4 4 4 4 4
core id 0 0 1 1 2 2 3 3
cpu cores 4 4 4 4 4 4 4 4

The cpu cores value is “4″, so the system uses quad-core processors.
The cpu cores value matches the siblings value, so this system does not have hyperthreading.
There are two physical IDs listed, so this is a dual-processor, quad-core system without hyperthreading

Case 5:

Dual-processor, Quad-core, HT

processor 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
physical id 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1
siblings 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8
core id 0 0 1 1 2 2 3 3 0 0 1 1 2 2 3 3
cpu cores 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4

The cpu cores value is “4″, so the system uses quad-core processors.
The cpu cores value does not match the siblings value, so this system has hyperthreading.
There are two physical IDs listed, so this is a dual-processor, quad-core system with hyperthreading.

Cloning virtual machine on vmware esx using vmware-cmd

Below are the steps:

1. List down all the virtual machines that you have

# /usr/bin/vmware-cmd -l
/vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-1/server-1.vmx
/vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-2/server-2.vmx
/vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-3/server-3.vmx

2. Shutdown the machine that you are going to clone. Let say the machine is server-1

# /usr/bin/vmware-cmd /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-1/server-1.vmx stop

3. Use hard stop if you cannot stop it using above command

# /usr/bin/vmware-cmd /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-1/server-1.vmx stop hard

4. Make sure the vm is shutdown by viewing the state

# /usr/bin/vmware-cmd /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-1/server-1.vmx getstate

5. Copy the whole directory

# cp /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-1/ /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/newserver/

6. Once done, rename all the files to new name

# rename server-1 newserver /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/newserver/*

7. Change all occurrence of “server-1″ to “newserver” in .vmx, .vmdk and .vmxf

# cd /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/newserver/
# sed -i ‘s/server-1/newserver/g’ {newserver.vmdk,newserver.vmx,newserver.vmxf}

8. Edit newserver.vmx file and remove below lines

ethernet0.generatedAddress = “…..”
ethernet0.generatedAddressOffset = “…..”
uuid.location = “…..”
uuid.bios = “…..”

9. Add below line to newserver.vmx

uuid.action = “keep”

10. Register your newly cloned virtual machine. Please use the full path to register as below

# vmware-cmd -s register /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/newserver/newserver.vmx

11. Start your new vm after registration.

# /usr/bin/vmware-cmd /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/newserver/newserver.vmx start

vmware tools centos 5.5

Felipe Olivaes — Wed, 16 Feb 2011 13:22:34 +0000

from: http://fusion.infofabrics.com/Home/enviornment-infrastructure/personal-cloud-using-esxi

VMWare can exploit yum repository.

1. Import public key for yum repository. Execute this as root

# rpm –import http://packages.vmware.com/tools/VMWARE-PACKAGING-GPG-KEY.pub

2. CentOS stores yum repository definition in /etc/yum.repos.d
Create a file named, vmtools.repo and populate it with following contents
[vmware-tools]
name=VMware Tools for CentOS $releasever – $basearch
baseurl=http://packages.vmware.com/tools/esx/4.0/rhel5/x86_64
enabled=1
gpgcheck=1

In the above example, I’ve used baseurl with “4.0″ as ESXi version & x86_64 for 64 bit CentOS. This can be different for you.

3. Run yum install command to install VMWare tools on your CentOS Linux server.
# yum install vmtools

You should see installation log on your screen at attached on this page “yum_vmware-tools.install.log”, with one prompt for vmware package installation.

4. Restart CentOS linux server.

GOOD NEWS, post CentOS restart if you go to vSphere vmserver instance -> console you don’t have to press Ctrl+Alt every time you want to switch between Linux console & Windows OS . And it’s fast too.
