All virtual machines on my ESX host off power at the same time

Hi all

Recently I attend the interview. a guy asked me this question

< police = "Times New Roman, serif" >all virtual machines on my power off ESX at the same time host < / police >< / police >?

What was the cause of the highest of the error, how to troubleshoot the error.please me.anybody guide to address this problem?

Thanks

Surya

If all the virtual machines if lower at the same time, my bet would be VMware HA. Just for fun, build it inside your head:

(1) 8 ESX nodes, all service consoles connected to a unique management switch.

(2) now to create a cluster of these nodes, put all your virtual machines in there and activate HA, choose ' host isolation response: power off.

(3) draw power from your management switch. HA on each host will deduct that the host is isolated-> turn off all the virtual machines.

Each host will think the same thing, and hop find you with all virtual machines down to the time in the whole of the cluster. Have seen this one several times when people go and upgrade their management switches in the evening ("hey, it's only management").

  • ESX as a virtual machine on an ESX host

    Currently, I am installing ESX as a virtual machine on an ESX host. I have a couple of hosts potentially put this VM: two 4.0 in the course of execution, one running 4.1. I would like to run this VM on the host running 4.1, and the virtual machine must run 4.0. Thanks to my documentation and research of compatibility, I found that it is not supported as an operating system to run in a virtual machine under ESX ESX, but it's for the workstation and fusion. I read on some blogs that ESX install as a virtual machine on an ESX host is possible (at least on older versions), but comes with a few problems, which have no workaround. I found (external) positions regarding do all this with the 4.0, but my preference would be to do with 4.1 on the host and 4.0 on the virtual computer. I can't find something to do with 4.1, which is not surprising given that the upgrade became available less than two weeks ago. Does anyone tried it yet? Is there anything, you have found or recommend as I approach to do this? (I read that the virtual computer must be configured as a computer virtual running RHEL 5 with 2 GB of RAM http://when all this is done with version 4.0, but I was not able to find much more.) Thanks in advance for any help and suggestions!

    Hello

    Yes, I tried last week and it worked for me. You are on the right track, we must select RHEL 5 64-bit as OS and assign the 2 GB of ram, and in addition to sound, you will need to use E1000 NICs for the installation to complete.

    FYI, this configuration is not taken in charge/tested/certified by VMware.

    Hope this information helps

  • List of virtual machines on an ESX host

    Is there a method in the sdk that lists all the virtual machines on an esx host?

    Simply get a reference to a HostSystem and it has an array property called vm http://www.vmware.com/support/developer/vc-sdk/visdk400pubs/ReferenceGuide/vim.HostSystem.html that gives you a reference to a matrix to all virtual machines on this particular host.

    Here is a sample Perl script that shows how to retrieve all the virtual machines for a specific host and certain attributes of the VM: getAllVMGuestHostname.pl

  • Get the list of virtual machines on an ESX host specific and dumping of .csv in a specific format

    I have problems to find a way to get a list of virtual machines on an ESX host specific and then he dumped to a .csv in the following format

    I use the get-vmhost esxhostname | Get - vm

    but everyhting else after, it is where I am lost...  I think the closest I had been posting the output with a goofy header and format 'vm1, vm2, vm3 "...

    name

    computer 1 name

    computer 2 name

    name of the machine 3

    to use for later use.  Any help would be appreciated.

    You must use the Select-Object cmdlet to specify more precisely the properties you want.

    The Export-Csv doesn't know how to manage the virtual computer object.

    Something like that

    Get-vmhost esxhostname | Get - vm | Select name. Export Csv.\report.csv - NoTypeInformation - UseCulture

  • Disable vmotion for 1 virtual machine in an ESX host

    Hello

    We have an ESX environment that is configured with vMotion.

    As a result, I've seen VMs from one ESX to another very frequently.

    Among these virtual machines, I have a very critical virtual machine, I want to move to any other host ESX.

    Y at - it an option that I can use to disable VMotion only for this particular virtual machine of mine (in order to keep constant on the ESX on which it is right now) and allow the other virtual machines to continue.

    Appreciate your help.

    Thanks in advance

    I guess that your VMS migrate between ESX servers because configuration automated DRS ESX cluster level. You can replace it for a specific virtual machine. Cluster of right click Select-> "Settings"-> click on options of the Virtual Machine under VMware DRS,. On the right, make sure 'Enable the levels of automation individuak virtual machine' is checked. You can see VMs list below. Select the virtual machine that you want to replace and change the level of automation for people with reduced mobility

  • Can I use an antivirus on each of my hosts and guests at the same time when running a virtual environment on my PC?

    I have Windows 7 running on my main computer at present and that you have a virtual environment installed as an operating system on this computer very.

    I would like to know if I am able to run an internet security on my pc (Windows 7) host program and other internet security on my guest in my virtual environment operating system (pc windows 8)... at the same time.

    I ask this question because... I installed my OS of windows 8 in a virtual environment running inside my Windows 7 OS in order to familiarize yourself with the features of windows 8 and to test the compliance of windows 8 with various hardware components I use... to satisfy my curiosity before I migrate eventually completely to windows 8.

    Part of my tests would involve various software including Internet security applications.

    So the question is... I was able to save my virtual environment with an Internet security program, while having an Internet security program running in the host computer?

    PS my environments hosts and guests are not put networked with the exception of the common external drives and dvd burners. The plan being that the Internet security on my host computer program will have my analysis excluded virtual environment.

    Yes

    The systems are completely separated from each other, will not affect the different AntiVirus on another product.

    If you decide to test another Internet security program don't forget to completely remove the old version on the virtual machine

  • Get the list of virtual machines on an ESX host specific AND of a specific folder...

    I'm trying to get a list of the virtual machines running on an ESX host specific, but also are located in a specific folder.

    Any thoughts?
    Thank you!

    VMHost and folder use the Get-VM-setting position. You must select either using the Where-Object cmdlet filter. For example:

    Get-VMHost $esx_hostname |
    Get-VM |
    Where-Object {$_.Folder.Name -eq $folder_name}
    
  • What is the interval of time between the virtual machine Linux and ESXi host synchronization?

    I have ESX5.0 with a centos6 installed on this linux virtual machine.

    After the installation of vmware for Linux virtual machine tools, I activated the time synchronization between the virtual machine linux and ESXi host through vmware-toolbox-cmd.

    I wonder what is the interval of time between the virtual machine linux and ESXi host synchronization? If I quickly time OS system, when the OS system time will sync back to the ESXi host?

    According to http://www.vmware.com/files/pdf/techpaper/Timekeeping-In-VirtualMachines.pdf:

    By default, the demon checks the guest only once per minute operating system clock.

    However, depending on whether the guest is behind or in front of the result is different. So, please read the section "periodic synchronization" (at least) in the document mentioned above.

  • Get-file provides an account of all virtual machines in the folder structure.

    Hi all

    Tried a few searches in the community, but impossible to find exactly what I was looking for.  We have a configuration folder structure in vCenter.  We have some companies that we bought over time and we set up a folder, separate them with a top-level folder and folders nested for different types of virtual machine below, something like:

    CompanyX

    -Mail servers

    -Web servers

    -DB servers

    For the purposes of internal billing, asked me to get a count of all virtual machines for each company.  I can get the count for virtual machines directly in the "CompanyX" folder, but it does not include virtual machines in subfolders.  This is the script I used so far:

    Write-Output "VM enumeration for CompanyX VMware environment Total: $((Get-dossier 'CompanyX' |)). "(Get-VM) .count) | out-file "D:\ScriptResults\CompanyX.txt" - append

    As I said, that works very well for the virtual machines in the head in the parent folder, but it does not go down to the next layer.  Is there a way to get folder do that?

    I am a novice PowerShell/PowerCLI, so forgive me if I'm missing something obvious.

    Thank you

    Bob

    Hi Bob,

    I don't know if it was different in previous versions, but in the latest PowerCLI version 4.1 U1 if you

    Get-file "CompanyX" | Get - VM

    It will retrieve the VM in the top folder and all subfolders. You can easily check this with:

    Get-file "CompanyX" | Get - VM | Select-Object - Property Name, folder

    If you only want the virtual machine in the top folder you can use:

    Get-file "CompanyX" - NoRecursion. Get - VM

    The following script will get the VM number for all companies and write the result to a .csv file.

    $ExcludeFolders = "Discovered virtual machine","other folder to exclude"
    Get-Folder vm | Get-Folder -NoRecursion | `
    Where-Object {$ExcludeFolders -notcontains $_.Name } | `
    ForEach-Object {
      $Folder = $_
      $Report = "" | Select-Object -Property Company,"Number of VM's"
      $Report.Company = $Folder.Name
      $Report."Number of VM's" = ($Folder | Get-VM | Measure-Object).Count
      $Report
    } | Export-Csv -Path CompanyVMsCount.csv -NoTypeInformation -UseCulture 
    

    If there is high records of the page you want to exclude from the list you can add them to the $ExcludeFolders variable in the first line of the script. The second line of the script gets all the 'vm' top of the folders page. The third line filter unwanted records. A few lines create the output objects. And the last line written objects in a .csv file.

    I added the Measure-Object cmdlet for the ($Folder |) Get - VM | Measure - Object). Account because otherwise you will get an error if the number is 0 or 1.

  • ESX host, as well as the NFS server?

    Hi all and thanks in advance for any help.

    I want to know if it is possible to turn essential a LUN on a host in a NFS for another host.

    The vmkernel will allow me to share a hdd connected locally on a host to another host?

    For example.  ESX1 has a 1 TB drive, ESX 2 boasts a record of 400GO.  I want to share the drive between machines as data warehouses.

    The hosts are on the same domain and a fairly typical storage facility.

    I want to leave the VI client manage sharing, but I need a mounting point for training and one for access to hosts.

    Setup NFS on both ESX hosts will cause problems?

    Thanks in advance, once again.

    I really need to know if I can just use NFS on each ESX and run it at the same time as VMware.

    The short answer is no.  ESX was not designed to be an NFS server, should not be.  Thus, there MAY be servers NFS that will work, but they have compiled and built on the ESX host, which is beyond the scope of this thread, so let's say no. NFS on ESX host.

  • Close all virtual machines on ESXi

    Hello

    I'm new in the administration of vSphere. I would like to raise our ESXi servers due to updates, but I've read that you shut down all virtual machines that are on it. You have something better to do then close VMs one? I expect a powershell script, but I have found none so far.

    Thank you

    Kralijir, you can do it from the console GUI.

    In the left pane, select the ESX host.

    In the right pane, click the tab "virtual machines". Now, you can select block all virtual machines here and simply right-clicking them stop all, or make other changes in bulk.

    Some changes via selection bulk require all virtual machines to be in the same State; Turned off the power, power, etc.

  • Setting Options such as Hotplug for all virtual machines

    Hello!

    I have about 5 esxi hosts 5 and about 50 virtual machines

    Unfortunately I forgot to select some options like activate the plug-in memory and cpu hot

    I have 2 questions

    1 can I do this without turning off the machine

    2. How do I make a few options like this (or for example another option as vmtools update during the feeding cycle) for all virtual machines in my environment

    It's too much time to go to all virtual machines and turn them off and turn on these options

    Thank you very much

    These features must be enabled before the virtual machine is running.  So, you will need to turn them off and then use something like powercli to enable the features and turn them back on.

    Here is an example on how to do it with powercli: http://ict-freak.nl/2009/10/05/powercli-enabledisable-the-vm-hot-add-features/

  • Unable to migrate virtual machines from one ESX to another in a cluster

    I have 7 ESX in a cluster... 2 ESX are unable to migrate virtual machines into and out of the host... When we try to perform a manual migration, it displays the following error...

    Impossible to pass. Host CPU is not compatible with the requirements of the Virtual Machine to CPUID level 0 x 80000001 registry "edx" host bits: 1110:1111:1101:0011:1111:1011:1111:1111 required: 11 x 0:1 x 11: 1100:0011:1111:x 0x1: 1111:1111 inconsistency detected for these characteristics: * NX/XD (data execution protection). If the Virtual Machine does not have this feature, power off the virtual machine and delete the requirement of NX/XD by changing the settings of the virtual machine (advanced options).

    Looks like 2 of the 7 ESX has disabled NX/XD (or could be activated I don't know which) in the BIOS of the Server - VMware allows you to maske this characteristic shape the VM so it can vmotion between these hosts - initially put there where the NX/XD bit became more popular in order to allow users to migrate between these hosts with different parameters CPU-
