  Sounds good the problem crept... FIR alarms... service VC services.msc reboot and see if it helps... If not we will have to examine the log files to see if there are errors.

• Unable to start the virtual machine after Migration - ESXi hosts

  Last night I wanted to move a virtual machine to a host of test to a production cluster.  All hosts (test and production) have shared access to the same LUN, so I usually am able to simply remove the virtual machines of the inventory in the test environment and add them to the production environment by accessing the .vmx on the data store file.  Two of the 3 hosts migrate perfectly and are running in the production environment.  However, the third server, while the migration starts.

  First he gave me errors that it was missing some files.  The only thing I did was different to rename the folder for the virtual machine on the data store.  It was called 'New Virtual Machine' for a reason, so I renamed it to "Antivirus."  However, something strange happened.  Instead of renaming the folder, it seems was created a new folder named "Antivirus" and the old folder 'New Virtual Machine' was still there.  In addition, the renamed folder 'Antivirus' had only SOME of the files needed.  So I just copied from the old folder in the folder "Antivirus" and he hung up the virtual disk of 20 GB file.  So I closed the VI client and checked the vdmk 20 GB folder and back this morning is in the folder with other files.  However, when I try to start the virtual machine, I get the "cannot access a file because it is locked" error message.

  I've done some detective and I noticed that in my second datastore where was the other folder vdmk, the file was now .40kB in size.  Looks like I've lost my other vdmk folder.  What happens here?

  It looks that the virtual machine was still running when you tried to change the name, so the old folder could not be renamed because of the lock. That's why a new folder has been created instead, and why your vm hung on the vmdk file until the lock has been released. Don't know what happened to the 2nd vmdk file, but the file vmware.log in virtual machine directory must have some info as to why does not start the virtual machine. If the 2nd vmdk is gone, this might be a reason.

• No network connection between the virtual machines on different hosts ESXi

  I have several 5.0 ESXi hosts in a cluster managed by vCenter Server 5 and I have network problems:

  1. [Host A] running a virtual machine can ping any other computer virtual running on the [host A] great!
  2. A virtual machine running on host [B] can ping any other virtual machine running on [B] home - very well!
  3. [host A] (from the ESXi console) can ping any virtual machine running on [B] home - even better!
  4. [B] home (from the ESXi console) can ping any virtual machine running [host A] - beautiful set!
  5. A virtual machine running [host A] can not ping any virtual computer running on host [B] and vice versa - bad, very bad!

  So basically the problem is that the virtual machines can communicate on hosts. It is a major problem that I need to fix, for obvious reasons.

  Networking on all hosts is configured exactly the same way: a unique and standard vSwitch with a pair of gigabit network cards grouped, vmkernels configured for the vMotion, NFS and network management and a group of ports configured for the VIRTUAL local area network used by the VMs. (vMotion works fine on hosts, storage vMotion works very well too.) All virtual machines are servers Windows (2003 and 2008).

  Reason #3 and #4 above, my assumption is that #5 must be the result of an ESXi/vCenter configuration issue and not a problem with the switches of material upstream. Is this a reasonable assumption?

  Whatever it is, can anyone offer suggestions on how can I fix? It is quite annoying as I'm pretty sure that these hosts are configured in the same manner as those of our production cluster, which does not at all these problems!

  Thanks in advance for any help you guys can provide.

  To be honest, it looks like a problem with your physical network-

  How is the physical network configured - are NIC connects it to the same physical switches? Are the virtual machines on the same subnet? If this is not the case, they are able to ping the gateway sbnet? Can you piing host IP address from the virtual machines?

  I also moved it to a forum more approiate.

• Get the number of virtual machines per ESX host

  I am able to get the account with the following script command, but what I want to do is to report a 0 if there is no virtual machines on a host.  Currently it just show nothing if there are no VMs.  Any suggestions?

  Get-VMHost | Sort - the name of the property. Select Name, @{N = "VMCount"; E={($_ | Get - VM). County}}

  You can add an IF in the part of the expression.

  Try it like this

  Get-VMHost | Sort-Object Name | Select Name,@{N="VM";E={if(($_ | Get-VM).Count){($_ | Get-VM).Count} else {0}}}

• The list of all virtual machines to a host group in Virtual Machine port group

  Ladies and gentlemen,

  I would like to create a powershell script to list all my virtual machines to a host, but a group of Machine virtual PortGroup... It is possible...? I see only found Internet see the VirtualPortGroup of the host...

  Thanks in advance & looks

  All your VMS have a mapping single portgroup or it not with multiple NICs on different port groups?

  If they are all the same, then the following should work:

  Get-VM | Select Host, Name, @{N="PortGroup";E={$_.NetworkAdapters[0].NetworkName}} | Sort PortGroup, Name, Host

• How one move the templates of virtual machine from one host to another host in the cluster even

  Hello

  Can you get it someone please let me know how to move the templates of virtual machine from one host to another host in the cluster even?

  Thank you

  James

  Welcome to the forums!

  Convert it to a virtual machine (right click on guest and choose the appropriateoption), move it through the migration feature (right-click Guest, and then choose "Migrate") and convert into a model (right click on guest again and choose to convert to a template).

• IO emits virtual machines in a host

  Hi guys

  I have a 2 Server ESXi cluster build 1065491 for a month of monitoring reported some problems with virtual machines - ping has disappeared.

  After that, I found that VMs statement of losers pings were accommodated in the same server ESXi. Today, a problem has been reported with the vCenter apparatus which did not... do more research I found that all of the virtual machines that are hosted in this particular host appeared this message Windows - Linux

  Thanks a lot guys

  Hello

  I do not understand the LSI SAS and mptscsi messages are coming inside the guests who are having a controller LSI. I agree to a point that the vmhba0 of LSI in the server maybe nothing to do with errors inside the guests because you do not have virtual machines in the local data store but CF.

  So, let's take a look at the usual suspects:

  1. as Memmad has pointed out, in the vmkernel journal, we can see if the FC lun is seen no problem and is reported.

  2 the ESX does very slowly during the execution of commands like esxcfg-scsidevs - m or esxcfg-rescan vmhbaX [X your CF Adapter]

  3 - is the lun configured for multi path in the face of questions, CF once again, it can be newspapers vmkernel. ?

  4. I'm sure that the paging file will be generated when the FC lun, but they have a check if the last file to update the directory of the virtual machine swap at the present time. This is to eliminate any delay in the swap file in writing of the customer due to CF issues.

  5. There was questions previous similar to yours as VM lose pings, decline in performance, but they were in iscsi and 4.1 KB here

  It seems that the guests are abandoned or their scsi reset commands that seems to be the issue here.

• Number of virtual machines on a host

  Hello

  I want to count the VM´s on a host and put the value in a variable (number). Then, I want to let the script write the value as follows:

  $numVM = get-VMHost host1. Select @{N = "NumVM"; E={($_ | Get - VM). County}} | ConvertTo

  If ($numVM - gt 0) {Write-Host "host a" $numVM "Virtual Machines"}
  else {Write-Host "the host has no virtual machine"}

  But PowerCLI says:

  Can't compare ' @{NumVM = 3} "'0' because the objects are not the same type or object ' @{NumVM = 3} ' does not implement 'IComparable '.

  So what I have to do now?

  THX

  Chakoe

  Do it like this

  $numVM = (get-VMHost host1 |) Get - VM). County
  If ($numVM - gt 0) {Write-Host "host a" $numVM "Virtual Machines"}
  else {Write-Host "the host has no virtual machine"}

  A select statement creates an object, and not an int

• Deploy multiple virtual machines on several hosts evenly?

  Hello people!

  I wrote a small script to deploy many virtual machines on several hosts at random.

  But I would rather deploy a virtual machine to each host in a table and then start over again until the number of virtual machines to deploy exhausted.  Distribution of the burden of deployment as evenly as possible.

  Anyone have a suggestion?  Example of nested loops?

  

  PowerShell beginner, here.

  Thank you

  romatlo

  One way to do this is with the modulo operator (%), something like this

  $numVMs = 11

  $tgtEsx = get-Cluster "Westcreek | Get-VMHost-name z420 *.

  1.. $numVMs | %{

  [New-VM-name 'Test $($_)' $tgtEsx[$_%$tgtEsx.Count - VMHost]

• How to move virtual machines from one host to another without full VI and vMotion?

  Hello

  could you help me with a question?

  I have two installed hosts with ESXi 3.5 U5, which are connected to the shared iSCSI (Openfiler) - VMs storage are installed on the storage disk. My requirement is to have a cheap solution of DR - in case of failure of a host, I need to move and start VM on the host of work. How to achieve without going through VMware Infrastructure 3.5 and vMotion?

  I found this article:

  http://www.virtualizetips.com/2010/04/how-to-move-a-VM-without-vCenter-or-storage-VMotion/

  but RCLI needs Infrastructure of VMware ESXi does not have default CLI So, how to move VMs between hosts (of course I mean "cold" move) without byuing any additonal VMware SW? It is generally possible in my situation?

  Thank you.

  If the virtual machines are running in shared storage (two guests see the same storage iSCSI or NFS) then it's simple. If a host goes down, then look for the data store on the ESXi host work. Navigate through folders for each virtual machine, right-click on the VMX file and add to the inventory. You will then be able to turn on the virtual machine.

  To move a virtual machine from one host to another, as long as both hosts had the same processors, you can pause the VM on the single host, browse and add the virtual machine to the inventory on the second break host and the United Nations.

  If the virtual machines are on local storage, but the two hosts are connected to the same shared storage, clone virtual machines on a daily basis from local storage to shared storage. Use something like ghettoVCB http://communities.vmware.com/docs/DOC-8760 make the clone. In the case of a server failure, you will be able to browse the data store, add to the inventory on the shared storage and switch the cloned machine.

• Network down frequently on a virtual machine after the upgrade of computers host and vmware to win 10

  Dear all,

  A week ago, I upgraded both my two machines VMWare Win 7 to win 10, as well as the host operating system. also from 7 to 10.

  Now once every 1 or 2 days, one or both the two vmwares aura an esclamation mark on the network status icon in the lower right corner and West no connection.

  The host operating system is NOT having any problems with the network.

  The solution is to disable and reactive the adapter to virtual machines, or repair of running Network Diagnostics where she'll tell me that it s has reinstated the connection to the bridge. But obviously I´d prefer the VM´s to be on the internet 24/7 without my intervention.

  I have another computer on the same router on which I did the same thing, but with this I m not having these problems. A different and not connected equipment via the VPN running on the host OS, which is the case with the machine that s had questions.

  But even once, the host operating system is not having issues, the two VM´s aren´t always the two to have this problem, and this never happened when he was all Win 7.

  I ve disabled some nights windows defender analysis and TCP/IP V6, but neither helped.

  Want to see some of the information from the last network diagnostics / repair or some log file, or you already know what would be the solution to my problem?

  Thanks in advance!

  Best regards

  Well, I thought that a vm was having this problem a lot more often than the other, so I looked for error messages in windows journal, showing that the network problem - have to with DHCP btw - always spent 2 minutes after an event regarding slui.exe, not found on the other machine.

  What I also noticed was that the problematic vm had lost its activation of windows with the upgrade to win 10 (win 10 has limits to how much the same license can be run as virtual machines), is is not the case for the more successful one.

  Then I copied the good machine, which contains the same as the other, changed mac and uuid and now it s showing that enabled, no problem so far.

• Hardware changes reported after moving from the virtual machine to a host of W7 W8 host.

  I tried to move a virtual machine with the guest OS Windows 8 used in the VMware Workstation 9.02

  my HP desktop with Intel core i7-2600 processor, running Windows 7

  to my Toshiba laptop with Intel core i7-4700MQ processor, running the latest version of Windows 8.

  I did something like that all the time with my old laptop with i7-2630QM running Windows 7.

  It turns out that something changes significantly when the host of the laptop operating system passes W7 to W8.

  After starting the virtual machine on my laptop W8, I clearly stated it had been MOVED and NOT copied.

  Unfortunately when I try to use one of the Office 2010 applications, I get a message that the change of
  HW has been detected, and that I must again request (purchase new license I guess).

  Can someone help me solve this problem. For me the time is important.

  I'm leaving for a business trip to 3 weeks and the old laptop is no longer appropriate.

  Andrew J

  Hello

  It seems to be normal, because the changes to the hardware (RAM, CPU,...)

  may be a reason for reactivation of Microsoft Windows or Microsoft Office.

  I had such a situation, the upgrade of RAM.

  So if you have the license, activate it again.

  Hope has helped you.

• What is the best way to restore virtual machines after a refresh of the server

  Hi all

  First time poster here. A group of people at my work have their own VMWare environment which they install later. It has 3 virtual machines running on it, and they want to set up a fourth. Unfortunately the new machine, they want to put in place is going to be almost 1 TB in size, and they initially setup the VMFS datastore to 1 MB, which means that a machine can be as large as 256GB.

  Research, it seems that there is absolutely no way to work around this problem, except to redo the data store. Is this correct? If this is the case, I was looking at a way to save the three current machines and to reload them after it is updated. A way that I thought was to go browse the data store and copy all the files on my local machine to the virtual machine (.nvram, hard, .vmx etx... all the files), wipeout and redo the ESXi host with the correct setting of data store, build the machines VMS in vSphere, and then replace the files with those copied. This works perfectly? I don't see a lot of information out there about it and I want to make sure that I have not to spoil the VMs. This environment consists of 1 ESXi host with all the local storage (2 TB).

  Also, if anyone knows a better way to do this, please feel free to give your comments. I would really appreciate it.

  Thank you

  Yes, unfortunately there no way to change the block size of the datastore to vmfs without reformatting.

  Yes, it will work. You have just to copy all files in this VMFS datastore to a place safe and download once the block size has increased. Once the download is complete, navigate to the virtual machine, the virtual machine folder right click and save the VMX.

• Unable to start the virtual machine after restoration

  Guests including Test host: ESXi 5.1.0.1065491

  Vm problem: 32-bit, Server 2003

  I use Veeam Backup & Restore 6.5 to back up my vm.  I always do a test restore to ensure that my backups are good.  I'm having a problem with a restore.  The 32-bit Server 2003 vm starts just fine on the main host it runs on.  All the vm are 64-bit except for one who is a 32-bit Server 2003 vm.  Restoring the machine virtual and implemented on a host except the 32-Bit vm Server 2003 test.  After restoration and trying power to the top, I get the following error:

  Unable to start the virtual machine.

  Turn on VPCM module has failed.

  Viewed performance counters require version 3 or greater of architectural performance monitoring.

  Anyone know if there is a fix for this problem?

  TIA,

  Mux

  I assume you are using different hardware (CPUs, the BIOS settings) for VMS restored!

  The virtual machine has VPCM enabled, which causes the problem. You can either disable it in vSphere Web Client (you can do this in the vSphere Client Windows), or directly modify the .vmx VM by setting vpmc.enable to "FALSE".

  For how toggle this setting in the Web Client see allow virtual in the Web Client vSphere CPU Performance counters. If you want to edit the .vmx file manually, you need to delete/re-add the VM from the inventory or recharge (see http://kb.vmware.com/kb/1026043)
