• 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.

• How to reinstall the OS on a virtual machine in the virtual machine Linux drive?

  Hello

  I have problems reinstall OS in a VM Linux (on the Linux host).  I change the CD/DVD (IDE) to connect to an ISO file, save and then play the virtual machine.  I tired send "Ctrl + Alt + Delete", running after stopping, etc., but it will not re - install the new ISO standard (each time it's booting of the operating system already installed).  How can I force the VM to re - install a new ISO standard?

  Thank you.

  Hello

  You can delay the start of the machine, press ESC at startup and choose to boot from the CD to the virtual machine. You can also change the boot order in the Bios to automatically boot from the CD first.

  Take a look at the following kb for details on how to change the way the virtual machine starts.

  Good luck!

• Migrate the virtual machine for Exchange 2010 from one host to another

  Dear members,

  Please let know us if the migration of a virtual machine for Exchange 2010 is supported to an Esxi host to another, the Esxi version is 5.0.

  There are unique Exchange environment with the role of hub, CAS and mailbox on the same virtual server. We have a maintenance window and we think moving exchange virtual machine from one host to another, but before that I need to be sure if it's supported my MS and do not want to have problems after, because I have also gotten to know here in the forums this snapshot for Exchange 2010 is not supported by Ms.

  Please notify.

  Kind regards

  I'm not aware of any limitations with VMS Exchange migration. Anyway, you can consider running the migration during the low workload.

• Move the virtual machine Linux from AMD to Intel

  Hi, I'm running several CentOS 5.4 and 5.5 virtual machines on an AMD64 based host ESXi 4. I need to replace the AMD ESXi 5 host and move the VM to host Intel based host with an Intel-based.
  
  I did it with a VM test (cold migration), and it seems boot, but I read that I might need to change the kernel for Intel.  Is this necessary?  If so, can someone point me in the right direction on how to do it?  Thank you!

  If the test computer worked then no there is no need to replace the core.

• Migrate the virtual machine fails - "a general system error occurred.

  I have a host in my cluster which I am unable to migrate all the machines. Migration always fails at 13% with the error "a general error has occurred: There is no message after the colon. In tasks and events, I see the following under events:

  • "Migration error" warning: a SNMP trap was sent
  • Alarm "migration error" [name of the VM] action
  • Alarm "migration failure" changed from gray to gray
  • Cannot migrate to [NEW HOST], [STORAGE]

  The substantive test on the list is the first.

  VCenter is version 5.5 and ESXi is 5.1 on the source host and destination.

  The lack of information in the error message let me very well what to do next. It is a cluster of production so I'd like some suggestions that don't involve slaughter the hosted VMs. thanks in advance for your help.

  Take a look at this KB: KB VMware: VMware ESXi 5.x host stops responding when you try a vMotion migration or a configuration change

• Best way to migrate virtual machines to new ESXi hosts with a different configuration of networking.

  We currently have a cluster of 6 Dell machines that move VM 120 or so on ESXi 5.5. Networking consists of a dVswitch with 6 uplinks that map to 6 x 1gig physical NETWORK adapters on each host ESXi... These are grouped into 3 trunks / gal, so we have 2 GB by SHIFTING of the bandwidth and failover. The LAGS are configured as follows:

  LAG1

  Traffic to our (NFS) shared data store and management of ESXi. (vmk0)

  LAG2

  Access to the network of the VM - groups of different ports on different VLANS

  LAG3

  vMotion (vmk1)

  We just bought 6 new Dell machines that have connections fiber 2 x 10gig each. The idea is to bring together in a 20Ggig LAG by machine that will handle all of the traffic, so traffic NFS data store, network traffic from the VM, vMotion and traffic management ESXi.

  
  

  What is the best way to migrate the virtual machine in the cluster existing to the new machines? Many of the virtual machine are essential, so we cannot stop time.

  
  

  Can I create the new DELAY on existing dVswitch and put it as an auxiliary card? I'll be able to do it for all 3 of the above both above LAGS?

  
  

  Thanks for the info Alistar, it's almost here. The bit that was me stumping was that after establishing a new dVswitch I received messages that the new dvSwitch was not reachable on the old host, when I tried to migrate the virtual computer.

  The solution (with the permission of VMware Support) was that I need to add the two dVswitches to one of the old hosts, then assign a physical alternative on this host uplink to a temporary 3 uplink on the new dVswitch. I then tag all the relevant VLAN that uplink.

  This way I can first migrate the virtual machine to the new dVswitch networking so I can move the computer to the new cluster.

  Obviously I can only migrate from old to new cluster with a single host. each virtual machine must be a double for the host with 2 switches, and then to the new cluster. I also had to have the two dVswitches to the same version.

  Fortunately, I had a physical rising spare on the hosts of the old, otherwise I would have had to break one of the trunks and re-use of one of these uplinks.

  Oh and be aware, impossible to use the same names for groups of ports 2 DV switches, they must be unique!

• cannot not power off the virtual machine, but don't think the host it is running!

  I have two clusters VI3. An older cluster to 3.02 hosts and a new cluster with ESXi hosts. Level of current patch on ESXi hosts. New guests and old presenters sees the same storage, but I have additional storage which can see only the new virtual machine.

  Most of the migration to the new cluster went very well. A few questions. But a VM just GIVES me fits.

  After the failure of attempts to migrate the virtual machine to the new storage, I thought I just migrate the virtual machine to the new host and leave it on the old storage, for now, until we could find something later. VCenter events logs show that the migration has expired. However, the virtual machine appears in the new cluster and is no longer in the old cluster. Also, he turned on itself for some reason any. Turn off in Vcenter gives the error "the operation failed because another task is underway." Having the VM that I could put it off in before Vcenter, and no no unsure of how to use the RCLI for this, I have connected to the host directly mode "not supported" and has run vm-support - x to get the list of running virtual machines and their ID's so that I could kill him. However, the host does not include this virtual machine in the list of virtual machines. So I think a virtual computer that runs Virtual Center, but he thinks the host it runs on is unclear if I can't kill the process.

  Help?

  Have you tried to restart ESXi management officers, as well as the vc service is restarted?

• 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.

• Migration of virtual machines in ESXi 4.1 to 5.5 to new hardware

  I'm new to VMware and our company bought 4 new servers and a SAN to replace our old VSphere 4.1 installation of 12 year.  The old configuration consisting of a server VCenter 4.1 physics 2003, 2 Dell 2900 ESXi hosts and 1 MD300i SAN.  Gen9 again the Installer 4 HP DL360 (3 host 1 VCenterServer) and MSA 2040.  Can someone please explain to me what would be the best way to go about moving more of our VM current for the new hardware? I found this from a previous post here, but it does not move the virtual machine to a SAN to another.

  Migration of the VMs of ESXi 4.x to 5.5

  "If I understand your question, continue to build the new environment of 5.5 with your 3 hosts from scratch 'ignoring' your old hosts. Once your new environment up & running, connect 4.1 guests to your new server vCenter Server and vMotion to move virtual machines while they run to the new cluster (live migration without interruption).

  VMTools upgrades do not have place automatically during migration.

  Once your virtual machines on new hosts, update tools as usual and you can then also upgrade virtual hardware of your virtual machines.

  Virtual HW update is optional, though; If you do not have the VMs that need the new features you can skip this last step and keep them as they are. »

  TYIA.

  The previous answer is pretty good, but I would like to add a few elements.

  You can 'disconnect' your 4.1 hosts of your old vcenter with running virtual machines, and then when you connect the hosts in your environment of 5.5 it will import your VM running as well.  As long as you have properly configured virtual networks you can live migrate vmfs old host and the old store of data simultaneously via the web client as long as your esx license allows it.  Otherwise close your virtual machines down to 1 at a time to migrate them above.

  Alternatively, you can consider running your vcenter as a virtual machine within the cluster it manages.  This gives you some DRS and HA for vcenter, plus a 4th host for virtual machines.

  If you don't have additional license you can also install your new hosts of 5.5 and run for 60 days before that you upgrade your 4.1 licenses to apply to your new host.

• Migration of virtual machines to vCD and again in a standard ESXi cluster itself?

  We currently have a relatively small cluster of ESXi (5.0.0 1489271) which uses a dedicated installation vCenter (5.0.0 1300600) and an instance of vCD (vCD 5.1.2.1068441).  Our goal is to move the virtual machines running in this configuration to our standard ESXi clusters (5.5.0 1892794) supported by installation of different vCenter (5.5.0 1891313).

  The instance of vCD seems to add additional parameters to the level of the virtual machine that prevents the VM of to be easily transferred out of the instance of vCD.  What we are looking for is a way to easily migrate these servers on and completely remove the vCD of the equation.  The only details around that we found cause downtime for exports out of vCD can be extended to reason the total amount of drive to the VM and VM level, which we really do not think it is an option to open a window of time to stop long enough to work through this process.

  Did someone went down this road before?  We have approximately 120 virtual machines in the cluster vCD using about 52 TB of disk.

  Maybe we're wrong understand something fundamental about the nature of migration of VMs on the vCD instance, but we have not been able to find many details on what options exist to make this move.  We have spoken several times with VMware support in this regard.  They mentioned a potential tool in the work within engineering migrate vCD to vCAC (which isn't really fall under our goal unless vCAC would then provide a clear path to return the virtual machines to a standard ESXi cluster).

  Any suggestions or ideas are appreciated.

  I am a colleague of GTC and wanted to just sent to our discussion of this topic with the help of VMware.  Basically, we should be able to Setup VMs in vCenter, outside of vCloud Director, pointing them to the same files VMDK and MAC then power off VM vCD and power on VM vCenter.

  : The NASA-EAST region

  Moment of validation: 2014-09-05 11:32 EDT

  Severity of the request for assistance: 4 - low

  Description of the request for assistance: we are looking for ways simple and less disruptive migrate VMS off vCloud Director and vCenter management.

  We have the advantage of a single principle in vCloud, managed by a vCenter and the network configuration is simple with no VXLAN.

  What are the problems with the realization of the following?

  vCD 5.1 is managed by vCenter 5.0, the final result will move VMs in vCenter even

  -Create a new virtual machine in vCenter that points to the same vmdk files as virtual machine in vCD you want to migrate, allocate same configurations of processor, memory, and network (we do not use the vCD with advanced networking)

  -Turning off the virtual computer in vCD

  -Once the vCD WHAT VM is off, power on VM in vCenter

  We must ensure that the VM vCD never gets turned on again and then when we are completely finished with all migrations of VMS in vCenter we abandon vCD.

  Of course there are details to help users migrate to how they use the vCD to vSphere vCenter client web interface or web interface.

  Entry date: 04/09/2014

  Since the opening of the case, I had interviews with several members of VMware support staff and these additional points were added.

  -Configure vCenter VM with the same vNIC driver MAC and like vCD VM vNIC

  -Rename VMDK files to make for easier management, or if not renamed then detach from the propelled out of vCD VM

• Can I register the Virtual Machine of VMware player esxi 4 4.1?

  Hi all

  There are a few virtual machines running in VMware player version 4, now I need to migrate on ESXi 4.1...

  It's Possible he just copy and past the files of virtual machines running in vmware player in the data store then register the same in the esxi server and power on... This will not work?

  because I do not V2V method...

  With respect,

  Pascale Vimal

  You run the virtual machine on HW 8, that you will not be able to simply move the ESXi machine.

  The only supported option is to do a conversion on reviews of downgrade the material relating to immigration to vSphere

• Help the migration of virtual machines

  My company is changing the data center in a co-location facility.  How the migration is performed, there are ESXi hosts and storage shared at Camp already.  Data warehouses are replicated to the storage to the camp of data stores with the same name.  The plan was to stop the virtual machines in the data center, removal of the inventory, browse the data store of one of the colo ESXi servers and add the virtual machine to inventory... Rinse and repeat.

  The problem we encountered had to do with the fact that each virtual machine has VMDK on several data stores.  This process only acknowledged the change of the primary VMDK, VMX file was always looking for 2 other volumes on the old warehouses of data, which could not be accessed camp.

  I have to think that there is a way to generate scripts to avoid this problem to occur.  If we know the identifier for the new storage volume, we should be able to generate scripts, Yes?

  I would like the script to read the VM names from a txt file, remove the virtual machine from the inventory on host1, browse the host2 data store (which is at Camp) and add the machine virtual inventory and then remove and re-add the other volumes, based on the name of the data store (if hard disk 2 is on datastore2 then use 9d0fac87...)

  Any help would be grately appreciated!

  Thanks in advance!

  Hello, BenLiebowitz-

  I looked through your script.  You were just on a good amount of it.  There are a couple of things to tweak and a number of things to correct.  Here is the script of update from what I've seen would / should change (and here is the explanation of the things that I've changed the code).

  # export list of Staging VMsGet-Folder -Name "Staging" | Get-VM | select Name | Sort Name | Export-CSV "c:\staging.csv" -NoTypeInformation
  
  # Get Staging VMs$stg = Get-Folder -Name "Staging"
  
   # Shutdown VMs (cleanly)$stg | Get-VM | Shutdown-VMGuest -Confirm:$false
  
  # Remove Hard Disk 2 and 3$stg = $null$stg = Get-Folder -Name "Staging"    ## getting Staging folder again$hdName2 = "Hard disk 2"$hdName3 = "Hard disk 3"$stg | Get-VM | Get-HardDisk -Name $hdName2,$hdName3 | Remove-HardDisk -Confirm:$false
  
  # Remove VMs from InventoryGet-Folder -Name "Staging" | Get-Inventory | Remove-Inventory -Confirm:$false
  
  ## then, disconnect from the vCenter to which you were connected
  
  ## then, when connected to the vCenter server in the co-location facility:# Add VMs to Inventory$esxhost = "prpp6-vmwhst23.i3global.net"$datastore1 = "someDatastoreName" ## need to set this value!
  
  ## and, add hard disks back to VMsforeach ($row in (Import-Csv c:\staging.csv)) {    $vmName = $row.Name    $vmxfile = "[$datastore1] $vmName/$vmName.vmx"    $vmNewVM = New-VM -VMFilePath $vmxfile -VMhost $esxhost
  
      # Add hard Disks 2 and 3    New-HardDisk -VM $vmNewVM -DiskPath "[transient_deviceid] $vm/$vm.vmdk"    New-HardDisk -VM $vmNewVM -DiskPath "[data_deviceid] $vm/$vm.vmdk"} ## end foreach
  

  Comments about what I've updated / changed:

  • To stop the virtual machines, you should be able to all channel the results of Get - VM directly to Shutdown-VMGuest (I rewrote which)
  • to remove the hard drive, 2 and 3, you can use the cmdlet Remove-hard drive and do it in the pipeline (I rewrote which)
    • the ' $vm = Get - VM $stg | Get-show"line in the foreach loop was going to be problematic, as you had: '$vm' contains managed objects views for all the virtual machines in the folder of staging, not only of the virtual machine currently being acted on this iteration, so things have been broken
  • the remove inventory line, you might want to add "-confirm: $false", as the default behavior may be at the request of confirmation
  • the "$esxhost = prpp6 - vmwhst23.i3global .net' line needed quotes the host name
  • you do not use the $fields variable anywhere, which can be removed
  • I've renamed the variable '$add' to '$row' for a little more clarity
  • in the part that adds the virtual machines to the inventory in the co - lo vCenter:
    • the part that tries to set the value of "$vm" is not quite right; I've updated that (and changed the name of the variable "$vmName" for clarity)
    • you did not initialize the variable "$datastore1" - you must set a value for it (and how you use it assumes that all of the virtual machines in the co - lo facility are on the same data store - is this the case?)
    • you need square brackets around the name of store data and quotes around the value for $vmxfile
    • for the call of New - VM, you might consider providing a folder with - location (if you want the VMs newly saved to a particular folder)
    • for calls of New-hard drive, you need quotes around the value - DiskPath

  I would give that a shot with just a single machine and see how things are going.  Let us know the result.

• Moving the virtual machine containing vCenter to another host ESXI

  I am currently learning/building my first setup of virtualization. I made the mistake of letting the size of the block of the data warehouses to 1 MB. Now, I need to rebuild one of my stores of data.

  I could use vcenter for all my other VMS out migrate to another server esxi. I do not know how to move the VM vCenter, because he must be stopped to be moved, but I need to use the tool of migration/converter to move, which seems quite accessible from within the virtual machine.

  Any ideas?

  Stop vcenter Server and unregister (remove the inventory) of the inventory of the ESXi host. Then use example of Veeam FastSCP to copy some files/folder of the virtual machine to the other hosts data store and register the virtual machine to the inventory of the ESXi host by right-clicking the file vmx (add to the inventory). Make sure that there are no snapshots on the server vCenter Server!
