PowerCLI Script to migrate virtual machines with the same network Source for the new vCenter Server.

• PowerCLI script to migrate virtual machines to the new vCenter environment

  Hello world

  in the next few weeks, we need about migrate 700 VMs (Windows/Linux) server to a new environment (new vCenter, new hosts, but VMs will remain on same data warehouses). VMs will be migrated not in one batch, but rather from time to time (which, however, can understand the need to migrate some 10s of virtual machines at the same time).

  Cluster names and folder structure will be identical to the old and the new vCenters. As host in the new vCenter names differ from those in the old vCenter, thought to provide a table of 'translation', which tells the script to save a given VM on host B (new vCenter) when having been registered in order to host a (old vCenter) and so on.

  I thought writing a PowerCLI script which, broadly speaking, can accomplish the following steps:

  • Connect to vCenterOld and vCenterNew
  • Correspondence table of host to read from a file (see step "register VM vCenterNew below)

  Then, in a loop:

  • Ask VM name
  • Get the settings of the virtual machine: Datastore/path, network/Portgroup, HA restart priority, host, folder, note
  • View the parameters and the VM name and request confirmation migrate the virtual machine
  • Turn off VM (closed OS gracefully, but force power off if power status is still not equal 'off' after a time given)
  • To unsubscribe from VM vCenterOld (removal of inventory)
  • Registry of the VM to the data store vCenterNew (assumptions: same folder as vCenterOld, host names are different, but for each source in vCenterOld host a host of destination in vCenterNew for you join the virtual machine to can be provided, that is, CSV)
  • The value of VM portgroup (same name as in vCenterOld)
  • Set VM HA restart priority
  • PowerON VM
  • Wait / check the VM (for example, ping) connectivity / continue immediately if the virtual machine is accessible or after a certain time if the virtual machine is still inaccessible
  • Confirm that the virtual machine has been migrated successfully, OR ask the user to check the connectivity of the virtual machine

  Now to my questions:

  • Is anyone know about an existing script that does something similar or contains parts that can be useful to compile a script like this?
  • How can vCenter two connections at the same time been managed within a PowerCLI script - or doesn't work at all and a connect/disconnect to/from the two vCenters must be completed for each virtual computer?

  Many thanks for any help.

  The following seems to work for me

  $vm = Get-VM -Name MyVM$nic = Get-NetworkAdapter -VM $vm $vdPG = $nic | select -ExpandProperty NetworkName
  
  Get-VDPortgroup -Name $vdPG
  

• Create the virtual machine with the type of controller SCSI LSI logic SAS with PowerCLi

  Hey guys,.

  IM the difficulty to create a virtual machine with the type of controller SCSI to "LSI Logic SAS". The cmdlet New - VM im struggling to find where to create the type of controller?

  If you create a virtual machine without specifying a disk it will create a 4 GB SCSI type thick (0:0) hard drive 1 with 0 Parrall default BusLogic SCSI controller.

  What im wanting to do is to create a disk hard which is thin Prov. and create SCSI LSI logic SAS controller is set to.

  New-VM -name VMSTORE23 -$vmhost $esxhost MemoryMB- 4096 NumCpu- 2 -NetworkName "Vlan 6 Machine Virtual Network" | Get-NetworkAdapter | Set-NetworkAdapter -Type Vmxnet3 -MacAddress '00:50:56:00:00:21' -confirm:$false

  I have recived of aid by some LucD who helped direct the value of the network card in the New - VM cmdlet as follows. But I'm not able to add a hose for hard disk also like:

  | Get-hard drive | Together-hard drive - Datastore $datastore - slim StorageFormat

  And I have no idea how change the type of SCSI conroller or create it with the correct configuration?

  Any help would be great,

  Thanks in advance

  Eddie

  Greetings, steddyeddie-

  You should be able to use Set - hard drive and SCSI controller Set cmdlets to set the storage format of your hard drive and the SCSI controller type, respectively.  You were close to on the part of game - hard drive .  Try something like:

  ## get the VM object $vmVMSTORE23 = Get-VM VMSTORE23 ## set the harddisk storageformat to thin$vmVMSTORE23 | Get-HardDisk | Set-HardDisk -StorageFormat Thin ## set the SCSI controller type$vmVMSTORE23 | Get-ScsiController | Set-ScsiController -Type VirtualLsiLogicSAS
  

  It could pack in to your existing order to keep it as a good word, but for readability.

• create a new virtual machine with the default settings?

  I was wondering if there was a way to create a new virtual machine with the default settings.

  For example, let's say I want all new Lion VM to have 2 CPU cores. Is there a way to set this automatically? There are other parameters I want a new machine to inherit automatically, I was wondering if there is an automatic way to do this, or is it a feature request...

  Thanks in advance

  Just for my clarification, when you say a vm model, basically I would execute a finder copy then drag back to the VM library, right?

  Yes.

  On the orders of spcirpting, it would be unix commands or are there specific vmware controls that make your job easier (in Applications/VMware\ Fusion/content or elsewhere)...

  IIRC, VMware Fusion 3 and later versions has an AppleScript dictionary, but it is not yet officially supported and may not be able to do what you want so, basically, only Unix Shell scripts, that's what I was referring to.  For an example, see my script attached to the following response: Re: vmware - script of the creation of the vm and the operating system installation process

• Let me know scenarios when different virtual machines with the same UUID are created in VMware Hypervisors?

  Let me know scenarios when different virtual machines with the same UUID created in VMware Hypervisors, aside from editing the .vmx file?

  The only other way I've seen is when you manually copy the virtual machine to another location on the data store (or another data store) and then when turn on/off the virtual machine, select I moved, rather that I copied it (the default option).  This will keep the same UUID.

• Start and stop Virtual Machines with the system

  Hello

  In a server cluster @vcenter HA/DRS 5.1, I enabled start and stop virtual machines with the system option but after I checked two days later, he is off again somehow. What makes this option off? I had a power failure in the datacenter. vCenter server has not been upward. I started all of the ESXi servers manually then went all VMs account is declining. I want that they start automatically when server ESXi upward.

  Thanks in advance,

  Thank you. This option is more valid than if the hosts are part of an HA Cluster license. I suspect that you configured through the traditional vSphere Client and that it is a bug with this client. If you try with the new vSphere Web Client, you will find a notice that it is disabled and there is no button "Edit".

• Impossible to turn on the virtual machine with the following error: could not open the disk ' / path/to/vmdk-0001.vmdk ' or one of the Flash disk it depends on. Reason: Broken pipe.

  After the movement of virtual machines in VmWare Server 2 for ESX 4i, I get this error when you try to start the virtual machine:

  Impossible to turn on the virtual machine with the following error: could not open the disc

  "/ path/to/vmdk-0001.vmdk" or one of the Flash disk it depends on.

  How did you move virtual machines?

  Did you use the converter (https://www.vmware.com/tryvmware/?p=converter)

  Otherwise try converter

• Migrate virtual machines from HP G7(single host) for HP G8 (Cluster) without shared storage

  Hello

  I have 2 esxi host (hp dl 380 G8) and put them in a cluster and other host esxi (dl 380 g7) and I have no shared storage and use local disks just now I must spend my VM G7 server a cluster of the G8 but I want to know I can join my cluster g8 g7 and migrate web vmware machines without any downtime?

  I want to know can migrate without downtime with localdisk? I have no shared storage

  Best regards

  BAbak

  can I join g7 to my cluster of the g8

  You can mix into clusters hosts all desired, even Intel and AMD at least that you enable EVC on the cluster (of course, HA or DRS require shared storage compatible/CPU). However, you need not to have even just cluster hosts to migrate virtual machines through vMotion between them.

  migrate web vmware machines without any downtime?

  Don't know what this "web vmware' but yes, because ESXi 5.1, you can use"enhanced vMotion"to live migrate virtual machines without service interruption from one host to another, even without shared storage:

  Migration with vMotion in environments without shared storage

  The usual vMotion requirements apply. Also you can only live migrate virtual machines from the old host to the new hosts because of different generations of CPU (and back as long as you don't have bike powered virtual machines on new hosts).

• How can I move virtual machines from a local data store for a new iSCSI SAN?

  Hello guys,.

  Now that we have a new iSCSI SAN market how can I tranfer all the virtual machine to a local data store for a new SAN? Can I stop the VM in the host, and then copy the DataStore files with all the info on the new volume?

  Thank you

  Pesinet

  Alternatively, you can use VMware converter or cold Migration / Storage VMotion if you have the appropriate licenses.

• Create the virtual machine with the ISO mounted CDROM

  Community of hell!

  Working on the vmcreate.pl script to add the creation of CD-ROM with iso data store, I got stuck on the error

  ' Invalid device configuration: ' VirtualSCSIControllerOption.numSCSICdroms '.

  I'm sure I'm missing something obvious, or this option but may not understand how to deliver this.

  I created a cdrom as follows (below test I create any CDROM, no iso file to reduce the number of layers):

  my $ BPPRR m_backing_info = VirtualCdromRemotePassthroughBackingInfo->new)

  deviceName = > ' '.

  exclusive = > 0,

  );

  my $description = description->new(label = > 'CDROM', summary = > 'cdddrom');

  my $connectable = VirtualDeviceConnectInfo->new(allowGuestControl = > 1,)

  connected = > 0,

  startConnected = > 1,

  ( State = > inmates ' / ' );

  my $ BPPRR m = VirtualCdrom->new(backup = > $BPPRRm_backing_info,

  connectable = > $connectable,

  controllerKey = > 0,

  deviceInfo = > $description,

  key => 1,

  ( unitNumber = > 1 );

  VirtualDeviceConfigSpec->new(device = > $BPPRRm,

  operation = > VirtualDeviceConfigSpecOperation->new()'add'));

  Did anyone have working example to create the virtual machine with CDRom?

  Andrey

  If someone will find this useful I followed this route Re: vmreconfig.pl add the device CD/DVD fails if the virtual machine created with vmcreate.pl

  and also I found good examples of what I need to in VMUtil.pm in cmd vmsphere libraries.

• How to clone a virtual machine with the drive?

  Hello

  Previously, I used VMware Workstation and has a mastery of "clone". Now I use the reader and I would like to clone my current VM and there is no special orders. Simply copy the directory would probably not there a lot of information such as DNS name, etc. that are likely to be changed. Is it possible to clone a virtual machine with player or do I Workstation?

  Many thanks in advance,

  Nicolas

  In my computer a full clone is nothing more then is not a copy that was made unique in the process and the players of VMware capacity but there is nothing stopping you from manually making a copy and then manually by making the changes to make it unique.

  Host-Only is VMnet1, you used only NAT. static use of intellectual property and switch to DHCP for now. Make sure that the VMWare DHCP Server service is running. Put network cards in comments to "host-only '.

  Post your host ' ipconfig/all'.

• Create a virtual machine with the physical RAM total?

  I want to virtualize ESXi 4 on my MacBook Pro. However, I have 2 GB of RAM and ESXi 4 requires a minimum of 2 GB.

  I posted in the community of ESXi (is it possible to virtualize ESXi 4 with less than 2 GB of RAM?) and there is a solution for using ESXi with less RAM, but the problem is that I first need to run the installation with 2 GB.

  Basically, I tried to create a virtual machine with 2 GB, but the maximum I can use is 1840MB. Is it something that I do with Fusion to increase this limit? I understand that I am under a host operating system and requiring too little RAM, but just to get through the ESXi installation isn't it possible to push the VM of RAM to 2 GB and the host what OS increase the pagefile to deal with the lack of RAM?

  Any help would be appreciated!

  Thank you

  You may be able to edit the .vmx file and change the memsize option either 2048 or more. The merger is able to start a virtual machine with more memory that the host, just UI prevents common users to exceed the limits of security in general.

  I'm not quite sure what would happen if the VM actually tries to use all of the memory. If all goes well, it will be just talk and run slowly. Of course, the worst case are that it crashes.

• Limit a group only port to be added to virtual machines with the role

  Hello!

  We have two 5.1 (soon to 5.5) Vmware ESXi clusters to total 10 hosts. We are setting up the new virtual machines for the Department of finance where they want to ensure that a level 1 technical support cannot access. On the side of the virtual machine, it's easy enough - but we want to make them a regular technician can also put a virtual machine on the portgroup (and VLAN) that these machines will be also on.

  Is there a way to limit a single portgroup to be assigned to any virtual computer through roles?

  Thanks in advance!

  His quiet easily. Go to vCenter.--> Home---> Networking.

  Select the Portgroup where you want to restrict users. Go to tab permissions, do a right click and add permissions.

  Add all users and groups that should not have access to this and give as no access. They would never know that there
