• 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

  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]

  }

• deploy multiple virtual machines using vmdk and SID file

  Hello

  Need to know if I am correct or miss me something... I deploy many virtual machines using method.

  1. remove the vmdk files a XP.

  2. create new folders and copy the vmdk into this folder.

  3. create virtual machines using existing vmdk files.

  4 rename the computer and join it to the domain.

  My question is, my VMDK files are an existing xp VM (no longer exist), what is the status of the deployed virtual machines? they still have the same SID or it is changed? I managed to join to the domain, but do not want surprises in the future.

  Note:

  I had another option, could have all these automated with new SID using PowerCLi, unfortunately, osCustomization has default, I can't event run the get-OsCustomization command, it keeps failing.

  Thank you.

  Yes, Windows writes the SID on disk (virtual disk for virtual machines) or physical disk for physical machines.  The guest operating system has no idea on the vmx file.

• Deploy multiple virtual machines from one model to the help of customization of the OS and a text file for hostname and IP

  Hi all

  Not sure if this has already been answered, I did a search on the forums, but couldn't find an answer to what I'm looking for.

  I want to fully automate the deployment of multiple VMs of a model using a customization file, but also to retrieve the host names and IP addresses from a text file / spreadsheet.

  for example:

  I need to deploy a test environment of 30 virtual machines using the template file and customizing TestVM. I have a spreadsheet with the VM host names and IP addresses. The process now is to manually enter the host name and IP when the customization file invites to do while deploying them in each virtual machine. The customization file takes care of the rest (license key, admin password, add to the domain etc.) can I automate entry of the name of host and IP addresses in reading from a text file?

  Thanks in advance!

• Mount a file ISO in multiple virtual machines simultaneously.

  Hello

  I found I can mount the same ISO file to virtual CD 8 VM simultaneously, but failed with the ninth VM. Is there a limitation on this subject?

  Thank you.

  The ISO is mounted in a virtual machine running on an ESX ESXi host, a file lock is held on the ISO file. Each host for the file connection consumes a lock. There is a maximum of eight locks possible for a file residing on a VMFS 3 datastore. This limits the amount of hosts of virtual computers that can access a disk for a cluster of eight ESX/ESXi hosts. This restriction applies to the files of virtual disk (VMDK), ISO CD/DVD images, floppy disks or any other file.

• Starting from multiple virtual machines simultaneously

  I've slowly been deployment of thin clients in my desktop using PCOIP and view 4.5.  Lately, I've noticed that when enough people begin their computer at the same time the connection to the server view will not respond until the first on that some computers are up and running.  Is there a setting somewhere, using the VSphere, which dictates the number of virtual machines or may start at the same time?

• from multiple virtual machines simultaneously

  How can I put the start-vm cmdlet to enable me to launch 40 VMS with different names at the same time.

  I tried to do it this way

  I connect on the vcenter server and these VMs are spreadout between 6 different hosts in a cluster

  Start-VM - vm (vm-get-name sales *, salesams *, salessvr *, devsvrs *)

  What would be the best way to approach this task? any help is appreciated!

  Hello, Sith-

  Yes, it works like:

  Start-VM -VM (Get-VM -Name sales*, salesams*, salessvr*, devsvrs*) -RunAsync
  

  Otherwise, you could get the VMs and then redirect it to Start-VM with the same net result:

  Get-VM -Name sales*, salesams*, salessvr*, devsvrs* | Start-VM -RunAsync

• Controlling multiple virtual machines on multiple hosts?

  Hello

  My apologies for what will clearly be a newbish question because I just started using PowerCLI yesterday. I have 6 servers hosts with 10 virtual machines on each and every VM with a snapshot.

  I created a script for

  (1) connect to Host #1

  (2) to reset all 10 VMS to the snapshot (a)

  (3) power on all virtual machines (simultaneously)

  (4) connect to the host #2... Rinse and repeat at host #6.

  It takes a little more than 5 minutes. I'm sure that this process will speed up if I find the answers below:

  Two questions:

  There's a way to connect to all servers at the same time, so can I have step #3 works on all servers host 6.

  -Is it possible to have the step #2 run simultaneously on each host to save on time?

  Thank you very much!

  With the Connect-VIServer cmdlet, you can connect to several servers in vSphere.

  Only condition is that you can use the same credentials, or this UNIQUE authentication is implemented.

  When you switch to view "multiple" with the Set-PowerCLIConfiguration cmdlet, you can run cmdlets against all those servers at the same time.

  You can now do a 'Get - VM"which will return all the virtual machines on all connected servers vSphere.

• Is it Possible to access only bypassed FC HBA to multiple virtual machines

  Hello

  I have a FC HBA on my 5.5 ESX. Server. It does not support the function of SR - IOV. Is it possible to access this FC HBA across multiple virtual machines?

  If possible, please provide as follows to go further.

  Kind regards

  Aashish

  It is not possible. The basic material underlying PCI specification does not have a single shared between several independent operating systems PCI device.

  SR - IOV solves by creating the virtual function peripheral PCI, but as you mentioned, that he can't stand not and first of all, ESXi supports that SR - IOV for Ethernet network devices and not for native FC HBA (excluded FCoE) functions.

• GUI: how to run the same command on multiple virtual machines at the same time?

• Help for a demo: create multiple virtual machines

  Hello

  I am a beginner in vCO, I completed the installation and configuration with success and I started to create workflows, but I guess that I need help with an example that I started yesterday:

  I am creating several virtual machines at the same time, I mean all the user have to do is say how VMs, he wants to be created and the workflow must do the rest, but I don't know what is the best way to do so, in the present workflow in the library , find us only 'create simple VM' so I added a few scriptable tasks to this workflow, but still can't do what I want.

  Any solution plese? or a few best practices to perform this type of workflow? Maybe I missed a workflow can create multiple virtual machines with different names but the same configuration.

  Thanks in advance,

  This can help out you.

• Stop/start multiple virtual machines with names created automatically

  Hi all

  in my test environment, I want to stop or start multiple virtual machines via the script.

  Their name is always like this:

  'vm-100-qa', 'vm-101-qa","vm-100-qa","vm-102-qa '...

  Now I would like to just stop every VM 'vm-140-QA' to 'vm-160-qa.

  I created a table "$a = 140.160", but I don't know how to implement this in a script 'Shutdown-VMGuest-comments '.... »

  Sorry for this stupid question. I am a beginner absolute powershell.

  Thank you very much in advance,

  Petrie

  You can do something like this

  140..160 | %{   Shutdown-VMGuest -VM "vm-$_-qa"}
  

• Script to create multiple virtual machines model works is not for the network adapter variable

  We are working on a script to create multiple virtual machines from a template. The script works fine, but when we try to include commands to set the NIC to a group of specific ports on a dvswitch script errors on. Here's what we have so far. This script (less network variables) works, but we would like to include the network configs in the script as well.

  -------------------

  This is the part of the script that configures the network/dvswitch adapter... but does not work properly.

  $myResourcePool = get-ResourcePool-name DQOL

  $dsName = get-Datastore-name "DQOL-DS01.

  $myTemplate = get-Template-name "DQVTemplate".

  $distributedSwitchPortGroup = get-VirtualSwitch-distributed - name "CVE-dvS04-Nexus - k 5 | Get-VirtualPortGroup-name '979-DQ-SHARED '.

  New-VM-name MyVM1-model $myTemplate - Networkname ResourcePool - $myResourcePool - OSCustomizationSpec $mySpecification $distributedSwitchPortGroup - Datastore

  (Get-$dsName data store)

  New-VM-name MyVM2-model $myTemplate - ResourcePool $myResourcePool - OSCustomizationSpec $mySpecification - Datastore (Get-$dsName data store)

  _____________________

  !!!!!!!  This part works, but without specifying a network/dvswitch... card!

  $myResourcePool = get-ResourcePool-name DQOL

  $dsName = get-Datastore-name "CVE-SAN-ISG-DS02-02ef.

  $myTemplate = get-Template-name "DQVTemplate".

  New-VM-name MyVM3-model $myTemplate - ResourcePool $myResourcePool - OSCustomizationSpec $mySpecification - Datastore (Get-$dsName data store)

  New-VM-name MyVM4-model $myTemplate - ResourcePool $myResourcePool - OSCustomizationSpec $mySpecification - Datastore (Get-$dsName data store)

  Here is the error we get:

  New-VM: all parameters can be resolved by using the specified named parameters.

  C:\Users\capuanoj\Desktop\Create-multiplevms-fromtemplate.ps1:6 char: 7

  + New-VM < < < <-name MyVM1-model $myTemplate - Networkname $distributedSwitchPortGroup - ResourcePool

  ePool - OSCustomizationSpec $mySpecification - Datastore (Get-$dsName data store)

  + CategoryInfo: InvalidArgument: (:)) [new-VM], ParameterBindingException)

  + FullyQualifiedErrorId: AmbiguousParameterSet, VMware.VimAutomation.ViCore.Cmdlets.Commands.NewVM

  You cannot use the - model and Networkname - parameters of the cmdlet New - VM in a single order, because both are in different parameter sets. You must first create the virtual machine and then use the cmdlet Set-NetworkAdapter to change the portgroup of the virtual machine. As in example 4, assistance from cmdlet Set-NIC:

  --------------  Example 4 --------------

  C:\PS>$myNetworkAdapters = Get - VM | Get-NetworkAdapter-name "NIC 1.
  $myVDPortGroup = get-VDPortgroup-name MyVDPortGroup
  Together-NetworkAdapter NetworkAdapter - $myNetworkAdapters - $myVDPortGroup Portgroup

  Retrieves all network named "NIC 1" cards of all virtual machines and connects to the specified distributed port group.

• What is the advantage to affect multiple virtual machines in a data store?

  Hello

  Quite a question stupid and basic, but I can't answer . What is the advantage of having multiple virtual machines in a store of VMFS data instead of having each VM in another VMFS data store? (eg. 3 VMs in 1 data store or 3 data warehouses and each virtual machine in one of them). I can only think about the ease of management for storage administrator because it creates only a single large LUN.
  
  Thank you

  By allowing multiple virtual machines in a data store, you can run more than 256 virtual machines in a DRS cluster.

  As a host has a limit of 256 scsi identification numbers, which means that it accesses no more than 255 LUNS shared. 1 scsi ID is used for local storage.

  In a DRS cluster as each host must be mapped to the same data warehouses to ensure that virtual machines can be moved on the cluster and run on any of the hosts.

  Now in my life as an architect VMware PSO I saw that a lot of virtual machines that require a single data store. The main reason to isolate a virtual machine on a data store must provide sufficient i/o performance. This can be achieved with other solutions than to isolate a virtual machine on a data store. Having a properly architected storage subsystem is crucial, vSphere can get out of a very large number of the IOPS / s. With technologies such as SIOC and DRS for storage, you can check that the virtual machines receive IO performance according to the needs.
