Reverting to VM snapshot for multiple VMs

Question

#Connect-VIServer 10.222.111.21 –User root –Password Welcome2world

$VMs = Get-Content 'C:\vmscripts\vmlist.txt'

$snapname = 'BaseOS'

Get-Snapshot -VM $VMs -Name $snapname | Foreach-Object {  Set-VM -VM $_.VM -Confirm:$false }

The above script works fine as VM-snapshot exists. But it fails if any one of the VM's does NOT have the snapshot "BaseOs'.

Can someone help please! The platform is VMWARE.

That is just how vMware Get-Snapshot cmd-let works. If you specify -Name parameter of snapshot and -VM as multiple hosts, it will fail if some of these hosts doe snot have the snapshot specified in -Name parameter. This will work: Add some logic to your command to go through each $VM and if snapshot name equals $snapname, revert then. This will work:

$VMs = Get-Content 'C:\vmscripts\vmlist.txt'
$snapname = 'BaseOS';
foreach($VM in $VMs) { Get-Snapshot -VM $VM | Foreach-Object { if($_.Name -eq $snapname) { Set-VM -VM $VM -SnapShot $snapname -Confirm:$false } } }
