Q. How can I easily import a number of VMs from a folder structure and automatically fix any core problems such as wrong switch name or more cores than supported on the system?
A. The script below will import all VMs found in a folder path and will automatically fix the switch to a new switch it creates (you could change this to use an existing switch you have) and also solves and issues if the VM has more cores than supported on the box by changing to 4.
import-module hyper-v $VMRootPath = 'C:Workshop'New-VMSwitch -Name "InternalSwitch" ` -SwitchType Internal$VMXMLFiles = Get-ChildItem -recurse $VMrootPath*.xmlforeach($VMXMLFile in $VMXMLFiles){ #Import will fail as switch name is different $report = Compare-VM -Path $VMXMLFile foreach($incompatibility in $report.Incompatibilities) { if($incompatibility.MessageId -eq '33012') #Switch problem { Write-Output "Binding to different VMSwitch" $incompatibility.Source | Connect-VMNetworkAdapter -SwitchName "InternalSwitch" } if($incompatibility.MessageId -eq '25014') #Cannot restore saved state { Write-Output "Removing saved state" $Report.VM | Remove-VMSavedState } if($incompatibility.MessageId -eq '14420') #Too many cores { Write-Output "Changing number of cores to 4" $Report.VM | Remove-VMSavedState #Need to remove saved state to change cores $Report.VM | Set-VM -ProcessorCount 4 } } $newvm = import-vm -CompatibilityReport $report start-vm -VM $newvm}
