範例
Example 1
Compares virtual machine TestVM and Hyper-V host TestDestinationHost for compatibility.
PS C:\> Compare-VM –Name TestVM –DestinationHost TestDestinationHost
Example 2
Imports a virtual machine whose configuration is not compatible with the Hyper-V host. Note the use of Compare-VM to troubleshoot the import failure in the first step.
Attempts import of a virtual machine; the attempt fails due to incompatibilities with the Hyper-V host.
PS C:\> Import-VM -Path 'D:\vm1\Virtual Machines\53EAE599-4D3B-4923-B173-6AEA29CB7F42.XML'
Gets a compatibility report that describes the attempted import and lists the virtual machine’s incompatibilities with the Hyper-V host.
PS C:\> $report = Compare-VM -Path 'D:\vm1\Virtual Machines\53EAE599-4D3B-4923-B173-6AEA29CB7F42.XML'
Displays the compatibility report, revealing that the virtual network adapter was connected to switch Production. The Hyper-V host has no switch by that name.
PS C:\> $report.Incompatibilities | Format-Table -AutoSize
Disconnects the virtual network adapter.
PS C:\> $report.Incompatibilities[0].Source | Disconnect-VMNetworkAdapter
Generates a new compatibility report to determine if the virtual machine is compatible with the Hyper-V host.
PS C:\> Compare-VM –CompatibilityReport $report
Displays the compatibility report.
PS C:\> $report
Imports the virtual machine.
PS C:\> import-vm -CompatibilityReport $report
