| Doc Text: |
Previously, the virtual machine's "mirror" and "mirrorPath" properties had a value of "None" rather than an empty string. This caused problems when restoring virtual machines from suspended states. The "mirror" and "mirrorPath" properties are now correctly set to empty strings, and this issue no longer causes the failure of virtual machines to restore from suspended states.
