KB2666703 – Cannot Restore A VM That Has A Semicolon In Name Or Directory Path On A Windows Server 2008 R2 SP1

Microsoft has just released a hotfix for people running W2008 R2 Hyper-V where they cannot restore a VM that has a ; in it’s name or folder path.

“If the name or the directory path of a virtual machine contains a semicolon (;) on a server that is running Windows Server 2008 R2 Service Pack 1 (SP1), you cannot restore the virtual machine.

This issue occurs because the Hyper-V Volume Shadow Copy Service (VSS) writer incorrectly parses the configuration information in the backup metadata document of the virtual machine if the configuration information contains a semicolon”.

A supported hotfix is available from Microsoft.
