I have a Hyper-V server which has served me well, so far. It's been in a workgroup until recently, and has hosted four machines. I hadn't used it for a while and decided to join it to my new domain. I also had to apply a load of patches.
Now, I'm trying to create a new machine. I've already created the hard disk and when I try to create the VM I'm getting a window which says:
The server encountered an error while creating DomainSql1.
The operation failed.
Failed to create external configuration store at 'D:\Hyper-V': General access denied error (Virtual machine ID 0x80070005)
and in the event log:
Log Name: Microsoft-Windows-Hyper-V-VMMS-Admin
Date: 22/07/2012 06:53:09
Event ID: 13000
Task Category: None
Description: User 'DOMAIN\Administrator' failed to create external configuration store at 'D:\Hyper-V': General access denied error (Virtual machine ID 0x80070005)
I've had a search and found one problem which mentions symbolic links but that doesn't seem to apply to me as I can see the symbolic link in "C:\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines" and the folder path its pointing to get created at "D:\Hyper-V Domain\DomainSQL1\Virtual Machines" but it's empty - no XML file is created. The Virtual Machines identity has the following permissions on the Virtual Machines folder:
