copied your VHD's to new HDD but cannot start them now ?

[anyweb 478]

Ok imagine this scenario, you run out of hdd space or get a faster hdd that you are storing your HyperV vm's on, and you decide to copy the vms from hd1 to hd2. When you attach the new hd to your computer and try to start your vm's you get an error like this:

 

Unamed VM could not Initialize

 

 

clicking on See Details reveals the following

 

 

'Unnamed VM' could not be read or udpate the virtual machine configuration because access was denied: General access denied error (0x80070005). Check the security settings on the folder in which the virtual machine is stored. (Virtual machine ID 5AE7EC71-5059-4597-9542-86943F192045).

 

 

To fix it we need to restore the ICACLS that were originally set (but not copied) on the VM's. To do this we first need the VM's GUID. To get it, expand the virtual machine dir where you store your vm's, and locate the VM in question, then expand that dir until you see the Virtual Machines directory, in there you'll see the GUID, copy it (the GUID).

 

 

Use the following command

 

icacls “<virtualmachinefolder>” /grant “NT VIRTUAL MACHINE\<virtualmachineguid>”:F /T

 

you'll see it output something like this:-

 

C:\Users\Administrator>icacls "f:\hyperV\vhd\sccm" /grant "NT VIRTUAL MACHINE\5A

E7EC71-5059-4597-9542-86943F192045":F /T
