Hyper-V cannot mount VHD - The storage where the virtual hard disk is located does not support virtual hard disk sharing.

Hi there,

I have an Ubuntu running about 15 months on Hyper-V when suddenly its stops working, saying "The storage where the virtual hard disk is located does not support virtual hard disk sharing.".

So, I deleted the VM and VHDs, removed Hyper-V, added again. Removed all config files under ""C:\ProgramData\Microsoft\Windows\Hyper-V". But the problems stills. I don't use clustered servers and have nothing related installed.

Tried to create just a simple VM, but the error persists.
