[ovirt-users] Cannot clone a snapshot

Mon Oct 30 22:17:53 UTC 2017

I have a Radeon HD 6870 that I have passed through to a Windows 10 host.  I
decided to build 2 servers using Xeon-D 1528 processors (Super Micro
x10sdv-6c+) in a very small Node 304 mITX form factor. I didnt want a third
box as a desktop, so I have a "desktop" that is actually a Windows 10 guest.
