Taking/Restoring live snapshots (test windows VM) is taking a
ridiculous amount of time - unusably so.
With images hosted on our NAS (NFS) or on gluster, snapshots take
around 30 seconds to take and/or restore.
- 9 *minutes* to take
- The restore has take *20 minutes* to get to 34%
And it generating iowait's of around 15%
Same hardware and VM's as previous tests, just different underlying storage.
Snapshots of a shutdown VM are near instant.
