Hi guys,

I had a strange issue on the 3rd of September and I've only got round to checking what caused it now. Basically about 4 or 5 Windows Server VM's got completely corrupted. When I press start I'd just get a blank screen and nothing would display, I tried various things but no matter what I wouldn't even get the Seabios display showing the VM was even posting

The remaining 10 VM's were fine, it was just these 4 or 5 that got corrupted and to recover I had to do a full DR restore of the VM's.

I'm concerned that the issue might appear again, which is why I'm mailing the list now, does anyone have any clues as to what might have caused this? All logs on the FC SAN were fine and all hosts appeared normal...

The following are my versions...
