Update:

There was windows patching of the VM occurring at the time of the issue. The Virtual Disk Service was flickering between stopped and started. I "guess" this could cause an issue if it was flicking between started and stopped when sql was trying to write to the tran log on a LUN controlled by the Virtual Disk Service.

Scans of the disks within the VM VHD's and physical storage have shown no issues. No corruption since the issue also.

Im inclined to think patching caused this issue, but am still looking for hard evidence.
