The VMs are kept on a 5-disk RAID6. It's this RAID6 that gets the workout when the VM gets busy. If you can the messages that you're concerned about then I can check for anything similar here. I'm currently running 3 VMs. Note that if it is a RAID issue that it might not be an mdraid problem but rather the actual disk drive not being up to the tasks it needs to perform. I have a bunch of 1TB WD Green drives on my bookshelf due to RAID problems. I replaced them with WD RAID Edition drives and haven't seen a problem since. HTH, Mark
