I wanted to perform some long overdue maintenance on a hyper-v host. My setup is two Win2008 R2 Core Hyper-V machines with local disk storage (no san, no virus protection on the hosts). I powered down the Guest OS's, exported them from Virtual1 and copied the to Virtual2. The guest OS came up and worked no problem on Virtual2. Later on in the day I powered down Virtual2. When virtual2 came back up 2 of the 3 guest VM's have disappeared from the management console.
Some items of note...
- There is no virus protection running on the hosts (others seem to have been having an issue with virus scanning).
- Event logs show the orderly shutdown of the guest VM's, event logs then show only 1 of the machines turning back on.
- I see no useful errors in the event logs related to starting the machines back up
- There is a single event log entry for "Hyper-v failed creating a new partition (status 11)". Although, there is plenty of free RAM & Disk space
Anyone have any idea what's going on? I'm kind of baffled as where to even begin looking.
Thanks for any help,
