Virtual Machine hosted on HYPER-V shows status "saving" and restarts at times.
Posted on 2015-01-05
I just inherited HYPER-V host that has only 1 Virtual Machine on it.
The Host's OS is Windows 2008 R2.
The VM's OS is Server 2012 R2.
It seems that the VM is at times becoming "unavailable" and when I check the "Hyper-V Manager" it shows "saving" status.
It happened few times now - at first I thought that I must have initiated the "Saving" by mistake, but now I was able to observe it while it happened.
I do not know how often if happens, but it seems to be happening in "after business hours" time frame - It happened today around 7PM - I will try to observe if it will happen again at the same time.
The VM went into "saving" status and eventually "restored" itself.
I have not seen this behaviour on other HYPER-V hosts, and I wonder if the previous IT stuff had set-up some kind of scheduled task, possibly for backup purposes as they did not have proper backup software before.
I can't find any traces of the scheduled task, and wonder if someone can give me some pointers?
