XenServer VM unable to start
Posted on 2013-10-26
I've got an interesting one here...
Client has a XenServer to run a temporary Server 2008 VM - they had some server troubles and this has been set up for them for temporary use.
It's been set up with a C: of 250GB and a D: of 750GB.
So it's been running fine for a while now (few months actually - they've taken theior sweet time in deciding how they want to continue). They have a load of data stored on this VM, yesterday the physical machine was restarted (I was not party to this) and there was an error about the storage not being attached.
This is odd, because the XenServer is a single HP Proliant ML110 G4 using internal storage - all hdd's appear to be ok and running.
I connected to the pc that XenCenter is running on, started the VM and it started ok - the guy onsite said that the SR mysteriously reconnected when I logged on to the management pc...
So with the VM booting, I thought this was the end of it.
Except that the VM seems to have been starting up since then. It spent probably 20 hours on the 'Waiting for the local service manager' screen.
Having seen something like this previously on a physical 2008 server which was caused by IP settings that disappeared, I figured I'd bounce the VM, start it in Safe Mode, check the IP settings and troubleshoot further if that did not help.
Problem: VM now won't start.
Trying to start it in XenCenter gives 'the SR failed to complete the operation'.
Is there any way to fix this?
Alternatively, is there any way to get the D: data out?
Moving the VHD or something to that effect?
