VM stuck in a failing Host

[Jaime Orlando Rojas Sanchez <ja...@kumo.com.co>]

Hello,

We have a 4.2.1 ACS, running on XenServer 6.2.0, we have a zone with a pool of 3 host, yesterday 1 host crash and OS get corrupted. I think we lost that host and have to reinstall it, but the issue is that we had a couple of VM and VR running on that host. The failing host  was the master of the pool, so once it fails all the pool was disconnected, we change the master role and recover pool management from Xencenter and ACS, once we did it a VM moved to the remaining host, all VR and 1 VM kept stuck in failing host.

In DB we see the VR and VM running, even if the host was marked as down and maintenance. We changed the VR state to 'stopped' and change de "last host ID" and "Host ID" to a working host. Once we did it we were able to destroy the VR and recreate them with successful results, they came up on working host. If we change only the state, the VR couldn't be destroyed. Here we workaround with the 70% of the outage, BUT one VM remain stuck to the host, we change the state, the last host ID, but once we press start, it "runs" on the failing host and the VM appears as running even if it doesn't. Any suggestion to force the VM to start in a different host and remove it from the failing host? This is a critical VM, we hope somebody else could give us a hand.
