I was able to reset the power state, but when I wanted to start it on the remaining host, it returned an error:

SR_BACKEND_FAILURE_46(, The VDI is not available [opterr=['HOST_OFFLINE', 'OpaqueRef:34e590d8-19ab-eb89-af81-5eead08952d1']], )

Apparently there were still locks on the disk, so I looked up the uuid and removed it from the pool database

xe vdi-forget uuid=....

Next I gave it a new name, attached it to the VM and was able to restart the VM.
Thanks for pointing me in the right direction !

HI,

I have 2 host in a pool with VMs distributed amongst them. Today first the NICs in one host (not the pool master) died and then the entire server became unstable (not always booting, but when it boots, it doesn't have any NIC).

The problem is that I cannot migrate the VMs which running on that host or even restart the VMs again on the pool host because it thinks they are still running.
The VM disks are on shared storage.

How can I get these VMs to start on the pool master?

thanks
Hans
