[ovirt-users] VM migration failed after upgrade to 4.4

[joris dedieu]

Hi list,
I'm troubleshooting an issue with live migration on an upgrade context.
I have a 4.3 cluster that I try to upgrade in 4.4. The engine is OK in
4.4  and I already have upgraded a single host which had kindly
reintegrated the cluster.

The host is OK. I can start vms on it and migrate vms from it to other hosts.

But, if I try to migrate a vm from a 4.3 host to the 4.4 host, it failed with :

* on the host :  qemu-kvm: terminating on signal 15 from pid 
()
* on the engine : VM 'VM_UUID' was unexpectedly detected as 'Down' on
VDS 'HOST_UUID'

Does anyone here can help me to find what's goning on ? I will be greate

regards
Joris

Where/when was the VM started. Did you upgrade anything while VM was running?

Are they same versions?

[ovirt-users] VM Migration Failed

[Michael Watters]

I am running ovirt 3.6 on our cluster and VM migration is failing.  The
VDSM logs show an error as follows.

jsonrpc.Executor/7::ERROR::2016-12-16 
08:41:04,398::vm::4714::virt.vm::(_updateDevicesDomxmlCache) 
vmId=`dc419d2b-522a-4e96-b06a-243ec8ede44e`::Alias not found for device type 
redir during migration at destination host

Does anybody know what would cause this?  Both hosts are online and have VMs 
running.
