[fedora-virt] [OT] info on debugging migration

[Gianluca Cecchi]

Hello,
sorry for the off-topic, but since rh el6 is a sort of F12 and its
cluster is based on stable3 as in Fedora 14... it can be of some
interest for others..
I have two rh el 6 systems configured with rhcs and clvmd.
general cluster services seems to be ok.
As I'm not able to successfully migrate a vm through clusvcadm, I'm
now downsizing the problem to direct virsh command that fails when
called from clusvcadm.
I have also ssh equivalence in place (for the intracluster names) so
that I can run from host2:

[host2 ] # virsh -c  qemu+ssh://intrarhev1/system list

without need of password input.

But when I try:

# virsh migrate --live exorapr1 qemu+ssh://intrarhev1/system
I receive:
error: operation failed: Migration unexpectedly failed

On host2:
[host2 ] # virsh list
 Id Name                 State
----------------------------------
  3 exorapr1             running

In messages:
Mar  4 14:27:30 host2 libvirtd: 14:27:30.527: error :
qemuDomainWaitForMigrationComplete:5394 : operation failed: Migration
unexpectedly failed

Setting this:
[root at host2 libvirt]# export LIBVIRT_DEBUG=1
[root at host2 libvirt]# export LIBVIRT_LOG_OUTPUTS="1:file:/tmp/virsh.log"

I get the file I'm going to attach (due to migration happening with
intracluster network, the names are intrarhev1 and intrarhev2 on that
LAN)

It seems no more information in the file....
Any hints on further debug, apart opening an official case?

Thanks in advance,
Gianluca
