Hi James, everyone,
When debugging things, I already came across this bug. It is unlikely to
be the cause of our issues:
Firstly, we migrated from 3.4.0 to 3.4.1, so we already had the possible
port number conflict, but things worked fine with 3.4.0.
Secondly, I don't see the 'address already in use' messages in my
logfiles (see the qemu logfiles I posted).
Also, the migration itself doesn't fail: it works fine, the guest ends
up on the other server, it's just that the migrated guest loses
read/write access to its filesystem.
Regards, Paul Boven.

Not sure if it's related at all, but is there any chance this has
anything to do with:

It came to mind as something to do with glusterfs+libvirt+migration.
HTH,

I experienced a strange behavior of glusterfs during livemigration
of a qemu-kvm guest
using a 10GB file on a mirrored gluster 3.4.2 volume
(both on ubuntu 13.04)
I run
virsh migrate --verbose --live --unsafe --p2p --domain atom01
--desturi qemu+ssh://<target_ip>/system
and the migration works,
the running machine is pingable and keeps sending pings.
nevertheless, when I let the machine touch a file during migration
it stops, complaining that it's filesystem is read only (from that
moment that
migration finished)
A reboot from inside the machine failes,
machine goes down and comes up with an error
unable to write to sector xxxxxx on hd0
(than falling into the initrd).
a
virsh destroy VM && virsh start VM
leads to a perfect running VM again,
no matter on which of the two hosts I start the machine
anybody better experience with livemigration?
any hint on a procedure how to debug that?
TIA
Bernhard
