Indeed I see the same behaviour:<br>
When a guest is running, it is owned by libvirt:kvm on both servers.<br>
When a guest is stopped, it is owned by root:root on both servers.<br>
In a failed migration, the ownership changes to root:root.<br>
<br>
I'm not convinced though that it is a simple unix permission problem, because after a failed migration, the guest.raw image is completely unreadable on the destination machine, even for root (permission denied), whereas I can still read it fine (e.g. dd or md5sum) on the originating server.<br>

Hi Paul,<br>
thnx, nice report,<br>
u file(d) the bug?<br>
can u do a<br>
watch tree - pfungiA <path to ur vm images pool><br>
on both hosts<br>
some vm running, some stopped.<br>
start a machine<br>
trigger the migration<br>
at some point, the ownership of the vmimage.file flips from<br>
libvirtd (running machnie) to root (normal permission, but only when stopped).<br>
If the ownership/permission flips that way,<br>
libvirtd on the reciving side<br>
can't write that file ...<br>
does group/acl permission flip likewise?<br>
Regards<br>
Bernhard<br>

Hi Bernhard,<br>
<br>
I'm having exactly the same problem on Ubuntu 13.04 with the 3.4.1 packages from semiosis. It worked fine with glusterfs-3.4.0.<br>
<br>
We've been trying to debug this on the list, but haven't found the smoking gun yet.<br>
<br>
Please have a look at the URL below, and see if it matches what you are experiencing?<br>

I had/have problems with live-migrating a virtual machine on a 2sided<br>
replica volume.<br>
<br>
I run ubuntu 13.04 and gluster 3.4.2 from semiosis<br>
<br>
<br>
with network.remote-dio to enable I can use "cache mode = none" as<br>
performance option for the virtual disks,<br>
<br>
so live migration works without "--unsafe"<br>
<br>
I'm triggering the migration now through the "Virtual Machine Manager" as an<br>
<br>
unprivileged user which is group member of libvirtd.<br>
<br>
<br>
After migration the disks become read-only because<br>
<br>
on migration the disk files changes ownership from<br>
<br>
libvirt-qemu to root<br>
<br>
<br>
What am I missing?<br>
<br>
<br>
TIA<br>
<br>
