Hello Rohit,
No issue for migration in my test environment (KVM over KVM) with the
4.5.2 RC1 on Ubuntu 10.04.3 (up to date)
AppArmor is disabled for libvirtd and virt-aa-helper
(see my ansible script:
https://github.com/milamberspace/ansible-cloudstack-ubuntu-aio/blob/master/roles/cloudstack-node/tasks/libvirtd.yml)

Hi all,
I’ve been testing a bug on KVM which involves VM migration, and in that
process I found that VM migrations failed in my environment twice even
with clean setups of Ubuntu 14.04.3 (lastest and updated packages) based
KVM hosts against CloudStack 4.5.2-SNAPSHOT (latest 4.5).
We haven't seen issue with migrations in production, but I'd have to
look more closely.
I wanted to share this issue to confirm if this is just my environment
or if someone experienced similar issue with latest Ubuntu 14.04 based
KVM hosts.
The specific errors I found in the logs were something like
"qemuMigrationCancelDriveMirror:1421 : Unable to stop block job”, which
are likely reproduced by others such as:
https://www.redhat.com/archives/libvirt-users/2014-June/msg00057.html
http://lists.nongnu.org/archive/html/qemu-devel/2014-12/msg03093.html
A possible solution could be to download libvirt to 1.1.x.
Have you disabled AppArmor on that machine? We've seen many machines
with random weird issues when AppArmor was enabled.
