Hello Chris,
Steps taken to test the proposed package:
1) enabled trusty-proposed
2) installed qemu-system-arm qemu-system-common qemu-system-misc
qemu-system-x86 qemu-user version 2.0.0+dfsg-2ubuntu1.25
3) again on a second trusty14.04 server
4) migrate 41 running VM's (uptimes vary between 1
We have four identical Ubuntu servers running libvirt/kvm/qemu, with
access to CEPH rbd filesystems. Guests can be live migrated between
them. However, live migration leads in ~30% of the cases to guests being
stuck at 100%. Only a few times we had the patience to wait, and upon
logging in our
I can reasonably assume that this solved my problem. I've live migrated
41 VM's 5 times between 2 hypervisors without the 100% cpu problem
appearing.
My production servers run 2.0.0+dfsg-2ubuntu1.22, and still observe the

Attached is the patch that I created with quilt in

@serge,
I'd be happy to test each of the patches, but considering the length of
this page I'd like an exact link to a patch and/or patches that need to
be tested, and against which version (trusty-security i suppose?).
