Comment 15 for bug 1449687

Please backport qemu 2.10+ and libvirt 3.6+. Having issues with migration of thin provisioned disks without shared storage. Tried qcow/raw/lvm thin all with the same results. Can confirm that the versions from https://launchpad.net/~ubuntu-cloud-archive/+archive/ubuntu/pike-staging do fix the issues at least with qcow disks.
