Thanks Markus, but I have a single, self-hosted node, so cannot migrate VMs.
Is it your assumption that F20 will never be updated with libvirt 1.2.9?
If that's the case, my best course (in a month or so when F21 is
released) is probably to export all my VMs, install F21,
reinstall/reconfigure oVirt, import the old Export Domain, and then
import my VMs again.

Hi Bob,
if your are on a cluster with FC20 hypervisor nodes wthout virt-preview
(like we run it with qemu 1.6.2) the simplest way to get live merge features
should be - beware NOT FULLY TESTED!
1) choose a single host (we only need a single one if we think about the required setup)
2) Install libvirt from virt-preview repos. DON'T UPDATE QEMU AS YOU BREAK LIVE
MIGRATION!
3) migrate VMs you want to live merge to the host
4) do the live merge
5) migrate VMs back to original host
A quick test revealed:
# systemctl stop vdsmd
# systemctl stop libvirtd
# cd /etc/yum.repos.d
# wget http:/wget
http://fedorapeople.org/groups/virt/virt-preview/fedora-virt-preview.repo
# yum update libvirt
...
# systemctl start libvirtd
# systemctl start vdsmd
#
# vdsClient -s 0 getVdsCaps | grep -i merge
---> liveMerge = 'true'
Best regards.
Markus

Thanks!
Would you know how one could track to see if there is a plan for e,g.
Fedora 20 to include that version at some point? I suspect every distro
is different. F20 at this point includes 1.1.3. I'd like to know if I'll
have to upgrade to Fedora 21 in order to get this functionality, as this
will require some planning on my part.
Thanks again,
Bob
