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. -Bob On 11/20/2014 01:20 PM, Markus Stockhausen wrote:
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.

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

Are there any bugs related to the changes in question that we can track so we know when the changes are reflected in our distros of interest?
Thanks, Bob

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
Hello, following the flow, as I have now an all-in-one environment based on F20 and oVirt 3.5. As it is both my engine and my hypervisor, I should be in the best situation.... live merge is supposed to be supported on file based storage, that should match what I have (local on Host). In fact, installing oVirt AIO on F20 automatically gives the virt-preview repo through the ovirt-3.5-dependencies.repo file and I see: [root@tekkaman qemu]# rpm -q libvirt libvirt-1.2.9.1-1.fc20.x86_64 [root@tekkaman qemu]# vdsClient -s 0 getVdsCaps | grep -i merge liveMerge = 'true' [root@tekkaman qemu]# rpm -q qemu qemu-1.6.2-10.fc20.x86_64 Created a CentOS 7 x86_64 VM with a VirtIO-SCSI disk and after install I powered off and run it normally. Then I took a snapshot (while VM powered on) and then ran a yum update. At the end I reboot the VM with the new kernel installed and tried to delete the snapshot and the task indeed started: Snapshot 'test per live merge' deletion for VM 'c7' was initiated by admin. but about a minute later I got error: Failed to delete snapshot 'test per live merge' for VM 'c7'. here below relevant parts in log files. What did I miss in the workflow? BTW: both during the live snapshot and during the live merge I got disconnected both from spice console and from an ssh session open into VM (I could reconnect on both): is this expected? I hope not so..

OK, I reply to myself The error above is explanatory... I didn't notice that only the libvirt part is included in the ovirt-3.5-fedora-virt-preview repo: " [ovirt-3.5-fedora-virt-preview] name=Virtualization packages from Rawhide built for latest Fedora baseurl= http://fedorapeople.org/groups/virt/virt-preview/fedora-$releasever/$basearc... enabled=1 skip_if_unavailable=1 gpgcheck=0 includepkgs=libvirt* " SO I think I need qemu-2.1.2-6.fc20.x86_64.rpm and probably other packages as provided by virt-preview. What could be the safest way to include further qemu packages? How stable is qemu 2.1.2 at this time? Thanks, Gianluca
