It's centos 6.5. Have I need to change my repo ? I have just EPEL and
Ovirt repo.


Unfortunately we don't have any repo for this yet, only the packages recompiled with such feature enabled available to download in the url that I have provided. We are working with CentOS guys to have an official repo for it.

        Yes it's a live snapshots. Normal snapshot works.


    Question:
    Is it a EL6 hosts? If yes, are you using qemu-kvm from:
    jenkins.ovirt.org/view/__Packaging/job/qemu-kvm-rhev___create_rpms_el6/
    <http://jenkins.ovirt.org/view/Packaging/job/qemu-kvm-rhev_create_rpms_el6/>

      ?


    Thanks!

        mom.conf :

        log: /var/log/vdsm/mom.log

        verbosity: info

        vdsm.conf :

        [root@host02 ~]# cat /etc/vdsm/vdsm.conf
        [addresses]
        management_port = 54321

        attach the
             full log?

             Thanks,
