[ovirt-users] Host fencing issues

Wed Oct 18 05:09:03 UTC 2017

Ok I have not collected data yet...
I figure I upgraded my engine to the latest revision of the 4.0 branch
and I did... It actually fix nothing... No matter what I do the hosts
continue to experience the same issue.... Is this a known problem in the
4.0 branch with CentOS7?
I will collect data as soon as I get a chance...

On another note... I was able to bring online a host using the ovirt 4.0
node image, I experience other issues though... I cant seem to migrate
VM's out from the node.... I can migrate VM's in but not out... As if
the node is not compatible with the rest of the hosts which run Centos 7
x86_64... Is this hunch correct? can ovirt node work along side with
Centos7 hosts?
Thoughts and ideas?
