Hi everyone I have been using node el6 with fiber channel multipathing and multiple NICS. Works fine. Obviously after 3.6.1 or .2 is out I will want to upgrade. How well do the nodes handle upgrading from el6 to el7? Has anyone done this? Thanks, Chuck

I haven't upgraded my centos 6.6 nodes, only tried to add a centos 7 node and as for oVirt 3.5.1 you can't mix el6 and el7 in the same cluster. I don't know if this will change in a next oVirt release.

Hi Chuck,

Hi, I'm using oVirt 3.5.1 and here is what I did : in a cluster with CentOS 6.6 hosts, I added a brand new CentOS 7.0 host and when adding it to the cluster, oVirt refused to add it because mixing 6.x and 7.x was not allowed. I had to create a second cluster in the same DC, and put my new 7.x host into this second cluster. What I'm doing at present is progressively upgrade each host and move them into the next 7.x cluster. Please note that migrating VM between 6.x and 7.x hosts is limited along what is described in the following BZ : https://bugzilla.redhat.com/show_bug.cgi?id=1150191 Best regards, -- Nicolas ECARNOT
