Hello,
I want to migrate my oVirt Hypervisors to CentOS7. My strategy is to install new boxes with CentOS7 and add them to the OVirt Cluster. But I get this message in engine.log:
2015-08-07 13:01:35,388 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler_Worker-55) [5b9014cb] Correlation ID: 5b9014cb, Job ID: eddd1466-307f-400e-8d9b-b8cd67c2433c, Call Stack: null, Custom Event ID: -1, Message: Not possible to mix RHEL 6.x and 7.x hosts in one cluster. Tried adding RHEL - 7 - 1.1503.el7.centos.2.8 host to a cluster with RHEL - 6 - 6.el6.centos.12.2 hosts.
I use oVirt Engine Version: 3.5.2.1-1.el6
IIRC recent version also migration between cluster but with warning message. I don't remember if it was in 3.5 or 3.6 but it's doable. There should be some button in migrate dialog which shows more options. j.
