After that and a RHEV-M reboot all, VM's went in unkown state, all hosts (RHEV-H), storage domains, clusters, datacenters went in Non Responsive.
Lots of errors in engine.log, like

2015-01-21 21:55:25,414 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesVDSCommand] (DefaultQuartzScheduler_Worker-31) Command GetCapabilitiesVDSCommand(HostName = rhevbohnw01.unix.regionh.top.local, HostId = 4256f307-fbab-4ae7-bdf0-7025d1ecf007, vds=Host[rhevbohnw01.unix.regionh.top.local,4256f307-fbab-4ae7-bdf0-7025d1ecf007]) execution failed. Exception: VDSNetworkException: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

One per Host.

Decided to do a yum undo and without reboot everything is fine again.

Did the same yum update on another environment also with same versions RHEV-M and RHEV-H. Exact same issue here where undo also corrected the problem.

Anybody experienced the same??
