I saw this in the vdsm logs:

MainThread::DEBUG::2014-11-27 15:48:04,660::libvirtconnection::143::root::(wrapper) Unknown libvirterror: ecode: 43 edom: 19 level: 2 message: Network not found: no network with matching name 'vdsm-rhevm'

Dan, could this lead to connection issues?

This bug can't reproduce every time. I try it as the following steps. it can't reproduce now.
1. when rhevh in non-responsive status,the bug can't reproduce after reboot it, rhevh can register to rhevm server successfully. 
2. Reinstall the rhev-hypervisor7-7.0-20141119.0.el7ev on the same machine which occurred this problem, then registered it to rhevm-3.5.0-0.21.el6ev.noarch, it's success to register it to rhevm. 
3.Install the same rhevh on another two machines, then register it to rhevm3.5. it also can't reproduce.

I don't think so. this log noise looks much more like

 bug 1121571 	annoying false error when starting vdsmd

Could you share connectivity.log from the host?

Comment 10 Petr Kubica 2014-11-28 14:50:38 UTC
I cannot reproduce with my step now, thought yesterday it happen to me with two rhev-h 7.0 machine. Now it seems, that everything working correctly with no error.
