Network problems was solved after changing Bond mode (and it's strange.
have to investigate around qemu-kvm, cento 7.2 and switch firmware ), but broker problem still exist. If I turn on the host, ha agent start engine vm. When engine VM is up, broker strats to send email. Now I haven't here detailed logs.

My guess is that this is a consequence of your networking problems.

I partially solve the problem.
My host machine has 2 network interfaces with a bond. The bond was configured with mode=4 (802.3ad) and switch was configured in the same way. If I remove one network cable the network become stable. With both
cables
attached the network is instable.
I removed the link aggregation configuration from switch and change the bond in mode=2 (balance-xor). Now the network are stable. The strange thing is that previous configuration worked fine for one year... since the last upgrade.
Now ha-agent don't reboot the hosted-engine anymore, but I receive two emails from brocker evere 2/5 minutes. First a mail with "ovirt-hosted-engine state transition StartState-ReinitializeFSM" and after "ovirt-hosted-engine state transition ReinitializeFSM-EngineStarting"

Hello, I have one testing host (only one host) with self hosted engine and 2
VM
(one linux and one windows).
After upgrade ovirt from 3.6.0 to 3.6.1 the network connection works discontinuously. Every 10 minutes HA agent restart hosted engine VM because result down. But the machine is UP, only the network stop to work for some minutes. I activate global maintenace mode to prevent engine reboot. If I ssh to the hosted engine sometimes the connection work and sometimes no. Using VNC connection to engine I see that sometime VM reach external network and sometimes no. If I do a tcpdump on phisical ethernet interface I don't see any
I packet
when network on vm don't work.
Same thing happens fo others two VM.
Before the upgrade I never had network problems. _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
