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 packet
when network on vm don't work.
Same thing happens fo others two VM.
Before the upgrade I never had network problems.
6:51 p.m.
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"

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

Stefano,
I am currently experiencing the same issue. 2x nic lacp config at switch, mode 4 bond at
server with no connectivity. Interestingly I am able to ping the switch itself.
I haven't had time to investigate thoroughly but my first thought is an update
somewhere.
Did you ever resolve and get back to mode=4?
Jon
