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

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"
