hi stefan,
it seems that's more stable but after 2 minute the issue is back again.
hopefully isn't a bug because it can reproduce it

you have to disable all offloading features (rx, tx, tso...)

@jan and stefan
must i set it for both bridges
eth1 (br1) eth0 (br0) on the host or guest ?

Beo,
do you experiencing cluster split? If answer is no, then you don't need
to do anything. Maybe network buffer is just filled. But, if answer is yes,
try reduce mtu size (netmtu in configuration) to value like 1000.
Regards,
Honza
