@F-Bosch: Regarding the link going down I experienced that too. I correlated it with IPv6. When I disabled IPv6 on the interface the problem went away. Previously the more data I sent over ipv6 the sooner it broke. No logs whatsoever. Migrating the machine to another host restored the connectivity without rebooting the guest.
