Meanwhile I tested a bit more and found out that there are 3 of 8
systems involved. One backup system and two production systems.
Everytime time if I shutdown the backup system (normally every midnight
to reset the snapshots for backup) the both other systems looses
their network interface. If I shutdown the systems to restart them, I
get "RTNETLINK answers: Cannot assign requested address" error. After
restart everything is fine.

Our setup:
single amd64 with 2GB ram
2 300GB hdd running as softraid 1 with lvm2 and evms
latest gentoo vserver
all guests have own internet ip's and are running on a evms volumes with
snapshot feature for backup purposes

I tested this and all guests have only their designated addresses bound,
so this shouldn't be the cause here. I don't know the
"primary/secondary propagation", but I guess I don't need it in this
scenario.
Does anyone have a suggestion with these additional infos?
Thanks in advance
Martin
