At linux-vserver has bug with selected source address for outgoning packets.
It bug exist because not divided routed cache info per context.
routing informations about sending packets be stored in routing cache
(net/ipv4/route.c; /proc/net/rt_cache) and it`s info be used before any call
its can be tested simple:
1) assign to vps address from network other then host system.
2) send any packet from vps to any host in that network.
3) try to send packet from host system to selected host.
packet been have vps source address.

Simple fix for it - add context tag at rt_key structure. more correctly - full
separate it`s cache.

With best regards,
