I guess you're hitting the primary/secondary network issue, but as you didn't provide much information (kernel/tools version, network configuration of the vservers) and my crystal ball is broken, I can't tell anything else ;) For the primary/secondary stuff: In Linux, for each subnet there is one primary address. If this address is removed, all secondaries are removed, too. Example, I assume that there are no addresses from 10.0.0.0/8 configured yet: ifconfig eth0:0 10.0.0.1 <-- becomes primary ifconfig eth0:1 10.0.0.2 <-- becomes secondary ifconfig eth0:2 10.0.0.3 <-- becomes secondary ifconfig eth0:3 10.0.0.4 <-- becomes secondary ifconfig eth0:2 down --- eth0:2 is gone now ifconfig eht0:0 down --- eth0:0 _and_ eth0:1 and eth0:3 are gone now So if you have addresses from the same subnet in different vservers, and of the vservers 'owns' the primary address, stopping/restarting that vserver will causes the other vserver to lose their addresses. Work-Arounds: Either reserve an ip address in the used subnets that is statically configured on the host and being the primary one (i.e. the first address from that subnet), so the primary address will never be removed. Or use /32 addresses, that way, the subnet contains only a single address and thus there can't be any secondaries.
