[Vserver] host - guest network interface interaction oddity
I have situation I'm not sure I am interpreting correctly. The problem is that restarting a guest on a host (both Debian 2.6.15, default vserver capabilities) somehow manages to bring down one interface of the host as well, but only _on guest restart_, I cannot down the interface from inside the guest (which is as is should be). I have two addresses on the same subnet (one is a failover address) on the same card. ifconfig on the host gives: eth0 Link encap:Ethernet HWaddr 00:E0:81:27:C6:A6 inet addr:94.152.112.53 Bcast:94.152.112.255 Mask:255.255.255.0 RX bytes:1444026448 (1.3 GiB) TX bytes:1549809611 (1.4 GiB) Base address:0xc000 Memory:f200-f202 eth0:0Link encap:Ethernet HWaddr 00:E0:81:27:C6:A6 inet addr:94.152.112.55 Bcast:94.152.112.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Base address:0xc000 Memory:f200-f202 eth1 Link encap:Ethernet HWaddr 00:E0:81:27:C6:A7 inet addr:10.10.10.53 Bcast:10.10.10.255 Mask:255.255.255.0 ifconfig on the guest (as it is and should be): eth0 Link encap:Ethernet HWaddr 00:E0:81:27:C6:A6 inet addr:94.152.112.53 Bcast:94.152.112.255 Mask:255.255.255.0 guest:/# ifconfig eth0:0 down SIOCSIFFLAGS: Permission denied when I do a vserver guest restart on the host I get the following host:~# vserver guest restart Stopping periodic command scheduler: cron.

Re: [Vserver] Problem binding to 0.0.0.0
This is strange. Normally, a vserver is bound to one IP address and even a bind to 0.0.0.0 should be mapped to this single IP address. Agreed, we've been runnning vservers since v0.3 and never had a problem like this. What's the result of a netstat -tpln and chcontext --xid 1 netstat -tpln executed on the host (perhaps before and after starting httpd on the guest) ? Doesn't seem to suggest anything odd taht I can see.
