do you have an eth4 on your host?

[sxf]:yes, there are five network interface cards in my server.

that's simply wrong ... use 255.255.255.0 for mask, or prefix for 24

[sxf]:it is a clerical error. It is not "mask" but "prefix", so the configuration is: echo "24" >
 /etc/vservers/xxx/interfaces/0/prefix
