In OpenVZ case you _must_ to decide what name the interface will have inside the container. The command line for ading an interface in OpenVZ looks like # vzctl set $veid --ifname_add ifname[mac, host_ifname, host_mac] The only mandatory field is the name of _container interface_ The possible solution is the following: * absolutely ignore the <target dev=".."> in openvz XML description * Set (ifname, host_ifname) of the interface to (eth${N}, veth${ID}.${N}), where ID is the container id and N is the interface number within that container. It is simplifies saving the bridge name and adding the interface to the bridge too, for example, by adding the following line to the $veid.conf: #BRIDGE$N: <name of bridge for interface # $N > > > We only care about configuration from the host side. > > > Daniel > -- > |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/:| > |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org:| > |: http://autobuild.org -o- > http://search.cpan.org/~danberr/<http://search.cpan.org/%7Edanberr/>:| > |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 > :| >
