I have checked vzctl in a Virtuozzo node and those options are available.. but in OpenVZ there aren't. I have tried adding it to the NETIF param in the VZ config file for the CT.. but don't work: # grep NETIF /etc/vz/conf/3001.conf NETIF="ifname=eth0,mac=00:18:51:28:78:32,host_ifname=veth3001.0,host_mac=00:18:51:00:4F:84,gw=x.y.87.1,ip=x.y.87.48/255.255.255.0" I start the CT: # vzctl --verbose start 3001 Starting VE ... VE is mounted Setting CPU units: 1000 Configure meminfo: 65536 Set hostname: virtual-pxe.example.com Running VE script: /etc/vz/dists/scripts/debian-set_hostname.sh Configure veth devices: veth3001.0 VE start in progress.. # vzctl enter 3001 entered into VE 3001 # ifconfig -a eth0 Link encap:Ethernet HWaddr 00:18:51:28:78:32 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:127.0.0.1 P-t-P:127.0.0.1 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Bridged network is not configured automatically.. Also I have the same problem, when enabling the veth device it does not work, another test: # /etc/init.d/networking stop Deconfiguring network interfaces...done. # route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface # ifconfig eth0 x.y.87.48 netmask 255.255.255.0 up # route add default gw x.y.87.1 eth0 All appears that is OK: # route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface x.y.87.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 x.y.87.1 0.0.0.0 UG 0 0 0 eth0 # ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:18:51:28:78:32 inet addr:x.y.87.48 Bcast:x.y.87.255 Mask:255.255.255.0 inet6 addr: fe80::218:51ff:fe28:7832/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:384 (384.0 b) But I can ping nothing.. I get "Destination Host Unreachable".. something it's wrong :-/ When enabling veth into the CT I need to make anymore in CT0? Thanks! Running Debian Etch (it was a P2V migration) inside the CT.. and CentOS in CT0.
