Hello.

i've a proxmox server, in system tab, i just have one interface named vmbr0 that configured with main server ips , gateway and netmask.
everything is ok and i'm using it for more than 1 year.

i just bought a new server, i just installed proxmox on it.
in system > interfaces , i have 3 interfaces
eth0 is configured automaticly with main server ip.
eth1 is not cofigured and it's inactive
also vmbr0 is not configured and inactive.

i create a openvz vm and give it an ip.
but it cannot start :
Code:
/usr/sbin/vzctl start 101
Starting container ...
Container is mounted
Adding IP address(es): 85.17.21.178
RTNETLINK answers: Network is down
vps-net_add ERROR: Unable to add route /sbin/ip route add 85.17.21.178 dev venet0 
Container start failed
Stopping container ...
Container was stopped
Container is unmounted
VM 101 start failed -

any solution please?

Hi,
in the default proxmox-installation eth0 has no ip-address and is used at the bridge vmbr0. vmbr0 has the ip-address of the node.

With this configuration your VMs are able to use virtuall devices on the same bridge to use ip adresses in the ip-range of vmbr0.
