Hi,

i wanted to ask wether there is a possibility to rename venet0 to eth0, because confixx does only work, when an interface named eth0 is present.
(Or maybe i can create a fake interface in the VM?)

i did vzctl set 107 --veth_add veth107.0,00:0C:29:D9:F7:6D,eth0,00:0C:29:D9:F7:6C --save
it said
Processing veth devices
Saved parameters for VPS 107
but even after a reboot, there is no second device in the VM.
# ifup eth0
Ignoring unknown interface eth0=eth0.

also, echo 1 > /proc/sys/net/ipv4/conf/veth107.0/forwarding shows "File or Directory not found"

what now?

Could you please show "ip a l" output on the host node and inside your VE.
