Veth interface not coming up in VPS [message #30466]

Hi,

We have setup a VPS which is running SLES 10(patched for this purpose). Due to our network setup, we are using veth network devices.

However, we have some trouble getting the network working.
We have three network interfaces (each going to separate VLANs).
One of them (the one connected to the Internet) does not come up at VPS boot properly.

Running vzctl exec VEID ifup eth2
(eth2 would be the interface) gets the interface running,
while complaining a lot, however.

A lot of errors are printed on the stderr. Here is the output:
cat: /sys/class/net/eth2/type: No such file or directory
eth2

We have all the modules which are virtualized loaded in /etc/sysconfig/vz on the host side except for IPv6. ( We are not using IPv6 ). Would this possibly be the reason for the interface not coming up on VPS start?
