My troubles continue.. The vlan interfaces are up and working, however when i try to cat /proc/net/vlan/conf, it segfaults. I'm going to try bringing the system upto date with centos 4.3 and the latest openvz utils/kernel. Hopefully this issue is fixed. Has anyone else run into this problem?

Btw, I did a quick test, and the Centos 2.6.9-22.EL stock kernels are not causing segfaults, so i think this might be a bug with the openvz kernel config/modules.
