Well its working now and my source routing problem is fixed too. cat /proc/net/vlan/config no longer seg faults. I suspect it was fixed in either the updates to centos 4.3 (from 4.2) or to openvz kernel 2.6.8-022stab072.2 (from 70.1)
One other thing, if anyone has this problem:
Mar 28 01:47:33 storm ifup: e100 device eth0.0 does not seem to be present, delaying initialization.
Mar 28 01:47:33 storm network: Bringing up interface vlan0: failed
I had to hack /etc/sysconfig/network-scripts/ifup to fix support for vlan id 0. Maybe there is support for vid 0, but for whatever reason its not working with my config. If i do vconfig add eth0 0 then ifup eth0.0 it works fine. But i needed this dirty patch for it to work on startup. Maybe someone with better knowledge of the initscripts can check into this.
Search for,
if [ -n "$VID" ]; then
add this above it,
if [ "$DEVICE" == "eth0.0" ]; then
VID="0"
fi
