I'm new to OpenVZ, but have read a bit about it. My HN is running a fresh copy of Ubuntu 8.04. I followed the Debian install guide (where applicable) to configure a VE with the Ubuntu 8.04 template found on the wiki.
The VE is on it's own public IP (same subnet as the HN). The VE can ping IP addresses out on the internet and can correctly resolve domain names, but it can't ping domain names (get Destination Host Unreachable) and thus can't use apt-get to update, wget, etc.
The VE can be pinged by the HN and from inside the network by IP but not from outside the network (packets get to HN then time out). No firewall setup. Maybe I'm missing something, but I've read through all the documentation I could find, tried different variations of settings, destroyed and re-created the VE multiple times, and I'm just out of ideas. The same network does have 3 other HNs running Virtuozzo with VEs on their own public IPs working just fine. Thanks in advance for any help or suggestions!
