venet doesn't work on OpenVZ

Right now I'm using bridge networking in Proxmox VE node and it's CTs. I would like to change to venet. This is what I did:

1. Removed every bridge in Proxmox VE node
2. Set up the Proxmox VE node network as normal, no bridge at all
3. Removed the bridge in one of my CTs for testing purposes
4. Add venet IP address to that CT

But... I didn't work, no comunication at all.

Best regards to all
