F2EB4Y http:OpenVZ provides [[veth]] (Virtual eTHernet) or [[venet]] (Virtual NETwork) devices (or both) for in-[[CT]] networking. Here we describe the differences between those devices. * ''veth'' allows broadcasts in CT, so you can use even a DHCP server inside a CT, or a samba server with domain broadcasts or other such stuff.* ''veth'' has some security implications. It is normally bridged directly to the host physical ethernet device and so must be treated with the same considerations as a real ethernet device on a standalone host. The CT users can access a ''veth'' device as they would a real ethernet interface. However, the CT root user is the only one that has priviledged access to the ''veth'' device.* With ''venet'' device, only OpenVZ host node administrator can assign an IP to a CT. With ''veth'' device, network settings can be fully done on CT side by the CT administrator. CT should setup correct gateway, IP/netmask etc. and then a [[HN|node]] admin can only choose where your traffic goes.* ''veth'' devices can be bridged together and/ontogenor with other devices. For example, in host system admin can bridge ''veth'' from 2 CTs with some VLAN eth0.X. In this case, these 2 CTs will be connected to this VLAN.com<* ''venet'' device is a hrefbit faster and more efficient.* With ''veth'' devices, IPv6 auto generates an address from MAC.
