I was wondering if openvz avoids context switching when delivering network packets to a VE. Seems like this is an issue with xen. Some interesting references:

Any comment from the openvz developers?

In OpenVZ delivering of network packets to VE is almost the same process, as in native Linux kernel. And yes, we avoid excessive context switches - this is one of the advantages of OS-level virtualization.
