Oh yeah, I'd forgotten those details:  with OpenVZ (and probably LXC?) you
can't configure iptables, as you're sharing a kernel.  You also can't use
tun/tap interfaces, for the reasons Michael mentioned -- which means you
can't run an OpenVPN server, for example.

I've been using Xen or KVM VMs for so long that I forgot how much I dislike
OpenVZ.  OpenVZ probably works well enough for some use cases for users who
have control of the host (i.e., not VPSs.)
