    So can XEN and KVM? Please google before posting

    Agreed. (And I have seen that happening)
    But guys, can we please not make it "OpenVZ vs KVM/Xen topic" and come back to my actual issue now.
    Going to link it here.

    Avoiding the peanut gallery who think OVZ has a monopoly on overselling and cannot resist the urge to point out the myth is like trying to violate the laws of physics. It's impossible.

    To me the only inconvenient part is OpenVZ kernels still do not support ipset netfilter extension. Very convenient in real-world hosting, when dynamic filtering with least possible overhead is required.

    Apart from this and similar incompatibilities, OpenVZ is the quickest in terms of running several Linux instances and taking very little for itself.

    I would add also "avoid using VSwap unless absolutely necessary", to avoid slowdown.

    You can do ipset on the node but not inside a container. Probably won't see that till CE7 kernel.

    vSwap is just RAM that is slowed down and presented as swap. An improvement over the way it was before which caused problems with java and was a major headache for me.

    This is the biggest thing on my wish-list as well.

    Aye, OpenVZ devteam knows about this request, but no definite ETA so far.

    Doing ipset on node is of no real use to me, owner of container :)
