OpenVZ and libvirt/KVM - I don't think Xen is going anywhere in the
long term.<br>
<br>
KVM supports the use of kernel-same-page-merging (KSM), which OpenVZ
doesn't (yet?). For some applications KSM can be a big win...<br>
<br>
We currently use/support both OpenVZ and kvm.<br>

So, if the usecase does not involve running different kernels, then openvz style partitioning of system resources would yield more performance. I am looking for more evidence supporting that :)</div>
