If you ran it in a Xen PV domU (or maybe an HVM domain with PV net drivers)
the network performance ought to be OK. Other than maybe generating more
traffic, it's not going to seem much different to Xen, I'd have thought?
There *is* an argument for running OpenVZ VMs in a domU only, I suppose: a
kernel exploit can - in principle - allow an OpenVZ guest to take over the
kernel and thus the whole OpenVZ machine. If your OpenVZ is in a domU this
puts a hard barrier between your OpenVZ VMs and dom0, just as you already
have between other Xen domains and dom0.
Cheers,
Mark
