The most likely candidate platform would seem to be Google Cloud:
it's KVM based and last I heard Google was offering "dedicated" network
interfaces a.k.a. ixv.

Unfortunately to run on Google Cloud we would need a working vioscsi
driver.  I have a roughly half-complete port of the OpenBSD version
on my laptop but I've never found the time to finish it.

Is it possible to use the virtual functions as multiple network
adapters under a single NetBSD kernel for testing?
