I can confirm that there's no limit in the NetBSD kernel, and I can't see why
there would be one in the hypervisor (it shouldn't know about the devices,
it only sees page exange and interrupts between domains). There may be
a limit in xentools, but 3 or even 5 would be awfully low (I have a xen2
domU with 25 vifs ...)
