Does that mean NetBSD also needs PV On HVM drivers? Dunno. Probably?
NetBSD currently does not have PV on HVM drivers. I am not sure what the current state is eg there are different network options (I know that advanced networking which is Intel 10g is in development but the driver is not working yet). I would look at the NetBSD list archives for more detail. Justin > So I’m guessing maybe xen pv rump kernels could run on EC2 HVM, but perhaps first they need NetBSD PV On HVM drivers?

My current goal is to try to get existing unikernels to boot on HVM but I suspect that won’t work because NetBSD isn’t using/doesn’t have PV On HVM drivers. > > Anyone got any thoughts on any of this?
