FWIW: KVM is a type-2 hypervisor, Xen (and ACRN and a few others) are
type-1. Both have advantages and disadvantages.
For example, a type-2 hypervisor is very difficult to tune for running RT
OSes while ACRN (and even Xen lately -- especially on ARM) do it with no
sweat.

Thanks Pekka, I'll check it out. One of the advantages of KVM is supposed
to be that it uses the Linux kernel scheduler instead of having two
schedulers, such as Xen's scheduler + a VM's or unikernel's scheduler. I'll
see what the paper has to say about that.

Hi all -- Does OSv have its own scheduler, or does it rely on the Xen
scheduler?
I guess this might be similar to asking if OSv has threads. I have no idea.
I'm not sure what being a unikernel is supposed to imply for threads.
Thanks,
