Re: Running OSv on kvmtool

[Waldek Kozaczuk]

Relateely I came across something called qemu-lite 
- https://github.com/clearcontainers/qemu/tree/qemu-lite-v2.9.0 
and https://github.com/intel/qemu-lite/wiki. It looks like a lighter qemu 
with many features compiled. Now QEMU+OSv runs in around 250ms.

Still 4 times slower than hyperkit on the same machine on OSX - please see

It does not support Multiboot at all. The main problem with booting OSv is
indeed the loading part. kvmtool on x86 only supports Linux bzImage. The
MIPS port supports ELF so perhaps that could be included for x86 to to boot
OSv.

Hi, thanks for the info. 

Do you know if kvmtool supports multiboot? If so which version?

The current maintainer's repo is here:

 https://git.kernel.org/pub/scm/linux/kernel/git/will/kvmtool.git

I update this github repo from time to time:

https://github.com/kvmtool/kvmtool

The above two repo should be identical at the moment.

Running OSv on kvmtool

[Waldek Kozaczuk]

Has anybody tried it? Is it lighter and faster than QEMU?

Waldek

PS. I have been trying to find an official github repo and many things 
popup but hard to tell which one is what.
