[RFC/PATCH] Use kernel supplied MMU info for kvm tool

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

This is a series for kvmtool that uses a newish kernel API to get
MMU info, which is then fed to the guest.

Currently we just make a good guess based on the PVR, but that is
potentially flakey in a few ways. The most notable is that if you don't
specify hugepages we don't boot - because the guest is told we support
16M pages, but we don't really (on HV).

I've tested this with 4K/64K host page size, and with hugepages, on
both 3.4 and 3.5 based host kernels. I've also given it a quick smoke
test with PR KVM, and it seems to work.

I'm seeing a guest crash with a 4K host kernel, but I think that is
unrelated, and happens with or without this patch series.

cheers
