Finally, I''ve version 2 of my patches for PVH for xen (Linux patches
have been previously submitted). This is Phase I. These patches are built
on top of git c/s: 65c9792df60051b5f5eaadbc47a118cfba7edd49
Phase I:
- Establish a baseline of something working. These patches allow for
dom0 to be booted in PVH mode, and after that guests to be started
in PV, PVH, and HVM modes. I also tested booting dom0 in PV mode,
and starting PV, PVH, and HVM guests.
There are few fixme''s that I thought we could punt to Phase II.
Also, the disk must be specified as phy: in vm.cfg file:
> losetup /dev/loop1 guest.img
> vm.cfg file: disk = [''phy:/dev/loop1,xvda,w'']
I''ve not tested anything else.
Phase II:
- AMD port.
- Linux MSI-x fixup, see xen-devel thread "[PVH]: Help: msi.c".
- fine tune shutdown path. I need to look at shutdown path during
dom0 reboot and go thru the cleanup code again upon shutdown.
- arch_get_info_guest() and few other fixmes.
- Change xl to support other modes other than "phy:".
Phase III:
- VTSC support for PVH.
- Migration, shadow code. I''ve skipped shadow code for now.
Thanks for all the help,
Mukesh
