Is it something surprising you ?

Alex, Diana, I think even with the built-in paravirt net and block
drivers there is still a problem which I think I saw on oneiric and
right now confirmed on natty. I think it may still be unresolved even
upstream, but it was one issue I did not follow before oneiric release
as there where other pieces not working.

Booting without any xen_emul_unplug option. With the built-in blkfront
and netfront (and pci platform). All emulated devices get unplugged as
expected. The xvd driver does take over and a disk is found. It looks
like the netfront would take over as well but it is not set up. This
only works if in the config, the vif is not using type=ioemu.

Can you see the same? If yes, I need to verify this with precise guest
and host combinations and then this should get a new bug and be tracked
there. Having the options changed for natty and oneiric should be
independent. At least things get better.

Title:
  CONFIG_XEN_PLATFORM_PCI should be "y" when building  3.1 kernel

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Oneiric:
  Triaged
Status in “linux” source package in Precise:
  Fix Released

Bug description:
  It allows to load PVHVM domain having xen_platform_pci=1 in python hvm-profile.
  Also xen-blkfront and xen-netfront drivers are not included into inird.img on ISO disk,
  what requires (at first boot) :-
  (initramfs) modprobe xen-blkfront
  (initramfs) modprobe xen-netfront
  (initramfs) exit
  to continue loading PV-on-HVM domain.
