[Qemu-devel] [PATCH v2 2/2] pc_q35: Initialize Xen.

[Anthony PERARD]

Signed-off-by: Anthony PERARD <address@hidden>

Right now, starting an HVM with Q35 chipset those not works because
HVMLoader (the Xen pre-bios) look for the standard chipset i440FX.
Especialy the PCI/ISA bridge.

Error message from HVMLoader:
assertion '(devfn != PCI_ISA_DEVFN) || ((vendor_id == 0x8086) &&
(device_id == 0x7000))'

with PCI_ISA_DEVFN 0x08 /* dev 1, fn 0 */
