Re: [Xen-devel] [PATCH] Change PCI IRQ assignments

Currently, the ACPI tables provided for an HVM Xen guest do not include
tables for PCI devices. This causes the guest OS to default to IRQ 9 for all PCI devices. The PCI code assigns half the PCI IRQs to 9 and the other
half to 11, creating the possibility of confusing certain unamed OS's.
This patch avoids this issue by having the PCI code assign all PCI
interrupts to IRQ 9, matching the IRQ assignments from the ACPI tables.

How does QEMU deal with this possible confusion? Does it use different BIOS tables?
