[Xen-devel] Help PIIX4 IDE interface

[sanjay T R <sanjaytr29@xxxxxxxxx>]

Hi,

Does Xen-4.4.1 or later version support PIIX4 IDE interface. Going through the Xen code it looks like it is supported but when I try booting a Linux VM it comes up with PIIX3 IDE interface. Please let me know if PIIX4 IDE is supported and can be configured in some way.

lspci on linux VM

00:01.0 ISA bridge: Intel Corporation 82371SB PIIX3 ISA [Natoma/Triton II]
00:01.1 IDE interface: Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II]
00:01.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 03)

Thanks,

Sanjay
