I tested some more kernels from the ppa mentioned on the page referred to by comment #12
The last one to work for me is a 2.6.35 maverick kernel. Problems start from 2.6.36 onward, i guess that's where the pvops block driver has been included. (i tested latest versions of 2.6.36, 2.6.37, 2.6.38 and 2.6.39 available in the ppa) My guess is that pci passthrough with pvops never really worked at all in mainline kernels (for some of my hw that is). 2.6.37 shows something new: [ 1.490097] ACPI: bus type pci registered [ 1.492766] PCI: Using configuration type 1 for base access [ 1.496987] bio: create slab <bio-0> at 0 [ 1.506986] ACPI: Interpreter enabled [ 1.510008] ACPI: (supports S0 S3 S4 S5) [ 1.514761] ACPI: Using IOAPIC for interrupt routing [ 1.540064] ACPI Exception: AE_NOT_FOUND, Evaluating _PRW (20101013/scan-723) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/860175 Title: pci passthrough of snd_hda_intel or via usb to oneiric hvm breaks xen pvops drivers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/860175/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
