https://bugzilla.novell.com/show_bug.cgi?id=464252 Summary: xen PV pci passtrough not working, no interrupts in domU Product: openSUSE 11.0 Version: Final Platform: x86 OS/Version: openSUSE 11.0 Status: NEW Severity: Major Priority: P5 - None Component: Xen AssignedTo: cgriffin@novell.com ReportedBy: frank.mueller@rhoen.de QAContact: qa@suse.de Found By: Customer Hi, i am having problem with doing PCI-passtrough with xen to a PV domU. I tried now the default xen package in 11.0 and the default xen package in 11.1, both showing same behaviour. Passing PCI devices into a domU seems to work, device shows up in domu, but there is no interrupt for the device in domU, i use late binding with pciback to hide the pci devices from dom0. 1. Interrupts from dom0 before pcihide interupts dom0 ( 18 and 19 are the pci devices) CPU0 CPU1 1: 10 0 Phys-irq-level i8042 4: 6 0 Phys-irq-level 5: 0 0 Phys-irq-level parport0 8: 0 0 Phys-irq-level rtc0 9: 0 0 Phys-irq-level acpi 12: 131 0 Phys-irq-level i8042 14: 2513 0 Phys-irq-level ide0 18: 0 0 Phys-irq-level Technisat/B2C2 FlexCop II/IIb/III Digital TV PCI Driver 19: 44 0 Phys-irq-level saa7146 (0) 2.
