Hi all, I have a problem with pci passthrough in xen 3.4.0 (Debian Lenny). I need to pass the audio board (which is 00:1b.0) to the domU, so I do the following: - Put pciback.permissive pciback.hide=(00:1b.0) in dom0 kernel boot options - Put swiotlb=force in domU kernel boot options - Put pci = [ ''00:1b.0'' ] in domU config file - reboot the machine I can see in dmesg the following: [ 1.170649] pciback 0000:00:1b.0: seizing device And further: [ 1.276490] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 17 (level, low) -> IRQ 17 [ 1.276518] ACPI: PCI interrupt for device 0000:00:1b.0 disabled when boot finished I did: root@debian:~# xm pci-list-assignable-devices root@debian:~# nothing appear! If I try to boot the domU I get: Error: (1, ''Operation not permitted'') What am I doing wrong? Is it a bug of pciback or something else.
