We are using pci passthrough with an SCSI Adapter card. The system is:
- O.S: Ubuntu 10.04.1 LTS
- KVM Packages:
kvm 1:84+dfsg-0ubuntu16+0.12.3+noroms+0ubuntu9.2
kvm-pxe 5.4.4-1ubuntu1
qemu-kvm 0.12.3+noroms-0ubuntu9.2
libvirt-bin 0.7.5-5ubuntu27.2
python-libvirt 0.7.5-5ubuntu27.2
libvirt0 0.7.5-5ubuntu27.2
- Kernel 2.6.32.15+drm33.5.iommu recompiled with following options :
CONFIG_DMAR=y
CONFIG_INTR_REMAP=y
- Apparmor is stopped
When we started the virtual machine we obtain the following error:
char device redirected to /dev/pts/3
device: 04:04.0: driver="pci-assign" host="04:04.0"
Failed to assign irq for "04:04.0": Operation not permitted
Perhaps you are assigning a device that shares an IRQ with another device?
Thanks in advance,
Inigo
