Re: [Qemu-devel] Fwd: [Qemu-discuss] pci-assign error
Dear Alex, Thank you for your answer. Unfortunately, I had not yet the opportunity to test it as I don't have a Kepler arch (I suppose it depends on it ?). I will keep you informed of the results.

Hi, A) Graphics assignment isn't supported and this likely won't be the only problem you find, but if you want to experiment with VFIO-based VGA support please try: kernel: git://github.com/awilliam/linux-vfio.git (branch next) qemu: git://github.com/awilliam/qemu-vfio.git (tag vfio-pci-for-qemu-20130401.0) I sent a qemu pull request for the latter and the kernel updates should be in 3.10. B) Does assignment of anything work on your system or do you perhaps see an error in dmesg like: No interrupt remapping support, disallowing device assignment. Re-enble with allow_unsafe_assigned_interrupts=1 module option. If so, try that. Thanks, Alex When I start the guest with libvirt, I have the following error in /var/log/libvirt/qemu/sofa.log: LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin HOME=/root USER=root LOGNAME=root QEMU_AUDIO_DRV=spice /usr/bin/kvm -name sofa -S -M pc-1.1 -m 1500 -smp 2,sockets=2,cores=1,threads=1 -uuid 1234beef -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/sofa.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x5 -drive file=/dev/vgsurcouf/sofa,if=none,id=drive-virtio-disk0,format=raw -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x6,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -drive file=/var/lib/libvirt/images/iso/debian-testing-amd64-netinst.iso,if=none,id=drive-ide0-1-0,readonly=on,format=raw -device ide-cd,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=23,id=hostnet0,vhost=on,vhostfd=24 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=...,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -chardev spicevmc,id=charchannel0,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.spice.0 -device usb-tablet,id=input0 -spice port=5900,addr=127.0.0.1,disable-ticketing,seamless-migration=on -vga qxl -global qxl-vga.ram_size=67108864 -global qxl-vga.vram_size=67108864 -device intel-hda,id=sound0,bus=pci.0,addr=0x4 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -device pci-assign,host=02:00.0,id=hostdev0,configfd=25,bus=pci.0,multifunction=on,addr=0x8 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x7 W: kvm binary is deprecated, please use qemu-system-x86_64 instead char device redirected to /dev/pts/2 (label charserial0) qemu-system-x86_64: -device pci-assign,host=02:00.0,id=hostdev0,configfd=25,bus=pci.0,multifunction=on,addr=0x8: Failed to assign device hostdev0 : Operation not permitted qemu-system-x86_64: -device pci-assign,host=02:00.0,id=hostdev0,configfd=25,bus=pci.0,multifunction=on,addr=0x8: Device 'kvm-pci-assign' could not be initialized 2013-04-03 09:44:35.398+: shutting down My host setup: Debian Wheezy + qemu 1.4.0, libvirt 1.0.4, kernel 3.8.5 My host gfx: $ lspci|grep VGA 02:00.0 VGA compatible controller: NVIDIA Corporation GT218 [Quadro NVS 300] (rev a2) I run the following to enable handle device with PCI stub, includind second function: echo 10de 10d8 /sys/bus/pci/drivers/pci-stub/new_id echo 10de 0be3 /sys/bus/pci/drivers/pci-stub/new_id echo :02:00.0 /sys/bus/pci/devices/:02:00.0/driver/unbind echo :02:00.1 /sys/bus/pci/devices/:02:00.1/driver/unbind sleep 3 echo :02:00.0 /sys/bus/pci/drivers/pci-stub/bind echo :02:00.1 /sys/bus/pci/drivers/pci-stub/bind Intel VT-d is enabled: $ dmesg |grep Directed [1.167179] PCI-DMA: Intel(R) Virtualization Technology for Directed I/O $ dmesg |grep IOMMU [0.00] Intel-IOMMU: enabled [0.171520] dmar: IOMMU 0: reg_base_addr ebffe000 ver 1:0 cap c90780106f0462 ecap f020f6 [0.171529] dmar: IOMMU 1: reg_base_addr fedc ver 1:0 cap c90780106f0462 ecap f020f6 [1.166855] IOMMU 0 0xebffe000: using Queued invalidation [1.166861] IOMMU 1 0xfedc: using Queued invalidation [1.166889] IOMMU: hardware identity mapping for device :00:00.0 [1.166891] IOMMU: hardware identity mapping for device :00:03.0 [1.166893] IOMMU: hardware identity mapping for device :00:07.0 [1.166895]
