Brainsalad Posted January 31, 2016 Share Posted January 31, 2016 Hardware specs: Mainboard : Intel DQ35JO socket 775 CPU : Core 2 Duo E8500 Ram : 4 GB 677 DDR2 External GPU : Radeon HD 5450 1GB Hard Drive : Toshiba DT01ACA100 1TB IOMMU and HVM enabled So I ran into a Problem when I was trying to configure a NAS-MediaCenter Combo PC. The Problem is that I can´t get the Windows 10 VM to run/start. Everytime I try to create and start a new one I get the following Error: Execution error internal error: early end of file from monitor: possible problem: 2016-01-29T12:01:40.658637Z qemu-system-x86_64: -device vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on: vfio: failed to set iommu for container: Operation not permitted 2016-01-29T12:01:40.658703Z qemu-system-x86_64: -device vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on: vfio: failed to setup container for group 1 2016-01-29T12:01:40.658715Z qemu-system-x86_64: -device vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on: vfio: failed to get group 1 2016-01-29T12:01:40.658730Z qemu-system-x86_64: -device vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on: Device initialization failed 2016-01-29T12:01:40.658744Z qemu-system-x86_64: -device vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on: Device 'vfio-pci' could not be initialized This is my XML: <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> <name>Win10</name> <uuid>8fd42ed3-96db-fbb4-dadf-29fa6cb09328</uuid> <metadata> <vmtemplate name="Custom" icon="windows.png" os="windows"/> </metadata> <memory unit='KiB'>2621440</memory> <currentMemory unit='KiB'>2621440</currentMemory> <memoryBacking> <nosharepages/> <locked/> </memoryBacking> <vcpu placement='static'>1</vcpu> <cputune> <vcpupin vcpu='0' cpuset='0'/> </cputune> <os> <type arch='x86_64' machine='pc-i440fx-2.3'>hvm</type> </os> <features> <acpi/> <apic/> <hyperv> <relaxed state='on'/> <vapic state='on'/> <spinlocks state='on' retries='8191'/> </hyperv> </features> <cpu mode='host-passthrough'> <topology sockets='1' cores='1' threads='1'/> </cpu> <clock offset='localtime'> <timer name='hypervclock' present='yes'/> <timer name='hpet' present='no'/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/qemu-system-x86_64</emulator> <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='writeback'/> <source file='/mnt/user/vdisks/Win10/vdisk1.img'/> <target dev='hdc' bus='virtio'/> <boot order='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/mnt/user/isos/Windows10.iso'/> <target dev='hda' bus='ide'/> <readonly/> <boot order='2'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/mnt/user/isos/virtio-win-0.1.102.iso'/> <target dev='hdb' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> <controller type='usb' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x2'/> </controller> <controller type='pci' index='0' model='pci-root'/> <controller type='ide' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <controller type='virtio-serial' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </controller> <interface type='bridge'> <mac address='52:54:00:ab:e0:32'/> <source bridge='br0'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target type='serial' port='0'/> </console> <channel type='unix'> <source mode='bind' path='/var/lib/libvirt/qemu/channel/target/Win10.org.qemu.guest_agent.0'/> <target type='virtio' name='org.qemu.guest_agent.0'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> <memballoon model='virtio'> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </memballoon> </devices> <qemu:commandline> <qemu:arg value='-device'/> <qemu:arg value='ioh3420,bus=pci.0,addr=1c.0,multifunction=on,port=2,chassis=1,id=root.1'/> <qemu:arg value='-device'/> <qemu:arg value='vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on'/> <qemu:arg value='-device'/> <qemu:arg value='vfio-pci,host=01:00.1,bus=root.1,addr=00.1'/> </qemu:commandline> </domain> I searched on the Internet for a solution but I can´t find one that solves the Problem for me. Would be great if you could help me. Thank you beforehand. Brian Link to comment
saarg Posted January 31, 2016 Share Posted January 31, 2016 Could you post your iommu groups from Tools --> System devices? You might need to turn on the ACS override in Settings --> VM manager. Link to comment

saarg Posted January 31, 2016 Share Posted January 31, 2016 You could try to add this to your syslinux.conf after append. vfio_iommu_type1.allow_unsafe_interrupts=1 Link to comment
Jim van der Harst Posted January 31, 2016 Share Posted January 31, 2016 Agree on Saarg. I posted a solution about a similar problem: http://lime-technology.com/forum/index.php?topic=45530.0 Link to comment
Jim van der Harst Posted January 31, 2016 Share Posted January 31, 2016 In my case it was a syslinux.cfg problem.... and fixed with what Saarg said: vfio_iommu_type1.allow_unsafe_interrupts=1 default /syslinux/menu.c32 menu title Lime Technology prompt 0 timeout 50 label unRAID OS menu default kernel /bzimage append vfio_iommu_type1.allow_unsafe_interrupts=1 initrd=/bzroot Link to comment
