mt3 Posted August 13, 2021 Share Posted August 13, 2021 So I set up a Windows VM with GPU passthrough today and everything worked fine and I was even playing a game. The I shut down the VM and I few hours loaded it up again and now the GPU won't pass through. I made no other changes. When I connect with RDP the device manager does not show my GPU, if I connect with splashtop or parsec I just get a black screen CPU - i5-10600k - I do use intel quick sync for hardware transcoding in plex GPU - NVIDIA GTX 980 my VM log when it boots up -nodefaults \ -chardev socket,id=charmonitor,fd=32,server,nowait \ -mon chardev=charmonitor,id=monitor,mode=control \ -rtc base=localtime \ -no-hpet \ -no-shutdown \ -boot strict=on \ -device pcie-root-port,port=0x8,chassis=1,id=pci.1,bus=pcie.0,multifunction=on,addr=0x1 \ -device pcie-root-port,port=0x9,chassis=2,id=pci.2,bus=pcie.0,addr=0x1.0x1 \ -device pcie-root-port,port=0xa,chassis=3,id=pci.3,bus=pcie.0,addr=0x1.0x2 \ -device pcie-root-port,port=0x13,chassis=4,id=pci.4,bus=pcie.0,addr=0x2.0x3 \ -device pcie-root-port,port=0x14,chassis=5,id=pci.5,bus=pcie.0,addr=0x2.0x4 \ -device ich9-usb-ehci1,id=usb,bus=pcie.0,addr=0x7.0x7 \ -device ich9-usb-uhci1,masterbus=usb.0,firstport=0,bus=pcie.0,multifunction=on,addr=0x7 \ -device ich9-usb-uhci2,masterbus=usb.0,firstport=2,bus=pcie.0,addr=0x7.0x1 \ -device ich9-usb-uhci3,masterbus=usb.0,firstport=4,bus=pcie.0,addr=0x7.0x2 \ -device virtio-serial-pci,id=virtio-serial0,bus=pci.2,addr=0x0 \ -blockdev '{"driver":"file","filename":"/mnt/user/domains/Windows 10 - GPU/vdisk1.img","node-name":"libvirt-3-storage","cache":{"direct":false,"no-flush":false},"auto-read-only":true,"discard":"unmap"}' \ -blockdev '{"node-name":"libvirt-3-format","read-only":false,"cache":{"direct":false,"no-flush":false},"driver":"raw","file":"libvirt-3-storage"}' \ -device virtio-blk-pci,bus=pci.3,addr=0x0,drive=libvirt-3-format,id=virtio-disk2,bootindex=1,write-cache=on \ -blockdev '{"driver":"file","filename":"/mnt/user/isos/Windows.iso","node-name":"libvirt-2-storage","auto-read-only":true,"discard":"unmap"}' \ -blockdev '{"node-name":"libvirt-2-format","read-only":true,"driver":"raw","file":"libvirt-2-storage"}' \ -device ide-cd,bus=ide.0,drive=libvirt-2-format,id=sata0-0-0,bootindex=2 \ -blockdev '{"driver":"file","filename":"/mnt/user/isos/virtio-win-0.1.190-1.iso","node-name":"libvirt-1-storage","auto-read-only":true,"discard":"unmap"}' \ -blockdev '{"node-name":"libvirt-1-format","read-only":true,"driver":"raw","file":"libvirt-1-storage"}' \ -device ide-cd,bus=ide.1,drive=libvirt-1-format,id=sata0-0-1 \ -netdev tap,fd=34,id=hostnet0 \ -device virtio-net,netdev=hostnet0,id=net0,mac=52:54:00:d5:54:84,bus=pci.1,addr=0x0 \ -chardev pty,id=charserial0 \ -device isa-serial,chardev=charserial0,id=serial0 \ -chardev socket,id=charchannel0,fd=35,server,nowait \ -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=org.qemu.guest_agent.0 \ -device usb-tablet,id=input0,bus=usb.0,port=1 \ -device vfio-pci,host=0000:01:00.0,id=hostdev0,bus=pci.4,addr=0x0,romfile=/mnt/user/isos/vbios/EVGAGTX9801.rom \ -device vfio-pci,host=0000:01:00.1,id=hostdev1,bus=pci.5,addr=0x0 \ -sandbox on,obsolete=deny,elevateprivileges=deny,spawn=deny,resourcecontrol=deny \ -msg timestamp=on 2021-08-13 17:30:50.796+0000: Domain id=2 is tainted: high-privileges 2021-08-13 17:30:50.796+0000: Domain id=2 is tainted: host-cpu char device redirected to /dev/pts/0 (label charserial0) Link to comment
