错误如下： GUEST HOOK: 101 pre-start 101 is starting, doing preparations. kvm: -device vfio-pci,sysfsdev=/sys/bus/mdev/devices/604e42e4-2e90-11ec-8861-037c58d42915,addr=02.0,x-igd-opregion=on,driver=vfio-pci-nohotplug: vfio 604e42e4-2e90-11ec-8861-037c58d42915: error getting device from group 11: File exists Verify all devices in group 11 are bound to vfio-<bus> or pci-stub and not already in use TASK ERROR: start failed: QEMU exited with code 1 我是按照github上一个大佬的配置搞的，不同的是我用的是虚拟USB引导。我把大佬的命令和我定义USB引导的命令合并成了一句，不知哪里出了问题，出现了上面的报错。 这是合并后的配置文件： args: -device vfio-pci,sysfsdev=/sys/bus/mdev/devices/604e42e4-2e90-11ec-8861-037c58d42915,addr=02.0,x-igd-opregion=on,driver=vfio-pci-nohotplug -device 'qemu-xhci,addr=0x18' -drive 'id=synoboot,file=/root/synology/DS9180727.img,if=none,format=raw' -device 'usb-storage,id=synoboot,drive=synoboot,bootindex=5' balloon: 2048 boot: order=ide2;net0 cores: 2 cpu: host hookscript: local:snippets/101-autocreate.pl hostpci0: 0000:01:00.0 hostpci1: 0000:00:02.0,mdev=i915-GVTg_V5_8 ide2: none,media=cdrom machine: q35 memory: 4096 name: DSM7.1 net0: e1000e=E6:02:85:E1:A8:57,bridge=vmbr0,firewall=1 numa: 0 onboot: 1 ostype: l26 sata0: sdb-hhd:101/vm-101-disk-1.qcow2,size=100G,ssd=1 scsihw: virtio-scsi-pci smbios1: uuid=c31154f6-793a-4d4a-884a-7fe7cd29467d sockets: 1 usb1: host=152d:1567,usb3=1 usb2: host=1-6,usb3=1 vga: none vmgenid: 91f2a2ff-91d9-42c1-b83e-41078c9eb516 大佬要加的东西： args: -device vfio-pci,sysfsdev=/sys/bus/mdev/devices/604e42e4-2e90-11ec-8861-037c58d42915,addr=02.0,x-igd-opregion=on,driver=vfio-pci-nohotplug 单纯的虚拟USB引导：args: -device 'qemu-xhci,addr=0x18' -drive 'id=synoboot,file=/root/synology/DS9180727.img,if=none,format=raw' -device 'usb-storage,id=synoboot,drive=synoboot,bootindex=5'
太乱了 我配置文件再发一次： args: -device vfio-pci,sysfsdev=/sys/bus/mdev/devices/604e42e4-2e90-11ec-8861-037c58d42915,addr=02.0,x-igd-opregion=on,driver=vfio-pci-nohotplug -device 'qemu-xhci,addr=0x18' -drive 'id=synoboot,file=/root/synology/DS9180727.img,if=none,format=raw' -device 'usb-storage,id=synoboot,drive=synoboot,bootindex=5' balloon: 2048 boot: order=ide2;net0 cores: 2 cpu: host hookscript: local:snippets/101-autocreate.pl hostpci0: 0000:01:00.0 hostpci1: 0000:00:02.0,mdev=i915-GVTg_V5_8 ide2: none,media=cdrom machine: q35 memory: 4096 name: DSM7.1 net0: e1000e=E6:02:85:E1:A8:57,bridge=vmbr0,firewall=1 numa: 0 onboot: 1 ostype: l26 sata0: sdb-hhd:101/vm-101-disk-1.qcow2,size=100G,ssd=1 scsihw: virtio-scsi-pci smbios1: uuid=c31154f6-793a-4d4a-884a-7fe7cd29467d sockets: 1 usb1: host=152d:1567,usb3=1 usb2: host=1-6,usb3=1 vga: none vmgenid: 91f2a2ff-91d9-42c1-b83e-41078c9eb516
