Recommended Posts

今天我在将这张网卡直通给黑群晖时提示如下错误:

internal error: qemu unexpectedly closed the monitor: 2022-02-22T05:52:25.594846Z qemu-system-x86_64: -device vfio-pci,host=0000:04:00.0,id=hostdev1,bus=pci.5,addr=0x0: vfio 0000:04:00.0: Failed to set up TRIGGER eventfd signaling for interrupt INTX-0: VFIO_DEVICE_SET_IRQS failure: Device or resource busy

具体是什么问题导致的呢
