May 24, 20224 yr Author Yes it is HP z400 Workstation internal error: qemu unexpectedly closed the monitor: 2022-05-24T19:28:46.542299Z qemu-system-x86_64: -device vfio-pci,host=0000:0f:00.0,id=hostdev0,bus=pci.0,addr=0x3: vfio 0000:0f:00.0: failed to setup container for group 17: Failed to set iommu for container: Operation not permitted
May 25, 20224 yr Try to enable unsafe interrupts: Settings -> VM -> VFIO allow unsafe interrupts -> Yes Reboot server.
May 27, 20224 yr Author Sorry it has been a while since i was able to sit down and look at it. It no longer errors out but the gpu is not outputting anything, and i know that the gpu works.
May 27, 20224 yr if it's not outputting any error you probably changed something?If this is the case new diagnostics is needed.
