October 31, 20205 yr Hello, I've just upgraded from 6.7.2 to 6.8.3 and my VM is not able to start anymore : internal error: qemu unexpectedly closed the monitor: 2020-10-31T10:24:08.413312Z qemu-system-x86_64: -device vfio-pci,host=0000:01:00.0,id=hostdev0,bus=pci.0,addr=0x3: vfio 0000:01:00.0: group 1 is not viable Please ensure all devices within the iommu_group are bound to their vfio bus driver. I went through forum. People that is facing this same issue didn't get any feedback yet. Could you please help? Thanks tower-diagnostics-20201031-1128.zip

July 24, 20232 yr Now getting this error myself running 6.11.5 with my Win 10 VM (which was working fine until this error). Frustrated as to what might have changed. Also getting "Out Of Memory errors detected on your server" from Fix Common Problems recently. Edited July 24, 20232 yr by JLKunka
