mrforsythexter Posted July 1, 2020 Share Posted July 1, 2020 (edited) So, I had a VM setup and GPU passthough working, all using the interface, then a couple of reboots later, it was dead in the water. I would like to avoid rebuilding the VM if possible. on the host. the device is listed here IOMMU Group 11 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP107GL [Quadro P620] [10de:1cb6] (rev a1) This is the only thing in that group (even though it does have HDMI audio in group 12. lsPCI information from the host, not guest 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP107GL [Quadro P620] [10de:1cb6] (rev a1) In my KVM configuration file I have <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> </source> <alias name='hostdev0'/> <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x0'/> </hostdev> However when starting the guest vm up, and running LSPCI, I am not seeing the device, which was once there? Is anyone able to help, point me in the right direction (video / post).. Do you need to see anthing else from the configuration or guest? Thank you Edited July 2, 2020 by mrforsythexter Quote Link to comment
