[SOLVED] Issue with GPU passthrough Failed to mmap 0000:9e:00.0 BAR 1

[AxelTwin]

Hi there,

I get the following message while starting VM with PCIe passthrough:

vm: -device vfio-pci,host=0000:9e:00.0,id=hostpci0.0,bus=pci.0,addr=0x10.0,multifunction=on: Failed to mmap 0000:9e:00.0 BAR 1. Performance may be slow

host log says: vfio-pci 0000:9e:00.0: BAR 1: can't reserve [mem 0xb0000000-0xbffffff 64bit pref]

Can't find something that works on internet

I tried to append: video=vesafb:off video=efifb:off but no luck.

Anyone resolved similar issue ?
