Hello Alex, You can probably say, what this message on host side means: kernel: [ 3902.124109] vfio_dma_do_map: RLIMIT_MEMLOCK (65536) exceeded The WLAN card in the VM doesn't work any more. It came up after a few times of restarting the VM (with unbinding / rebinding - procedures). I'll see if it is reproducible. I had to reboot to get it working again.
