"VFIO_MAP_DMA failed: Cannot allocate memory" in docker environment

[y0va]

In docker environment host usb address range seems to be unaccessible. See also https://github.com/sickcodes/Docker-OSX/issues/133#issuecomment-894647710

With following command:

docker run -it \
           --privileged \
           --device /dev/kvm -p 50922:10022 \
           -e DEVICE_MODEL="iMacPro1,1" \
           -e WIDTH=1440 \
           -e HEIGHT=900 \
           -e RAM=16 \
           -e CORES=4 \
           -e INTERNAL_SSH_PORT=23 \
           -e AUDIO_DRIVER=none \
           -v /dev:/dev \
           -v /sys:/sys \

           -e EXTRA="-device pcie-root-port,bus=pcie.0,multifunction=on,port=1,chassis=1,id=port.1 -device vfio-pci,host="00:1a.0",bus=port.1" \

           -e MASTER_PLIST_URL=https://raw.githubusercontent.com/sickcodes/osx-serial-generator/master/config-custom.plist sickcodes/docker-osx:big-sur

I get

Did you manage to get this working? I also have the same now.

qemu-system-x86_64: -device vfio-pci,host=0000:0a:00.3,bus=port.1: VFIO_MAP_DMA failed: Cannot allocate memory
qemu-system-x86_64: -device vfio-pci,host=0000:0a:00.3,bus=port.1: vfio 0000:0a:00.3: failed to setup container for group 14:```

Hi,

Add this to /etc/security/limits.conf

*            soft    memlock         unlimited
*            hard    memlock         unlimited

And it's resolved.
