Add yourself to kvm group or chmod 666 /dev/kvm but post the output of this and you’ll be able to see

uname -a \
; echo 1 | sudo tee /sys/module/kvm/parameters/ignore_msrs \
; grep NAME /etc/os-release \
; df -h . \
; qemu-system-x86_64 --version \

Most conceivable errors are covered here:

https://github.com/sickcodes/Docker-OSX#troubleshooting

In your case, add yourself to the relevant groups and start libvirtd etc should be fine!

If you don’t have a screen, use one one of the headless examples below the original example :)
