System Info

OS: pop!_os 20.04
Kernel: 5.4.0-7634-generic

Steps taken

  1. Installed package pre-reqs via sudo apt install qemu qemu-kvm libvirt-clients libvirt-daemon-system bridge-utils virt-manager
  2. Ran
sudo systemctl enable libvirtd.service
sudo systemctl enable virtlogd.service
sudo modprobe kvm
  1. Ran egrep -c '(svm|vmx)' /proc/cpuinfo and got 8.
  2. Rebooted.
  3. Verified /dev/kvm had permissions 666.
  4. Ran docker pull sickcodes/docker-osx
  5. Ran docker run --privileged -v /tmp/.X11-unix:/tmp/.X11-unix sickcodes/docker-osx
