Ok, I've done VMs inside docker already which has been fine, was hoping GCE would let me do it on Google's systems.

  As someone who doesn't know, why would you want to run VMs inside of a docker container? Wouldn't this have tremendous overhead relative to just running the hypervisor?

    If you use the -privileged flag, docker containers can access /dev/kvm and start low-overhead KVM instances. It's advantageous for me, because I can say "hey check out this software" and they just have to run a single docker command, compared to installing Go, apt-getting a bunch of packages, fetching our repo, compiling, etc.

      Why do you need the VM (as opposed to just containers)?
      • jff 12y ago
        Because the software I'm attempting to demonstrate/distribute is specifically designed for running VMs. That is its sole purpose--sorta like OpenStack.
