Playing around with runcvm, a docker runtime plugin.
One of our engineers came across this little nugget of awesomeness, RunCVM: https://github.com/newsnowlabs/runcvm and I wanted to take it for a spin.
Its simple and easy to get running, and even better, Portainer works with it flawlessly... so, if you need to spin up containers in VMs, give it a whirl.
