Actually, I've ran Docker within QEMU within Docker (using v9fs so that QEMU could use the container's FS as root FS). Works, but painfully slow and not very resource-efficient :-)

I will add that Docker is getting an architecture upgrade, and in the future will support nesting :)

Yeah, I was kidding about Docker in KVM in Docker. I know it would be a lot of overhead.
