I'm not sure about xhyve, but I vaguely remember Hyper-V supports nested virtualization but only on Windows guests. Something Microsoft seems to need that for the upcoming Windows containers. Your best option for nested virtualization seems to be qemu, but you don't need virtualization for Docker on Linux so it's pointless. VirtualBox doesn't support nested virtualization either.
