Just to clarify things here, we now have the "disk-image" command that produces a Hurd bootable disk-image. The "vm-image" command is almost working, and should produce a very similar result. The "vm" command that produces a vm-image and spawns a VM isn't working yet with the Hurd. This command is for now passing directly "kernel" and "initrd" arguments to QEMU, so a few adaptations will be needed. Now the goad of hurd-in-vm-service-type is to provide a service that does almost the same thing as the "vm" command, but as a service, right? So, I don't get why would we need to run a Hurd VM inside a VM. I've been struggling a lot with running nested layers of virtualization (for system generation before the recent patches), and the result is often too slow to be really usable. Thanks, Mathieu
