Nevermind that running virtfs as a rootfs is a really dumb idea. You do now want to run a VM that has a rootfs that gets changed all the time behind your back.
Running qemu -snapshot on the actual root block device is the only safe way to reuse the host installation, although it gets a bit complicated if people have multiple devices mounted into the namespace.
