RootCmd
To access the guest disk from the host (and e.g. chroot into the guest), use a "Network Block Device":
root #
modprobe nbd max_part=16
root #
qemu-nbd -c /dev/nbd0 Gentoo-VM.img
root #
mount /dev/nbd0p4 /mnt/gentoo
Make any changes required and clean up:
root #
umount /mnt/gentoo
root #
qemu-nbd -d /dev/nbd0
Assuming that there exists a bridge called br0
on the machine, the following configuration exposes the image to the LAN.
