Re: [Qemu-discuss] Issue related to mounting /dev/nbd0p1

[Jakob Bohm]

Check

   cat /proc/partitions

If the partitions are not listed there, the kernel does not
recognize them, perhaps the kernel doesn't recognize that
nbd0 is a "partitionable disk", and thus does not create the
internal nbd0p1 and ndb0p2 devices.

If the partitions are listed there, you just need to create the
actual /dev/nbd0p1 and /dev/nbd0p2 file names with mknod or
figure out why your "/dev/" management software (maybe udev,
maybe something better) doesn't do that for you.
