[sheepdog-users] qemu-nbd and dd

[Valerio Pachera]

Hi all, I'm wondering if using dd on top of nbd may cause problems.
Most of all I wonder how it behaves with the non allocate space.

E.g.

dog vdi create test 1G

lsmod | grep nbd || modprobe nbd

qemu-nbd -c /dev/nbd0 sheepdog:test

dd if=/dev/nbd0 of=/tmp/nbd0.img bs=1M

Is there any known issue using qemu-nbd or may I consider nbd0 as a
"normal" block device?
