when working with VM images of various formats, qemu-nbd always worked nicely with nbd-client to give access to qcow2 images. However, this regressed in 42.1 likely related to the changelog entry

Fri Apr 17 13:27:19 UTC 2015 - mpluskal@suse.com

- Update to 3.10 * There really is only one change since 3.9: drop of the "oldstyle" support from nbd-server and nbd-client.

workaround is downgrading to nbd-3.3 from openSUSE-13.2 repo.

qemu-nbd has nothing to do with nbd package, package nbd contains nbd server, which is not involved at all when qemu-nbd is used.

Furthermore you don't need nbd installed when working with qemu-nbd -- You are receiving this mail because: You are on the CC list for the bug.

/usr/sbin/nbd-client is part of the nbd package. Ah correct Are there other clients to use the NBD exported by qemu-nbd?

maybe I should have added earlier Yes you should have

Steps To Reproduce: qemu-nbd /path/to/some.qcow2 nbd-client localhost 10809 /dev/nbd0 mount -o loop,offset=$((2048*512)) /dev/nbd0 /mnt/ Why not do something like: # qemu-nbd -c /dev/nbd0 /var/lib/libvirt/images/sle12.qcow2

Step with nbd-client is not necessary -- You are receiving this mail because: You are on the CC list for the bug.

that would indeed cover the most important use-case just not viewing/editing images over the network.

Any chance to get qemu-nbd support the new style proto or nbd-client to support oldstyle? Otherwise, please close as WONTFIX.

Not sure about qemu-nbd, but asking about return of dropped legacy support is a bit funky -> anyway imo it is upsteam issue of qemu-nbd, so perhaps it would be better to ask there. -- You are receiving this mail because: You are on the CC list for the bug.
