Description Richard W.M. Jones 2014-09-10 12:05:59 UTC 
+++ This bug was initially created as a clone of Bug #1139659 +++

Description of problem:

Note this requires that you have fixed bug 1134592 in libvirt first.

If you create a backing file that references an ssh server,
libvirt doesn't pass the required SSH_* variables through to
qemu so it cannot access the ssh agent.

$ qemu-img create -f qcow2 \
  -b 'json: { "file.driver":"ssh",
              "file.path":"/mnt/scratch/test1.img",
              "file.user":"rjones",
              "file.host":"onuma.home.annexia.org",
              "file.host_key_check":"no" }' test2.img

$ ~/d/libvirt/run guestfish -a test2.img run
[...]
Original error from libvirt: internal error: early end of file from monitor: possible problem:
2014-09-09T11:36:32.304954Z qemu-system-x86_64: -drive file=/tmp/test2.img,if=none,id=drive-scsi0-0-0-0,format=qcow2,cache=writeback: could not open disk image /tmp/test2.img: Could not open backing file: failed to connect to ssh-agent: no auth sock variable (libssh2 error code: -39)
 [code=1 domain=10]

Dan suggests that I make this bug into a more general feature request.

These proposed commits would mean we no longer need this in libvirt:

This bug is going to be addressed in next major release.
Comment 11 Richard W.M. Jones 2020-02-10 15:40:26 UTC 
This no longer affects virt-v2v upstream, still affects RHEL AV 8.2, but
we will rebase in AV 8.3 at which point it won't affect downstream.

Still be a nice to fix for other users of course.
Comment 13 Jaroslav Suchanek 2020-11-06 12:36:20 UTC 
This bug was closed deferred as a result of bug triage.

Please reopen if you disagree and provide justification why this bug should
get enough priority. Most important would be information about impact on
customer or layered product. Please indicate requested target release.
