Hi Eric!
There is a small problem with our qemu-nbd cmdline interface: people
forget to use option -x or don't know about it and face into problems
with old protocol version. One of may colleagues after such situation
(because of this option, he could not use utility nbd-client, which
doesn't support old version) asked me to add comments about version
selection by -x option into --help of qemu-nbd. And really, it's not an
obvious interface solution...
Now I think, should not we use new version by default? Or, even drop old
version support at all? Anybody uses it?
from nbd spec:
... the old style negotiation is now no longer developed; starting
with version 3.10 of the reference implementation, it is also no longer
supported.
it's unsupported, I think it's ok to drop it. I can create patches, if
you agree.
