Re: [Libguestfs] [PATCH libnbd] copy: Always allow multiple connections

Actually no, I had to revert this.


I added a test:


However the test deadlocks when we try to open multiple connections to
qemu-nbd (with your patch).  As best I can tell this is because of
qemu's file locking.  qemu-nbd doesn't seem to support the -U option
found in qemu-img, but even if it did I don't think it would be a good
idea to tell users that they have to use it.

I think this needs to be fixed in qemu-nbd itself.
