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

Actually no, I had to revert this. https://gitlab.com/nbdkit/libnbd/-/commit/fb42056929e9177e0de2603e2f430a8... I added a test: https://gitlab.com/nbdkit/libnbd/-/commit/23b41ad0a2a6d6582a8e643e42960d2... 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.
