Richard Jones <rjo...@redhat.com> reported that BDRV_O_SNAPSHOT does not work
with NBD:
/usr/bin/qemu-system-x86_64 \
[...]
-device virtio-scsi-pci,id=scsi \
-drive file=nbd:localhost:61930,snapshot=on,format=raw,id=hd0,if=none \
-device scsi-hd,drive=hd0 \
[...]
gives the error:
qemu-system-x86_64: -drive
file=nbd:localhost:61930,snapshot=on,format=raw,id=hd0,if=none: could not open
disk image nbd:localhost:61930: No such file or directory
This series fixes the issue and adds a regression test, qemu-iotests 052. Run
the test like this:
$ QEMU_PROG=... PATH=... ./check -nbd 052
If Patch 1 is not applied, the test case fails. Note that the test case is
also useful with -raw or other formats.
