Subject: [PATCH] qemuBlockGetBackingStoreString: Add extra wrapping object to
JSON strings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
QEMU requires an extra wrapper object where only the "file" member is
populated. This is basically a placeholder for establishing the format
layer. We did the same in qemuDiskSourceGetProps for the old-school
JSON usage with -drive but forgot to adopt this for -blockdev.
