I know you just moved it from above, but isn’t this wrong? Shouldn’t it be s/backing/file/g?
Indeed; file.file.driver=file,file.file.filename=file.qcow2 is required for it to work, rather than fail with qemu-nbd: Failed to blk_new_open 'driver=raw,offset=1m,size=100m,file.driver=qcow2,file.backing.driver=file,file.backing.filename=file4': A block device must be specified for "file" I'll repost with the bug-fix as a separate commit (and it's a shame that we've gone nearly a year with no one noticing the typo in the original). -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org
