that the 'id' property must be set.
See the qemu(1) man page for documentation of the
objects that can be added.

So there are two parts to this, it seems. The incorrectly displayed help for the FUSE export even if FUSE is disabled should already be fixed with the 6.2 rebase (commit d1bbd965bd9). Adding help for the vhost-user-blk export is the patch Philippe referenced in comment 2 and needs backporting once it is merged upstream. (In reply to Kevin Wolf from comment #4) > Adding help for the vhost-user-blk export is the patch Philippe referenced > in comment 2 and needs backporting once it is merged upstream. Merged upstream as c8cbc952426 ("qemu-storage-daemon: Add vhost-user-blk help"). Thanks for the reminder, Phil! QE bot(pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass.

Description of problem: The fuse feature is not supported, but the help message still have relevant information. If we do not support it, those message should be removed. Version-Release number of selected component (if applicable): qemu-kvm-common-6.0.0-16.module+el8.5.0+10848+2dccc46d.x86_64 How reproducible: Steps to Reproduce: 1. qemu-storage-daemon -h --export [type=]fuse,id=<id>,node-name=<node-name>,mountpoint=<file> [,growable=on|off][,writable=on|off] export the specified block node over FUSE 2. qemu-storage-daemon --blockdev driver=file,node-name=file,filename=disk.qcow2 --blockdev driver=qcow2,node-name=qcow2,file=file --export fuse,id=export,node-name=qcow2,mountpoint=disk.raw,writable=on qemu-storage-daemon: --export fuse,id=export,node-name=qcow2,mountpoint=disk.raw,writable=on: Invalid parameter 'fuse' 3. Actual results: step1 the help message introduced the fuse usage. Expected results: The help message should remove fuse relevant information if we do not support the feature. Additional info:
