We shouldn't have enabled VDUSE in the RHEL build until we make an explicit decision to support this. So the fix should be to disable it again. QE bot(pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass. Passed test on 7.2.0-7.el9
qemu-storage-daemon -V
qemu-storage-daemon version 7.2.0 (qemu-kvm-7.2.0-7.el9)
root@dell-per440-07 /tmp/qemu7-7 $ qemu-storage-daemon -h
Usage: qemu-storage-daemon [options]
QEMU storage daemon
-h, --help display this help and exit
-T, --trace [[enable=]<pattern>][,events=<file>][,file=<file>]
specify tracing options
-V, --version output version information and exit
--blockdev [driver=]<driver>[,node-name=<N>][,discard=ignore|unmap]
[,cache.direct=on|off][,cache.no-flush=on|off]
[,read-only=on|off][,auto-read-only=on|off]
[,force-share=on|off][,detect-zeroes=on|off|unmap]
[,driver specific parameters...]
configure a block backend
--chardev <options> configure a character device backend
(see the qemu(1) man page for possible options)
--daemonize daemonize the process, and have the parent exit
once startup is complete
--export [type=]nbd,id=<id>,node-name=<node-name>[,name=<export-name>]
[,writable=on|off][,bitmap=<name>]
export the specified block node over NBD
(requires --nbd-server)
--export [type=]vhost-user-blk,id=<id>,node-name=<node-name>,
addr.type=unix,addr.path=<socket-path>[,writable=on|off]
[,logical-block-size=<block-size>][,num-queues=<num-queues>]
export the specified block node as a
vhost-user-blk device over UNIX domain socket
--export [type=]vhost-user-blk,id=<id>,node-name=<node-name>,
addr.type=fd,addr.str=<fd>[,writable=on|off]
[,logical-block-size=<block-size>][,num-queues=<num-queues>]
export the specified block node as a
vhost-user-blk device over file descriptor
--monitor [chardev=]name[,mode=control][,pretty[=on|off]]
configure a QMP monitor
--nbd-server addr.type=inet,addr.host=<host>,addr.port=<port>
[,tls-creds=<id>][,tls-authz=<id>][,max-connections=<n>]
--nbd-server addr.type=unix,addr.path=<path>
[,tls-creds=<id>][,tls-authz=<id>][,max-connections=<n>]
start an NBD server for exporting block nodes
--object help list object types that can be added
--object <type>,help list properties for the given object type
--object <type>[,<property>=<value>...]
create a new object of type <type>, setting
properties in the order they are specified. Note
that the 'id' property must be set.
See the qemu(1) man page for documentation of the
objects that can be added.
--pidfile <path> write process ID to a file after startup

Description of problem: There is new export type in qsd help message: --export [type=]vduse-blk,id=<id>,node-name=<node-name> ,name=<vduse-name>[,writable=on|off] [,num-queues=<num-queues>][,queue-size=<queue-size>] [,logical-block-size=<logical-block-size>] [,serial=<serial-number>] export the specified block node as a vduse-blk device But the type need kernel support and may be used in QEMU. So far, the type is not supported in QEMU. Version-Release number of selected component (if applicable): qemu-storage-daemon version 7.1.0 (qemu-kvm-7.1.0-1.el9) How reproducible: 100% Steps to Reproduce: 1.qemu-storage-daemon -h 2. 3. Actual results: Find unsupported export type in QEMU Expected results: Hide unsupported export type Additional info:
