RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem:
Instead of virtproxyd/libvirtd/admin, we can not use virt-admin to manage other daemons directly. But we can manage it by connecting to the daemon firstly, then executing the monitor/management cmds. Please check the following steps.
Version-Release number of selected component (if applicable):
libvirt-7.10.0-1.el9.x86_64
How reproducible:
100%
Steps to Reproduce:
1. try to use virt-admin to check the info about virtqemud
# virt-admin server-threadpool-info virtqemud
error: Server not found: No server named 'virtqemud'
2. try to connect to virtqemud, then check the info about virtqemud
# virt-admin -c virtqemud:///system server-threadpool-info virtqemud
minWorkers : 5
maxWorkers : 20
nWorkers : 5
freeWorkers : 5
prioWorkers : 5
jobQueueDepth : 0
3. change the attributes of virtqemud using the above method
# virt-admin -c virtqemud:///system server-threadpool-set virtqemud --min-workers 10
# virt-admin -c virtqemud:///system server-threadpool-info virtqemud
minWorkers : 10
maxWorkers : 20
nWorkers : 10
freeWorkers : 10
prioWorkers : 5
jobQueueDepth : 0
Actual results:
But the above info has not been added to the docs, e.g., manpages, and https://libvirt.org/manpages/virt-admin.html
Expected results:
Doc about the above info should be added

v8.0.0-135-g61ad700129
Tested with:
libvirt-daemon-8.2.0-1.fc35.x86_64
check the virt-admin manpages
# man virt-admin
-c, --connect URI
Connect to the specified URI, as if by the connect command, instead of the default connection. See NOTES
NOTES
The virt-admin supports both the monolithic libvirtd daemon and the modular daemons whichever is in use by your system. The connection URI used with -c/--connect or
the connect command is based on the name of the controlled daemon e.g.: virtqemud:///system, libvirtd:///system.
Running virt-admin requires root privileges when communicating with the system instance of a daemon (URI ending in /system) due to the communications channels used to
talk to the daemon.
connect
....
See NOTES on picking the correct URI corresponding to a libvirt daemon.
Verified this bug with:
libvirt-8.2.0-1.el9.x86_64
The testing steps are the same with Comment #2.
