Description Yanqiu Zhang 2021-05-26 08:34:54 UTC
Reproduces on:
libvirt-client-7.3.0-1.module+el8.5.0+11004+f4810536.x86_64
qemu-kvm-6.0.0-16.module+el8.5.0+10848+2dccc46d.x86_64

Can also reproduce by : start libvirt-guests -> stop libvirtd -> stop libvirt-guests.


+++ This bug was initially created as a clone of Bug #1964855 +++

Description of problem:
'systemctl stop libvirt-guests' hangs after libvirtd timeout

Version-Release number of selected component (if applicable):
libvirt-client-7.0.0-6.el9.x86_64
qemu-kvm-6.0.0-2.el9.x86_64

How reproducible:
100%

Steps to Reproduce:
1.systemctl start libvirt-guests
it will also start libvirtd

2.wait 'libvirtd --timeout 120' to timeout

3.systemctl stop libvirt-guests 


Actual results:
Step 3 hangs, actually at 'virsh connect' inside the .sh:
# ps aux|grep 'libvirt|virsh' -E
...
root       54720  0.0  0.0  20424  8540 pts/3    S+   09:07   0:00 systemctl stop libvirt-guests
root       54722  0.0  0.0   7696  4340 ?        Ss   09:07   0:00 /usr/bin/sh /usr/libexec/libvirt-guests.sh stop
root       54728  0.0  0.0 108572 16136 ?        Sl   09:07   0:00 virsh connect
...

test_connect()
{
    local uri="$1"

    if run_virsh "$uri" connect 2>/dev/null; then
        return 0;
    else
        eval_gettext "Can't connect to \$uri. Skipping."
        return 1
    fi
}

Expected results:


Additional info:
1. Not reproduces when start libvirtd -> libvirtd timeout -> start libvirt-guests", libvirtd will be auto started.
2. Can not try "start libvirtd -> start libvirt-guests -> stop libvirtd -> stop libvirt-guests", because stopping libvirtd also stopped libvirt-guests due to Bug 1946697(fixedin:libvirt-7.0.0-13)

Comment 1 Michal Privoznik 2021-06-23 13:19:20 UTC
The original bug was switched over to systemd. While I'd love ti switch this one too there's no systemd component in RHEL-AV. Thus I think we can wait a bit until the fate of the original bug is decided.

Comment 2 John Ferlan 2021-09-09 15:53:15 UTC
Bulk update: Move RHEL-AV bugs to RHEL8 with existing RHEL9 clone.

Comment 3 Jaroslav Suchanek 2023-02-02 16:41:53 UTC
This has been addressed in RHEL-9 bug 1964855.
