glib2-2.56.4-158.el8.x86_64

1. change the value of LimitNOFILE in /usr/lib/systemd/system/libvirtd.service
# cat /usr/lib/systemd/system/libvirtd.service

2. reload the daemon
# systemctl stop libvirtd
# systemctl daemon-reload
# systemctl start libvirtd

3. prepare a guest xml

4. creating and destroy the guest repeatedly
for i in {1..1000}; do echo $i; virsh create avocado-vt-vm1.xml; virsh destroy avocado-vt-vm1; done
1

Since there's technically no RHEL-AV 8.6.0 (it's content is exactly the same
as RHEL 8.6.0), I'm closing this BZ as a duplicate of the RHEL bug 2045879.
This bug was only needed for requesting RHEL-AV 8.5.0.z clone and there's no
use for this BZ now.

Please direct any questions either to the mentioned RHEL 8.6.0 bug or to the
RHEL-AV 8.5.0.z bug 2063286.
