Since [libvirt 8](https://github.com/libvirt/libvirt/commit/27c1d06b5bd68bdce55efff0a50a15a30cb2a96b), a warning appears when providing a ticket with a
password with length over than 8. Until now the extra characters were
dropped silently in QEMU. But with libvirt new handling of longer
passwords it causes the console trigger to fail. Now the password we
will provided will be in the right length.

OK for info. It looks like libvirt 8 was accidentally included in the oVirt Node ISO 4.4.10 3rd March.
Therefore use the February one libvirt 7.10 or if you're using upstream then the following command will work for you:
dnf install libvirt-7.10.0
