The most recent entry in this log file is from Wed, 27 Feb 2019 so it can't
be the log for the virt-manager you were running when the error occurred.

There are a couple possibilities for this discrepancy.

1) Are you using ssh to log into another machine and launching virt-manager
from there? In this case the version of virt-manager and log file would
be different than what is found on your local host.

2) The log file is found in a different home directory. If you are launching
virt-manager as root, it is in /root/.cache/virt-manager/virt-manager.log.
If you are launching as a user and entering the root password then the
log file is in /home/<your user name>/.cache/virt-manager/virt-manager.log
