Whonix ™ Packages for Debian Hosts and Whonix ™ Host Enhancements

When applying the packages documented in the following article:

http://www.dds6qkxpwdeubwucdiaord2xgbbeyds25rbsgr73tbfpqpt4a6vjwsyd.onion/wiki/Packages_for_Debian_Hosts

These templates are not able to boot. The error message when booting is:

qrexec-daemon startup failed: Connection to the VM failed

How can I check the verbose logging of the qrexec-daemon?

Thank you

Which log file in /var/log/xen/console/guest-VMNAME.log would be the correct one to investigate?

Thank you
