Hello Dmitry,

Yeah that was my blindness on the distribution file. Saw the desc/summary have the same info and scrolled right past the distribution entry. 

I tried to do that test with adding the distribution file, but (and I am going to guess this might be due to a Solus thing) the template will fail to build due to this:

2017-11-13T18:57:42-0500 vzctl : CT 320 : running: /usr/sbin/vzpkg info -q --config ve-320.conf-sample --ostemplate gentoo-2011-x86_64-default --vefstype ext4
2017-11-13T18:57:42-0500 vzctl : CT 320 : Cached package set 'gentoo-2011-x86_64-default' is not found, run create cache utility...
2017-11-13T18:57:42-0500 vzctl : CT 320 : running: /usr/sbin/vzpkg create cache gentoo-2011-x86_64-default --vefstype ext4
2017-11-13T18:57:42-0500 vzctl : CT 320 : Creating OS template cache for gentoo-2011-x86_64-default template
2017-11-13T18:57:42-0500 vzctl : CT 320 : Looking for the precreated template cache /vz/template/cache/gentoo-2011-x86_64-default.tar.gz
2017-11-13T18:57:42-0500 vzctl : CT 320 : Error: Config directory for the selected template already exists: /vz/template/gentoo/2011/x86_64/config/os/default
2017-11-13T18:57:42-0500 vzctl : CT 320 : Error: Remove this config directory and run the script again
2017-11-13T18:57:42-0500 vzctl : CT 320 : Error: Failed to convert the precreated cache /vz/template/cache/gentoo-2011-x86_64-default.tar.gz

But if I delete the complaining directory, then so goes the distribution file that is not being generated.

Until openvz7 we never switch to ploop files, so much of this is new to me and a very frustrating change (as one can probably imagine). 

I will look at it more tomorrow when I am less distracted by another node thats causing me grief.

Thanks for the info though Dmitry, this is very likely the issue I have been having with both the slackware and gentoo templates and both did not have the distribution files in the respective cache directories.
