We have updated the template list in Virtualizor , following templates are re-launched for Virtuozzo Openvz :

Centos 8 x86_64
Debian 10 x86_64

Note : To use newer templates, you will need to delete these two OS templates from panel (only if they were downloaded before re-launch) and also their caches from /vz/template/cache/ directory from all of your servers so that when you create vps using newer templates, new cache gets build and you don't face any issues.

Regards,
Virtualizor Team
