Hi,
While Sub-Servers (sub-domains) are far more superior in Virtualmin over the way cPanel does Sub-Domains, it’s possible to enable the cPanel way, though keep in mind this feature may not work as well, and may be removed in a future version of Virtualmin.
First off, before you follow the below steps, please read:
http://www.virtualmin.com/documentation/system/cpanel#creating_a_sub-domain
== ENABLING CPANEL SUB-DOMAINS ==
The option is off by default, however you can accomplish the task of enabling cPanel style sub-domains by going to:
Virtualmin > System Settings > Virtualmin Configuration > Advanced Options
Look for the setting “Allow creation of sub-domains?”, and change to “Yes”.
Once again, this will enable cPanel style sub-domains, but in retrospect, just because another program chooses to do things this way, does NOT mean it’s the best or superior way of doing things. Personally, I prefer Sub-Servers as I find them more powerful, and the isolation of things is quite nice.
