The minimal install removes extras like ClamAV and other optional packages by default. The install still requires at least 1GB of RAM to install, and based on my experience 2GB of RAM is recommended for best performance.
Keep in mind, if you intend to run all services including Web Server, Database Server, and Email you’ll typically need even more RAM and potentially a reasonable amount of CPU resources.
I personally do NOT run Virtualmin installs with less than 2GB of RAM and Webmin installs (when running DNS-only or MySQL-only) with less than 1GB of RAM.
512MB may be possible in some cases, but definitely not recommended for production.
If you’d like help installing and optimizing your install, drop me a line. I have helped countless folks in the past reduce overhead and optimize their installs to run on the slimmest possible VPS’, but again this does not neglect the above recommendations.
