tag/ virtualization

A while back, I posted about detecting virtualization on Linux from a shell, using various tricks. Around that time, I also implemented those tricks as a perl script for internal use at work with the intent of eventually cleaning it up for public consumption. I finally got around to doing it, and the result is Sys::Detect::Virtualization availabe from CPAN, or from GitHub.

Currently, it can only handle Linux, and is only tested on a small number of virtualization hosts. Patches are welcome.

Update: You may be interested in the perl module implementing these tricks.

Frequently, our customers want to install our software in a virtual machine. This can be OK, but frequently they hit a CPU, memory, or IO limit caused by running in a constrained virtual environment. When this happens, we really like to know if they're running under virtualization when we try to support them. Here's some tricks to detect, from a shell, if the system is virtualized.
