NAME
ImVirt - detects several virtualizations
SYNOPSIS
use ImVirt;
print imv_get(IMV_PROB_DEFAULT, imv_detect()),"
";
DESCRIPTION
The "ImVirt" package tries to detect if it is run in a virtualization container. At least the following container should be detected:
ARAnyM
KVM
lguest
LXC
OpenVZ
QEMU
UML
VirtualBox
Virtual PC/Server
VMware
Xen
DETECTION HEURISTIC
The detection is based on a heuristic - you should not trust the result at all.
ImVirt probes for different well-known characteristics of different virtualization containers. Any characteristics found or not found are
weighted by their significance.
The result of the heuristic is a weighted tree. The leaves are the (not) detected containers.
FUNCTIONS
The following functions should be used to retrieve the detected virtualization containers:
imv_get($prob) Returns exactly one string describing the detected container. If the detected container has a smaller match probability than
$prob the string 'Unknown' is returned.
imv_get_all() Returns a hash any positive detected containers as keys and their corresponding match probability as value.
imv_get_pos_results() Returns a list of all possible results which might be returned by all detection modules. The list entries might be
appended by some additional data like version numbers etc.
