NAME

6       ImVirt - detects several virtualizations
7

SYNOPSIS

9           use ImVirt;
10           print imv_get(IMV_PROB_DEFAULT, imv_detect()),"\n";
11

DESCRIPTION

13       The "ImVirt" package tries to detect if it is run in a virtualization
14       container. At least the following container should be detected:
15
16       ARAnyM
17       KVM
18       lguest
19       LXC
20       OpenVZ
21       QEMU
22       UML
23       VirtualBox
24       Virtual PC/Server
25       VMware
26       Xen
27

DETECTION HEURISTIC

29       The detection is based on a heuristic - you should not trust the result
30       at all.
31
32       ImVirt probes for different well-known characteristics of different
33       virtualization containers. Any characteristics found or not found are
34       weighted by their significance.
35
36       The result of the heuristic is a weighted tree. The leaves are the
37       (not) detected containers.
38

FUNCTIONS

40       The following functions should be used to retrieve the detected
41       virtualization containers:
42
43       imv_get($prob) Returns exactly one string describing the detected
44       container. If the detected container has a smaller match probability
45       than $prob the string 'Unknown' is returned.
46       imv_get_all() Returns a hash any positive detected containers as keys
47       and their corresponding match probability as value.
48       imv_get_pos_results() Returns a list of all possible results which
49       might be returned by all detection modules. The list entries might be
50       appended by some additional data like version numbers etc.
