These three patches (two were previously posted) can do simple operating system inspection in C. Example of use: /dev/VolGroup00/LogVol00 linux rhel x86_64 5 5 Red Hat Enterprise Linux Server release 5.5 (Tikanga) /dev/VolGroup00/LogVol00 /dev/vda1 /dev/VolGroup00/LogVol01 /dev/VolGroup00/LogVol00: / /dev/vda1: /boot I've tested this with all of my available guests. The only ones it *doesn't* work on were a Fedora guest with an encrypted disk, and some FreeBSD/PCBSD guests. For the encrypted guest, you have to open the device first. We could probably get the *BSD guests working with some effort. Anyway I'm quite happy with this and I intend to push it if no one objects.
