Description of problem: See: https://www.redhat.com/archives/virt-tools-list/2011-January/msg00118.html The inspection code gets confused if two partitions contains what it thinks are Windows root filesystems. Essentially the Windows root detection test is wrong: http://git.annexia.org/?p=libguestfs.git;a=blob;f=src/inspect.c;h=ac2050c69491aee8dad3642c6a973275495ad823;hb=HEAD#l368 http://git.annexia.org/?p=libguestfs.git;a=blob;f=perl/lib/Sys/Guestfs/Lib.pm;h=393eb8adb21dd4e3d40f4394a717f0d679d1dd3b;hb=HEAD#l486 Version-Release number of selected component (if applicable): libguestfs in RHEL 6.0
This was fairly simple to reproduce. First I installed Windows 7 on a VM with two virtual disks (12 GB + 512 MB). After installation I formatted the second small disk. Then I downloaded Firefox and asked it to install on to the second drive (E:). Firefox's installer created E:\Program Files\... This broke the core inspection code: it tried to find an operating system on the second disk (because it thought the presence of "/Program Files" meant it was a Windows root). It failed to determine the %SYSTEMROOT% of this second disk. The error message was: # virt-inspector Win7x32TwoDisks libguestfs: error: cannot resolve Windows %SYSTEMROOT% virt-inspector: no operating system could be detected inside this disk image. This may be because the file is not a disk image, or is not a virtual machine image, or because the OS type is not understood by libguestfs. [...]
