inspect_os() shouldn't do this, but ultimately it's heuristic. As we know what the transfer device is, we can double-check the output. --- v2v/virt-v2v.pl | 18 +++++++++++++++++- 1 files changed, 17 insertions(+), 1 deletions(-) diff --git a/v2v/virt-v2v.pl b/v2v/virt-v2v.pl index fe07ae9..6e7310...

...e've currently got a bug in libguestfs which means we can't inspect filesystems in btrfs subvolumes: https://bugzilla.redhat.com/show_bug.cgi?id=824021 This is the default configuration if you select btrfs in F17+. The issue is that it requires an api to fix it, as the return values of inspect_os, inspect_get_filesystems and inspect_get_mountpoints can't express a btrfs subvolume as they're expected to be the names of block devices. As a starter for 10, I propose the addition of parallel apis suffixed _ext which return annotated device descriptions, e.g.: block:/dev/vda2 btrfsv...

...Windows we create the following dir: /Program Files/Guestfs/Firstboot/ Where '/' is the os volume (where /Windows reside) Is it possible that Program Files is not actually located on the os volume? (i.e. C:\Windows, D:\Program Files on original vm) Does virt-v2v or even libguestfs's inspect_os() even support that? (Looking around in the code tells me that if the Windows vm has multiple volumes, or even if the os drive letter is not 'C:', virt-v2v will not work correctly) Wouldn't it be safer to create the Guestfs dir directly on root, and not use the Program Files if it migh...

By creating an empty disk and using it as the first disk of the vm (i.e. /dev/sda, /dev/sdb{1,2} contains the windows fses) we change the iteration order of the disks. This causes inspect_os() to fail since Parted returns a Unix_error if the device does not contain any partitions - fix this by handling this Unix_error.
