Cause:
Windows guest has an HP recovery partition.
Consequence:
libguestfs confuses the HP recovery partition with an ordinary Windows partition, so thinks the guest is dual-boot. Various virt tools including virt-v2v and virt-p2v refuse to deal with multi-boot guests, so they wouldn't work.
Fix:
libguestfs now recognizes the special HP recovery partition.
Result:
libguestfs, virt tools, virt-v2v, and virt-p2v can now be used on these guests.

The root cause appears to be because the system has an HP_recovery partition (as drive D:) This contains files with names like autoexec.bat and boot.ini which confuses our windows root detection. Fixed upstream: http://git.annexia.org/?p=libguestfs.git;a=commitdiff;h=2c57305f72cd6181d1849ae6e1b892aa01c7f844

Reproduced accord to comment 12 on libguestfs-1.7.17-26, verified on libguestfs-1.16.19-1. Steps: 1. Make sure libguestfs-winsupport is installed. 2. Take any Windows guest. 3. Create a second disk (called 'test1.img') using these commands: cd /tmp guestfish -N fs:ntfs -m /dev/sda1 touch /AUTOEXEC.BAT 4. Try to inspect the guest + the second disk: guestfish --ro -i -a /home/data/images/Win2008r2-64-hvm.raw -a /tmp/test1.img Test result: On libguestfs-1.7.17-26: At step 4, following error message shows up. libguestfs: error: cannot resolve Windows %SYSTEMROOT% On libguestfs-1.16.19-1: At step4, Windows guest is found and mounted correctly as following: # guestfish --ro -i -a /home/data/images/Win2008r2-64-hvm.raw -a /tmp/test1.img Welcome to guestfish, the libguestfs filesystem interactive shell for editing virtual machine filesystems. Type: 'help' for help on commands 'man' to read the manual 'quit' to quit the shell Operating system: Windows Server 2008 R2 Standard /dev/vda1 mounted on / ><fs> According to above result, change this bug to VERIFIED.
