Why am I not able to edit any files on a windows guest using virt-edit?

Issue

• virt-edit fails to edit any files on a Windows guest OS by reporting the following error message then.

  (While trying to edit c:\boot.ini)

# virt-edit winxp /boot.ini
Using CPU model "cpu64-rhel6"
virt-edit: 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.

If you feel this is an error, please file a bug report including as much
information about the disk image as possible.

• Above message says that virt-edit can't detect an operating system inside the image of the guest specified. However this problem does not happen if the specified guest is Linux based like RHEL.
