[Libguestfs] Problem inspecting Windows images with large registry hives

Encountered the following problem and would like to know if this is a known issue, whether there's a fix, or workaround: Using libguestfs and the python bindings to inspect VMs. Fairly successfully for the most part, but had one Windows image today that fails in the following manner. File "/usr/lib/python2.7/site-packages/guestfs.py", line 910, in inspect_os r = libguestfsmod.inspect_os (self._o) RuntimeError: size of /Windows/System32/config/SOFTWARE is unreasonably large (141819904 bytes) Reproduced it with guestfish: [root@cagedbird images]# guestfish --ro -i -a windows-2008-r2-base+updates-20120518.img libguestfs: error: size of /Windows/System32/config/SOFTWARE is unreasonably large (141819904 bytes) [root@cagedbird images]# guestfish --version guestfish 1.18.12fedora=17,release=3.fc17 Unfortunately, because of this bounds check, preliminary inspection fails. Bug, or as designed? Thanks, Todd
