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
