I ran guestmount with debugging enabled so I could see the disk
accesses (and verify that it's really accessing the guest, not the
host).  I can confirm it is accessing the guest.

sudo guestmount -a /dev/fedora/f18x64 -i --ro /tmp/mnt -x

This was the command I used to scan the guest:

sudo OSCAP_PROBE_ROOT=/tmp/mnt OSCAP_PROBE_OS_NAME=Linux OSCAP_PROBE_OS_VERSION=3.2 OSCAP_PROBE_ARCHITECTURE=x86_64 OSCAP_PROBE_PRIMARY_HOST_NAME=f18x64 ./run ./utils/oscap xccdf eval --profile F14-Default ./dist/fedora/scap-fedora14-xccdf.xml

It all appears to be working, although several tests failed (as
expected).
