By soon I mean 'when I (or someone else) gets some free time' :-)

I was actually hoping we wouldn't need to run commands via ssh, instead
be able to use the lbiguestfs APIs, but that's to be investigated.
I am currently writing test cases for TPM support. What I am doing
inside the VM are things like
- check for availability of /dev/tpm0
- checking of content of /sys/devices/pnp0/00:0?/pcrs
- mounting of securityfs to /sys/kernel/security
- checking of content of /sys/kernel/security/tpm/ascii_bios_measurements
For all that I am using ssh for logging into the FC14 image and
scripting to get to the data. The existing nwfilter tests run other
commands inside the VM as well, including 'yum' to install an additional
tool (dsniff). We'd need to have similar capabilities when switch over
to whatever libguestfs can do inside the VM following commands from the
host.
From my perspective the unfortunate part is that the installation of
the FC14 image takes such a long time. However, once it's done the VM
can be used for a long time.
