Is tap:qcow2 something that has to be done when installing the Windows domU, or
is that configured when building the LiveCD? I'll google around for some
information, but if you've run into any pitfalls, quirks, or specific configs
that work, I'd be curious to read about them.
I can't use the USB option, as our specialized application is mostly a system
checking/validation tool, and so has to be pretty static to make sure that as
we check various systems, nothing changes on the scanning system. The systems
it does scan are all on stand-alone networks, and we want to avoid the tool
from uneccesarily modifying them (I know it won't, but I'm the techie -- the
ones requiring this don't understand it at that level).
We have other methods available if this idea doesn't pan out....it'll just mean
additional hardware and Windows installs to maintain. But if this works out,
it'll save us some headaches. VirtualBox is also out because of PUEL licensing
getting in the way. Ditto for VMWare and pretty much any other commercialized
VM solution. Free is better (even if it requires some elbow grease to put

It'd be easier to use tap:qcow (or similar) so that the main image can
be read only, while the changing part is located in disk/RAM. Problem
is last time I check tap:qcow has some problems (like the fact that it
doesn't work with PV domU or Windows+GPLPV)

Why not simply :
- buy a large enough external USB HDD (70G will do)
- install Ubuntu (or your favorite distro) on it
- install Xen (method varies, depending on distro)
- install Windows HVM domU
So instead of a bootable DVD you have a bootable USB HDD. This way you
can use domU as you usually do without having to worry about tap:qcow
If you want it to be even more generic, use Virtualbox instead of Xen.
That way you can have Windows guest even on non-VT/SVM hardware
(netbooks come to mind).
