virish and virt-manager fails to installs

[Ruben Safir]

I am desperately trying to install a specific virtual image for a simple
webserver development project, and it just will not install.  I'm
following arch instruction and trying to install with a openSUSE
installation disk onto a img file that I created under /home/ruben/vm

With debugging turned on, I get this long, yet not, for me, not
understandable message
