Dear Maintainer,

   * What led up to the situation?
I wanted to use virt-manager to install a debian s390x guest on an amd64 host
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
I used virt-manager in the ordinary way, and selected the s390x architecture
   * What was the outcome of this action?
virt-manager got as far as attempting to boot the guest but then indicated that
the guest was not running.
   * What outcome did you expect instead?
A dialogue with the debian installer resulting in a viable s390x installation.
