The patch below fixes capabilities xml generation for
the qemu driver if the emulators aren't found in the
hardcoded paths. Current behavior will add a <guest>
entry for the emulator even if it does not exist, patch
fixes this to check that we actually have access.
This brings up another issue, that hardcoded paths
aren't exactly distro friendly. I'm not really familiar
with what options we have to allow specifying these
at build time (or something else). Anyone have an
idea?
Thanks,
Cole
