libguestfs-test-tool just tests the library.

In the library (src/launch-libvirt.c) we use a hack to detect if
kvm is supported:

  /* Big hack, instead of actually parsing the capabilities XML (XXX). */
  type = strstr (capabilities_xml, "'kvm'") != NULL ? "kvm" : "qemu";

and 'type' is directly used in the <domain type=...> field in the XML.

FWIW I see that the substring "'kvm'" does not appear in the
capabilities XML you pasted.

Rich.
