From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; The help output for QEMU 1.2.0 changed 'pci-assign' to 'kvm-pci-assign'. Since the new capabilities code does exact device name matching instead of substring matching, this caused the capabilities to go missing. Pushed as a build break fix Signed-off-by: Daniel P.
