qemu: Need to check for machine.os when using ADDRESS_TYPE_CCW
https://bugzilla.redhat.com/show_bug.cgi?id=1258361 When attaching a disk, controller, or rng using an address type ccw or s390, we need to ensure the support is provided by both the machine.os and the emulator capabilities (corollary to unconditional setting when address was not provided for the correct machine.os and emulator. For an inactive guest, an addition followed by a start would cause the startup to fail after qemu_command builds the command line and attempts to start the guest. For an active guest, libvirtd would crash.
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
