conf: Report sensible error for invalid disk name
The error "... but the cause is unknown" appeared for XMLs similar to this: <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/dev/zero'/> <target dev='sr0'/> </disk> Notice unsupported disk type (for the driver), but also no address specified. The first part is not a problem and we should not abort immediately because of that, but the combination with the address unknown was causing an unspecified error. While fixing this, I added an error to one place where this return value was not managed properly.
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.
