Before this patch, the translation function still needs a second ugly helper function to actually format the command line for qemu. But if we do the right stuff in the translation function, we don't have to bother with the second function any more. This patch removes the messy qemuBuildVolumeString function and changes qemuTranslateDiskSourcePool to set stuff up correctly so that the regular code paths meant for volumes can be used to format the command line correctly. For this purpose a new helper "qemuDiskGetActualType()" is introduced to return the type of the volume in a pool. As a part of the refactor the qemuTranslateDiskSourcePool function is fixed to do decisions based on the pool type instead of the volume type. This allows to separate pool-type-specific stuff more clearly and will ease addition of other pool types that will require certain other operations to get the correct pool source. The previously fixed tests should make sure that we don't break stuff that was working before.
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.
