qemu: check backing chains even when cgroup is omitted
added backing file checks just before the code that removes optional
disks if they are not present. However, the backing chain code fails in
case the disk file does not exist, which makes qemuProcessStart fail
regardless on configured startupPolicy.
Note that startupPolicy implementation is still wrong after this patch
since it only check the first file in a possible chain. It should rather
check the complete backing chain. But this is an existing limitation
that can be solved later. After all, startupPolicy is most useful for
CDROM images and they won't make use of backing files in most cases.
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.
