The 'res' variable was only being initialized to NULL in the if (!state) path; however, that path never used res and evenutally res is assigned one of two results based on a pair of if then else if conditions. If for some reason neither of those paths was taken and the (!state) path wasn't taken, then 'res' would be indeterminate. Found by Coverity, probably a false positive based on code paths, but better safe than sorry for the future. Signed-off-by: John Ferlan <jferlan@redhat.com>
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.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
