qemu_agent: Report error class at least
Currently, qemu GA is not providing 'desc' field for errors like we are used to from qemu monitor. Therefore, we fall back to this general 'unknown error' string. However, GA is reporting 'class' which is not perfect, but much more helpful than generic error string. Thus we should fall back to class firstly and if even no class is presented, then we can fall back to that generic string. Before this patch: virsh # dompmsuspend --target mem f16 error: Domain f16 could not be suspended error: internal error unable to execute QEMU command 'guest-suspend-ram': unknown QEMU command error After this patch: virsh # dompmsuspend --target mem f16 error: Domain f16 could not be suspended error: internal error unable to execute QEMU command 'guest-suspend-ram': The command has not been found
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
Hypervisor.
