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 (cherry picked from commit 378031088fc95e576e517702f0ce2aa1fb30d8c3)
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.
