Re: [libvirt] [PATCH v2] 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 --- src/qemu/qemu_agent.c | 37 +++++++++++++++++++++++++++++++++++-- 1 files changed, 35 insertions(+), 2 deletions(-)
