RHEV Host is Non-responsive after yum upgrade

Issue

• After yum upgrade of RHEV host, the host is marked Non-responsive because vdsmd is not running. Starting vdsmd service manually fails with following error:

# service vdsmd start
initctl: Job is already running: libvirtd
vdsm: Running mkdirs
vdsm: Running configure_coredump
vdsm: Running configure_vdsm_logs
vdsm: Running run_init_hooks
vdsm: Running gencerts

RuntimeError:

One of the modules is not configured to work with VDSM.
To configure the module use the following:
'vdsm-tool configure [module_name]'.

If all modules are not configured try to use:
'vdsm-tool configure --force'
(The force flag will stop the module's service and start it
afterwards automatically to load the new configuration.)
