[Openstack] Unable to start devstack@n-cpu.service


thanks for the response, as suggested I have tried stable/queens but 
still getting the same error.
Few observations

 1. services rngd.service  and devstack at n-cpu.service are failed to start.
 2. processor family - AMD Phenom(tm) II X4 955 Processor
 3. openvswitch.service is in exited state


please find attached

 1. output of*journalctl-n-cpu*
 2. output of systemctl list-units
 3. /etc/nova/nova.conf
 4. /proc/cpuinfo

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

192 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
