Thanks Jian , but still instance is not spawning in Compute node , I have started the above said service but its not creating instance. In mysql i can see the below error message .
mysql -uroot -p
use nova;
select * from instance_faults;
instance_uuid: 603e82b9-9147-4208-a89d-217af0fb5a96
code: 500
message: libvirtError
details: Unable to read from monitor: Connection reset by peer
File "/usr/lib/python2.7/dist-packages/libvirt.py", line 581, in createWithFlags
if ret == -1: raise libvirtError ('virDomainCreateWithFlags() failed', dom=self)
Note : This compute node have single Network interface eth0 , So ihave changed in /etc/nova/nova.conf file in compute node is --flat_interface=eth0
