Dear All,
I have checked the status of Selinux in both the servers & tried to deploy.
Current Status of node:
[root at nc1 ~]# getenforce
Disabled
Current Status of front:
[root at front ~]# getenforce
Disabled
Tried to create a VM from front using this command:
[oneadmin at front ~]$ onetemplate instantiate "CentOS-6.5" --name "myvm1"
VM ID: 23
[oneadmin at front ~]$ onevm list
ID USER GROUP NAME STAT UCPU UMEM HOST
TIME
23 oneadmin oneadmin myvm1 runn 0 512M nc1 0d
00h05
Output of /var/log/one/23.log
[oneadmin at front ~]$ tail -f /var/log/one/23.log

*Wed Jun 25 02:13:30 2014 [LCM][I]: New VM state is UNKNOWN*
Wed Jun 25 02:13:35 2014 [VMM][I]: VM found again, state is RUNNING
Why the state should be Running & Unknown at the same time? Any clue?
Although it is running & I could login to that VM doing simple ssh <IP
ADDRESS>
