Centos7 does not able to ping internet (google.com/hotmail.com/etc)
I have Centos7 core(openstack "fuel-community-10.0.iso") VM is installed. This VM is behind firewall. DNS is properly configured in /etc/resolv.conf. NSLOOKUP is properly resolving domain names. However when I ping any external domain name it is not happening. Even I disabled selinux from /etc/selinux/config and rebooted VM. The same permission is given to windows machines and ping response is fine.

Which VM? Version? Are you using bridged networking or NAT (I'm guessing the latter)?
FWIW, here's a vbox bug report (which may or may not be relevant)...

I have a CentOS 7 VM in VirtualBox on Slackware --Current using a bridged adapter. I can ping internet sites without issue.
I don't have a solution to offer, but I can say that, whatever your issue is, it's local to your configuration.

Hmmm... perhaps have a look at /etc/nsswitch.conf and make sure that the name resolution service order is not causing the problem
Code:
grep hosts /etc/nsswitch.conf
