Hi Neil, Thanks for your reply.
I have done tcpdump on dhcp port of the private network in Openstack and I saw the received dhcp request and replies. It seems tgat the replies are not received to the VM. I want to add tgat if I adjusted the ip manually inside the VM instance , it works fine and I can ping the dhcp ip 11.0.0.2 in my case. I hope this info shows you where could be the problem I have.
