I am using three nodes to do the installation, and I am using the openvswitch plugin with the vlan mode, do I need to do some configration in the physical switch?

one possible reason can be that your VM didn't get IP address from its DHCP server. Can you check your VM instance log (You can check it from dashboard) and see whether its sending the DHCP request for IP and getting any response from it

Hi,
I've installed openstack using quantum by the guide 
https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/master/OpenStack_Folsom_Install_Guide_WebVersion.rst
everything works fine, but I can't ping vm from the outside world, neither from the network node.The following is some of my configration.
1) root@networknode:/etc# ip netns 
qrouter-8f5f3c17-a00e-4382-a403-181dfbb9d189
qdhcp-e58739ff-16dc-4289-8110-242f7818d314
2) qrouter and qdhcp server is up
