Thanks Ashok. I've already executed the following two commands:
nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0 nova secgroup-add-rule default tcp 22 22 0.0.0.0/0 However, it still didn't help. I can see that vm1 can ping vm2's gateway, and vice versa. Just vm1 could not ping vm2. Could it be cirros issue? Will it make any difference if I use a different vm image?

Hi Yuling, You may need to check the security group rules , ensure that the security group allows ICMP and ssh(22) in case you are looking for ssh access, Regards, Ashok On Sat, Jun 15, 2013 at 7:10 AM, <yulin...@dell.com<mailto:yulin...@dell.com>> wrote: Hi All, >From openstack documentation, it seems that if we need to create routers in >order to have two private network ping each other.

Here is what I did: 1. I'm using the Vlan mode for OVS network type. 2. I created one network net1 in one subnet. 3. I created another network net2 in another subnet. 4. I created a router and attached the two subnet interfaces to the router. 5. I created two VM instances on net1 and net2 respectively. 6. However, I still was not able to ping from vm1 to vm2. Any idea?
