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?

Thanks,

YuLing

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,

 Hi All,

>From openstack documentation, it seems that if we need to create routers in order to have two private network ping each other. However, I followed the instruction on the website http://docs.openstack.org/trunk/openstack-network/admin/content/l3_workflow.html, but still could not get the ping working through two private networks.

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?

Thanks,

YuLing
