Unable to ping to an instance launched in openstack.

Question

I have installed open stack using devstack. Launched an cirros image. I can connect to the instance from VNC console but unable to ping to the instance.

Answer 1

You should configure your security group to allow incoming ICMP (ping) traffic, and also TCP port 22 (ssh). You can configure the security group from the Openstack web dashboard.

Answer 2

I agree with Barak's answer. For reference - here are shell commands to configure rules:

$nova --no-cache secgroup-add-rule default icmp -1 -1 0.0.0.0/0
$nova --no-cache secgroup-add-rule default tcp 22 22 0.0.0.0/0
