Able to ping VM's fixed ip's from network node, not from controller node

asked 2013-04-09 18:01:30 -0500

Hi,

i have a 3 node setup (controller,network and compute). i am able to launch instances and instances are getting fixed dhcp ip's no issues on that part. But i am unable to ping those fixed vm ip's from controller node except the gateway ip(50.50.1.1) in that subnet. i have already added a route for that subnet(50.50.1.0/24) through router gateway. Also Nat'ed ip's also doesnt seem to be pinging.

all iptables Nat rules looks good. i am wondering what could be the problem. please let me know what log is needed.

This route is the same that you mentioned:

ip route show 10.0.0.0/26 dev br100 proto kernel scope link src 10.0.0.1

ip route -n 10.0.0.0 0.0.0.0 255.255.255.192 U 0 0 0 br100

10.0.2.2 is the router's IP of your external subnet?

Yes, I have configured the rule to security group, I tried with: nova secgroup-add-rule default tcp 22 22 0.0.0.0/0 nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0 But I continue with the same problem My instance has: vmnet=10.0.0.10 but I can't access to them: $ ping 10.0.0.10 From 10.0.0.254 icmp_seq=1 Destination Host Unreachable 100% packet loss

In your oppinion that suggest me..
