Open Stack

Eric,
Ghassen had posted the original query. Adding him to this email.

Ghassen,
As others have suggested can you login to VM say using VNC (From dashboard)
You may be able to further troubleshoot from there ...

Hi , Mandar .

I did have such problems before ,and I got things work at last . So ,I think my experience may have a little help.

If you can ping (or ssh) to the VM on your HOST ,but can not ping with other computer in the network, then this is the floating ip problem.
You should assign your VM a floating ip,so the outside world can talk to the VM (and also for the VM to talk to outside)

but if you can not even ping the VM on your HOST ,then you should check if the VM is really running. I mean ,the Dashbaord may tell you that the VM is successfully running ,but this is only telling you that the "Virtual Hardware" of the VM is running ,it can not guarantee that the Operation System of the VM is loaded correctly and been booted! So ,you may need to check your image and other things.

ps:
Can you Plesase paste your nova config about the network?

Hope my answer may have a little help .

regards!

Hi,
It is a single machine setup.
There is nothing what is abnormal in the nova-network.log file.
I configured my IPs staticly, and the IPs of VMs are assigned by FlatDhcpManager.

1.       Have you enabled logging ? Do you see any errors in nova-network logs ?

2.       Which network manager are you using ?

3.       Some details about your setup will also help (Is it Single machine setup ?)

Hi,
I install openstack essex on ubuntu 12.04.
everything seems running correctly,
I can launch instances with nova boot command and also from the dashboard, an IP inside the range is assigned.
The problem is that i can't ping or ssh the instances.
I have configured the groupsecure rules to allow ping and ssh but the problem persist.
any idea about that please ?
thx
