Open Stack

Hi Li,

Thanks for the response. This really resolved my issue of launching the instance.

One issue I am seeing now is my instance is showing the IP - 123.0.0.14 [ demo subnet ] in dashboard but I am not able to see the IP address on eth0 of guest VM.

I tried manually getting the IP using dhclient but seems like dhclient is not installed in cirros tiny flavour image.

Can you help resolve this issue?

Thanks
Chetan Bali

Hi,

I don't know the error in dashboard.
But this looks like nova can't create directory:
OSError: [Errno 13] Permission denied: '/var/lib/nova/instances/6bde1525-5c72-4d5d-815e-1205ed0e6bde'

Check yourdirectory :
        ll /var/lib/nova/instances/
If it looks like:
        drwxr-xr-x 6 root root     4096 Jan  6 14:44 ./
Edit it:
        Chown -R nova:nova /var/lib/nova/instances/

Thanks.

Subject: [Openstack] unable to launch instance on icehouse 3 node setup

Hi,

I have a setup with 3 node architecture with [ 1 controller + 1 compute + 1 network node ].

My services are in running state for all nova and neutron.

When I try to launch a instance from demo user, I am getting "no valid host found" error in dashboard.

While seeing nova-compute.log in compute node, I see following errors:
