Every time I Launch an image other than cirros from Horizon, i get an error "No valid hosts". This time I thought id try doing it from the command line.

Questions.

What are the minimum arguments required to launch an error free instance?

I used : nova boot --flavor m1.tiny --image cirros-uec command_line_VM but this launched into an error state.

How do I assign it an ip address when (I assume) I do not have neutron installed (how are the other VMs in horizon assigned IP addresses?).

If you are not having neutron then it would be nova-network coming in picture so i guess the command "nova network-list" will come in handy.. Now when it comes to booting a VM you need the following things:-

  1. Flavor
  2. Network
  3. Name of VM
  4. image which VM will use

The command which I use is :-

nova boot  --image <Image-id> --flavor <Flavor_id> --image <IMAGE_ID> --nic net-id=<Network-id> <VM_NAME>

To get details you have to use the following commands:-

nova flavor list
neutron net-list
glance image-list

This is the most helpful answer for beginners I have ever seen.
