Network name parameter while creating a instance using nova boot command

[Shashwat Srivastava]

While creating a new instance in a setup where you have multiple networks. System gives error
"ERROR (Conflict): Multiple possible networks found, use a Network ID to be more specific. "

In this case if user remembers the network name but not the id, then he has to run 1 more command (neutron net-list) to get the network id.

I think we should add the support to include network name to be given with the nova boot command like
nova boot --nic net-name=TestNetwork

Usually this error occurs only if the given name is ambiguous. If multiple network names match the specified name, you will get the conflict error. It should work if the specified name can uniquely identify one network.

Can you give an example of the names of the multiple networks you have and the net-name you requested?

I am talking about case when you run this command to boot a vm.

nova boot --image cirros-0.3.4-x86_64-uec --flavor m1.small test1

and you have 2 or more networks.
Then system throws a error as stated in bug description.

And then to run the command we have to add the parameter "--nic net-id=" to attach the vm to a specific network.
I suggested in place of --nic net-id= can't we have "--nic net-name" variable where putting the name of the network will be easy as compared to getting the id of the network after running another command.

I think we can use network name when we are booting an instance. But instead of nova boot we have to go with openstack server create command in which you can pass network name (--nic net-id=private). And this support should be developed for nova boot command also. I verified on liberty version. Please correct me if i am wrong.

I think you can specify a network name with nova boot like this example:

  nova boot --image cirros-0.3.4-x86_64-uec --flavor m1.nano --nic net-name=private --poll hello

Here is the documentation, by the way:

http://docs.openstack.org/cli-reference/nova.html#nova-boot

which can also be seen by running 'nova help boot'

Thanks for that. Just now verified in mitaka version it is working fine using --nic net-name=network-name. Earlier we tried in liberty nova help boot shows but it didn't work.

I too raised the bug as I was working on Liberty release.

If it there in Mitaka release its well and good.
