Pike version of Openstack virtual machine command line specified ip address example analysis, in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

View the existing network interface (corresponding to the virtual machine Nic)

#. Admin-openrc

By viewing admin permissions, you can see more tenant id tenant_id.

Create a network interface with admin permission to specify the tenant, the ip address, and the corresponding network

Add a connection, and if you do not specify a port-id, you will create a new

Can ping, add the specified ip is normal.

This is the answer to the sample analysis question about the ip address specified by the command line of the Pike version of Openstack virtual machine.
