Openstack Dashborad does not add a network card to the virtual machine, but the backend is the interface of this line.
First we create a virtual machine, this virtual mechanism 11.11.11 the network segment
Then view the current network with several network segments
Next we create an interface for the 192.168.1 network segment
You can see that the newly created port ID is 8add52c1-3ad6-4651-b1fb-d142fc60b58c
Next we will add this interface to the virtual machine, first check our virtual machine
Then add the port you just created to the virtual machine, and then look at the port of the virtual machine to see that there are two different network segments of port
At this point we log on to the virtual machine to see, we can see the network card added successfully, but did not give the IP
Modify a configuration file under Cirros system/etc/network/interfaces
Then reboot the virtual machine to do it, such as:
Add network card to this success
