Hello, I have a victoria cluster. I am a bit perplexed about OpenStack networking and was wondering if you could enlighten me on the topic. 1. bond When configuring bond interfaces (bond0/1/2/3) in an OpenStack instance, can I follow the same steps as I would on a physical machine? Are there any particular considerations to keep in mind? Also, when it comes to switch configuration, do I configure virtual machine switches directly or are there specific OpenStack interfaces to use? 2. `openstack port create --network net1 --no-fixed-ip port_net1` I was able to obtain a port with an ip_allocation value of "none" using the above command. I noticed that the ip_allocation value can be set to "none", "deferred", or "immediate". Is there a CLI interface to modify the ip_allocation value of a port, for example, changing "none" to "deferred"? Alternatively, what is the recommended method to make this change? 3. Is it possible for users to set IP addresses within an instance system? For example, if I create an instance without an IP address, is there a mechanism that allows me to set an IP address within the instance system, or can I only modify the port bindings or switch ports externally to change the IP address of an instance? Thank you for your attention to this matter. Best regards, Han Guangyu
