Re: [Openstack] How to make Neutron select a specific subnet when boot an instance
There has been some work on this [2], but it didn't make it into the Kilo release (abandoned), and I don't see it either in later releases. [2] https://blueprints.launchpad.net/nova/+spec/selecting-subnet-when-creating-vm Zitat von Hang Yang : Hi there, I have one question about choosing a specific subnet when boot a vm. My OpenStack cluster is in Queens and I have multiple subnets in one network. What I want is when I issue a boot command the instance only gets ip from one subnet by default. I know there is a way to achieve that by creating a port with --fixed-ip subnet=xxx then pass the port id to boot command. Wondering if there is another way that does not need manually create the port? Is there any configuration I can do to make it default for Neutron to only pick one subnet from a network in boot? Thanks for any help.

Re: [Openstack] How to make Neutron select a specific subnet when boot an instance
Hi, depending on your workflow there would be a way with scripting [0], not sure if this would be a suitable approach for you. There also has been a blueprint [1] for the selection of subnets during instance creation since Juno, but I can't find anything about an implementation.
