How do you reserve fixed IP's?

I've got nova-network setup in multi-node setup with it auto-assigning fixed ip's;

fixed_range=10.0.0.0/24

As a side question, how do you add additional fixed ranges?

Thanks for any help!

Hi, you could try nova fixed-ip-reserve <Your fixed ip> to reserve an IP from being used by Nova when launching an instance.

Coming to your side question, you could try something like nova-manage network create private --fixed_range_v4=192.168.100.0/24 --bridge_interface=br100 to create additional fixed ranges.
