It sounds like you want #3 or #4. -- Thanks, Matt __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev

Re: [openstack-dev] [nova][neutron] boot server with more than one subnet selection question
Hi, You can choose which subnet (and even IP address) should be used, see „fixed_ips” field in [1]. If You will not provide anything Neutron will choose for You one IPv4 address and one IPv6 address and in both cases it will be chosen randomly from available IPs from all subnets.

[openstack-dev] [nova][neutron] boot server with more than one subnet selection question
I have a network created like below: 1 network with 3 subnets (1 ipv6 and 2 ipv4) ,when boot, whether I can select subnet to boot from or the subnet will be force selected by the order the subnet created? Any document or code can be referred?
