Yeah, but I think support ipv4 and ipv6 both is more reasonable. -----邮件原件----- 发件人: Sean Mooney <smooney@redhat.com> 发送时间: 2025年1月5日 12:40 收件人: Alex Song (宋文平) <songwenping@inspur.com>; openstack-discuss@lists.openstack.org 主题: Re: Nova create vm with special ipv4 and ipv6 as far as im aware nova has never supprot creating a port with dual stack ipv4 and ipv6 adddress an passign fixed ip for both. if you want to do that you shoudl create the port with both adress first via neutron using the openstack port create command and then pass the port uuid to nova when creating the vm i.e. openstack server create --port <port uuid> ...

Hi Nova team, does nova support create vm with special ipv4 and ipv6?
As port create with ipv4 and ipv6 works by:
openstack port create 111 --network 10851e96-8995-4988-b819-0514b38d7353 --fixed-ip subnet=a564ac90-3ff3-47d7-8ae5-20e2666eaa3c,ip-address=172.24.4.54 --fixed-ip subnet=afa3c858-c3d3-4784-8964-2c46840b714d,ip-address=2001:db8::183
but vm create with ipv4 and ipv6 with the cmd
openstack server create --flavor 1 --image 62254c92-a579-4c8a-a2f4-f2624cef8ec1 --nic net-id=10851e96-8995-4988-b819-0514b38d7353,v4-fixed-ip=172.24.4.53,v6 -fixed-ip=2001:db8::188 test
raise exception:
openstack server create: error: argument --nic: Invalid argument net-id=10851e96-8995-4988-b819-0514b38d7353,v4-fixed-ip=172.24.4.53,v6 -fixed-ip=2001:db8::188; either 'v4-fixed-ip' or 'v6-fixed-ip' should be specified but not both.
So why nova doesnot support?
