It utilizes Nova network that has flat IPv4 networks defined. We later enabled IPv6 on a few compute nodes, and the VMs that were created on those compute nodes had an IPv4 address that we defined at creation and an IPv6 address provided by the local router, and worked fine. What we have encountered is if the VM is terminated and we reinstantiate the VM via snapshot, the IPv6 address is different than the original since the hardware address of the new VM is different. </span></p><p class="MsoNormal"><span style="font-family:"Courier New""> </span></p><p class="MsoNormal"><span style="font-family:"Courier New"">Since some of our lab tools require us to hardcode IP addresses, it would be beneficial to have static IPv6 addresses. I see where nova boot commands can specify both ipv4 and ipv6 addresses, but from what I read from the documentation and searching around, the network defined would require having ipv6 set up on it. I see where one can add and delete a network, but there is no modify available. I would like to know if I have missed seeing a command that can do this, or if adding the v6 info into the database and restarting compute nodes is a possibility.</span></p><p class="MsoNormal"><span style="font-family:"Courier New""> </span></p><p class="MsoNormal"><span style="font-family:"Courier New"">Thanks,</span></p><p class="MsoNormal"><span style="font-family:"Courier New""> </span></p><p class="MsoNormal"><span style="font-family:"Courier New"">Mike</span></p><p class="MsoNormal"><span style="font-family:"Courier New""> </span></p><p class="MsoNormal"><span style="font-family:"Courier New""> </span></p><p class="MsoNormal"><span style="font-family:"Courier New"">[syseng@seng216 ~]$ nova network-show syseng-net</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">+---------------------+--------------------------------------+</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| Property | Value |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">+---------------------+--------------------------------------+</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| bridge | br100 |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| bridge_interface | ens3f0 |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| broadcast | aaa.bbb.ccc.255 |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| cidr | aaa.bbb.ccc.128/25 |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| cidr_v6 | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| created_at | 2015-10-03T15:26:54.000000 |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| deleted | False |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| deleted_at | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| dhcp_server | aaa.bbb.ccc.129 |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| dhcp_start | aaa.bbb.ccc.130 |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| dns1 | 1.2.3.4 |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| dns2 | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| enable_dhcp | True |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| gateway | aaa.bbb.ccc.129 |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| gateway_v6 | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| host | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| id | dfb16f90-4a49-49f3-9319-acd22968d214 |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| injected | False |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| label | syseng-net |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| mtu | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| multi_host | True |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| netmask | 255.255.255.128 |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| netmask_v6 | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| priority | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| project_id | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| rxtx_base | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| share_address | True |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| updated_at | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| vlan | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| vpn_private_address | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| vpn_public_address | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">| vpn_public_port | - |</span></p><p class="MsoNormal"><span style="font-family:"Courier New"">+---------------------+--------------------------------------+</span></p></div></body></html>
