You could probably get away with updating the network_type in the database. That said if you are switching from gre to vlans you'll end up having downtime so it probably makes more sense to write a script that recreates the networks using vlans instead with the same mac and port info rather than figuring out how to change the db.<br><br>Aaron <br></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Tue, Oct 15, 2013 at 10:15 AM, Geraint Jones <span dir="ltr"><<a href="mailto:geraint@koding.com" target="_blank">geraint@koding.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="font-size:14px;font-family:Calibri,sans-serif;word-wrap:break-word"><div><div><div>Thanks for that, reading it makes me think I will need to update at least some stuff.</div><div><br></div><div>Okay so an example of one of my current networks looks like this :</div><div><br></div><div><div>+---------------------------+--------------------------------------+</div><div>| Field | Value |</div><div>+---------------------------+--------------------------------------+</div><div>| admin_state_up | True |</div><div>| id | 51efc95c-3791-4ca7-ad83-47a0e9b1d550 |</div><div>| name | Application Servers |</div><div>| provider:network_type | gre |</div><div>| provider:physical_network | |</div><div>| provider:segmentation_id | 7 |</div><div>| router:external | False |</div><div>| shared | False |</div><div>| status | ACTIVE |</div><div>| subnets | 2caa6e3c-45ce-4021-9afa-19133c0d4b5e |</div><div>| tenant_id | 59a2d92051fe417f90539622d61951d0 |</div><div>+---------------------------+———————————————————+</div></div><div><br></div><div>Clearly those will not come up post migration,</div><div><br></div><div>Do I just need to do quantum net-update 51efc95c-3791-4ca7-ad83-47a0e9b1d550 —provider:network_type vlan —provider:physical_network physnet —provider:segmentation_id 107</div><div class="im"><div><br></div><div>?</div><div><div><div>-- </div><div>Geraint Jones</div></div><div>Director of Systems & Infrastructure</div><div>Koding </div><div><a href="https://koding.com" target="_blank">https://koding.com</a></div><div><a href="mailto:geraint@koding.com" target="_blank">geraint@koding.com</a></div><div>M (NZ) <a href="tel:%2B64%2022%20123%204626" value="+64221234626" target="_blank">+64 22 123 4626</a></div><div>M (US) <a href="tel:%2B1%20415%20316%208027" value="+14153168027" target="_blank">+1 415 316 8027</a></div></div></div></div></div><div><br></div><span><div style="border-right:medium none;padding-right:0in;padding-left:0in;padding-top:3pt;text-align:left;font-size:11pt;border-bottom:medium none;font-family:Calibri;border-top:#b5c4df 1pt solid;padding-bottom:0in;border-left:medium none"><span style="font-weight:bold">From: </span> Rahul Sharma <<a href="mailto:rahulsharmaait@gmail.com" target="_blank">rahulsharmaait@gmail.com</a>><br><span style="font-weight:bold">Date: </span> Monday, 14 October 2013 11:02 pm<br><span style="font-weight:bold">To: </span> Geraint Jones <<a href="mailto:geraint@koding.com" target="_blank">geraint@koding.com</a>><br><span style="font-weight:bold">Cc: </span> openstack <<a href="mailto:openstack@lists.openstack.org" target="_blank">openstack@lists.openstack.org</a>><br><span style="font-weight:bold">Subject: </span> Re: [Openstack] Migration from OVS-GRE to OVS-VLAN<br></div><div><div class="h5"><div><br></div><div dir="ltr"><div>Hi Geraint,<br><br></div><div>You missed one line which also needs to be added:-<br></div><div>bridge_mappings = physnet:br-eth1<br><br></div><div>Here, br-eth1 does the similar kind of task which br-tun was doing in GRE mode, but with different internal working.
