Marcus Sorensen created CLOUDSTACK-686:
------------------------------------------
Summary: Allow for same vlan on different physical nics
Key: CLOUDSTACK-686
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-686
Project: CloudStack
Issue Type: Improvement
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.0.0
Reporter: Marcus Sorensen
Fix For: 4.1.0
There was an email chain about this on the dev list... subject was "same vlan
on different nics". Would like to adjust the contstraint in table
op_dc_vnet_alloc named i_op_dc_vnet_alloc__vnet__data_center_id to allow for
the same vlan number to be used on different physical nics, by changing the
unique from just 'vnet','data_center_id' to
'vnet','physical_network_id','data_center_id'.
This can be handy for example if you run out of vlans and have the capability
to bring up a second layer 2 domain on a different physical nic, or have two
customers, each with their own router, creating guest networks on different
physical nics and want to use the same IP.
I'm not comfortable with updating the schema myself, as I don't understand all
of the upgrade process around it.
With this change, I'd also like to have
11fe086adab8e790018343252ed08aac9a27b1c6 rolled back (CLOUDSTACK-226). It was
added to work around this database constraint. I can do this portion if someone
can work with me on the database change.
