Re: [Xen-API] How to setup network with VLAN on bonding

[Rob Hoes <Rob.Hoes@xxxxxxxxxx>]

Hi Anthony,

It is possible to have a VLAN on top of a bond. To do this, first create the 
bond, and then create the VLAN on top of the bond master.

You would first need to create two Network objects (with Network.create): one 
for the bond and one for the VLAN. Then use Bond.create with the ref of the new 
bond network and refs of the PIFs that you are bonding, which will return a ref 
to the new Bond object. A bond master PIF object will be created as well; get a 
ref to this via Bond.get_master. Then create the VLAN by doing VLAN.create, 
giving it the second network you created, the bond master PIF, and the VLAN 
tag. Besides the VLAN object, an "untagged PIF" (a.k.a. VLAN master PIF) will 
be created, which will be connected to your VLAN network. Use 
VLAN.get_untagged_PIF to get a ref to this PIF. Finally, plug the untagged PIF 
using PIF.plug to make everything happen. Only now the actual devices are 
created in dom0, and your VMs can use the VLAN network.

Regards,
Rob
