I''m working on adding the 802.1Q vlan suport to Xen. Half of the work
is done. The idea is that we can specify something like this on the domU
configuration file:
vlan = [ ''pdev=eth1, vlanid=123, bridge=xenbr1123'',
''pdev=eth1, vlanid=100 '' ]
perhaps even specify an IP address (I founded this usefull in some
implementations), and then, as allways:
vif = [ ''bridge=xenbr1123, mac=00:16:3e:00:00:00'',
''bridge=xenbr1101, mac=00:16:3e:00:00:01'' ]
and perhaps also specify a list in xend-config.spx.
I''ll check if the bridge is already created before connecting the VIF,
at domU creation, if not bring it up, and when destroying the domU, also
check if other domU is using the same bridge before shuting it down.
All this raises me some questions:
- Suggestions/advices regarding on where/how put my code?
- Could it bring problems if I add this code in
''xen/xm/create.py''?
gopts.var(''vlan'',
val="iface=IFACE,vlanid=VLANID,vlanbridge=VLANBRIDGE",
fn=append_value, default=[],
[...]
- Other suggestions/advices?
best regards

I guess you want to connect vlan 123 from a trunk on eth1 to xenbr1123. And the next line? Why not just use the linux way and create vlan interfaces? e.g. # vconfig add eth1 123 # vconfig add eth1 100 and then put eth1.123 to xenbr123 and use this?> perhaps even specify an IP address (I founded this usefull in some > implementations), and then, as allways:What''s the purpose of the IP here?

If I have systems I move host between, I put the same network config configuration on them by design. Especially on such machines I do not want any script/tool to fiddle with my network configuration, but YMMV.

In my particulary case I''m developing a solution to an ISP that provides the VM with some other services like IP PBX, file servers, etc., that integrates to the client LAN, and instead of using firewalls and routers to separate clients, they use VLANS, the customers can buy their VMs via a web page, and all the process must be automatic all that plus some other are the reasons why I''m doing such effort as add this kind of behavior to Xen.
