Re: [MirageOS-devel] Xen VIF configuration for tap devices

I have defined 3 vifs with 3 different mac addresses for the 3 tap devices that I am using, and switch shows the same mac address (mac address of the first defined vif) assigned to both tap2 and tap3.

Another issue that I faced is, although I can ping switch vm, nothing appears on vifs and xenbr0 when switch starts a TCP connection to a remote controller (using TCPV4 create_connection function). This function works well for unix config.

Hi all,

I have a switch with three tap devices tap0 (for the controller connection), 
tap1, and tap 2 running on Xen.

What would be the right VIF configuration for Xen?
It would be pretty much the same configuration as your tap setup.  The Xen 
networking model is to expose a VIF ('virtual interface') in the guest and 
dom0.  Everything else from there is host setup and can be customised -- most 
commonly by adding a bridge to the outside world and adding the VIFs from the 
guests to that bridge so they can communication externally.

The xl setup fragment looks like:

     vif = [ 'bridge=xenbr0' ]
     vif = [ 'mac=c0:ff:ee:c0:ff:ee,bridge=br0' ]
