Hi all,

I am looking for advices on debugging a Mirage unikernel with multiple tap 
devices for the following problems:

1. The same MAC address is assigned to all tap devices.
Could you please provide more details about the xl file you used to create the 
vif?  Did you set the `mac=xx` in the .xl file?

vif = [ 'mac=00:86:3E:51:27:4B,bridge=xenbr0','mac=00:86:3E:51:27:4C,bridge=tapbr1','mac=00:86:3E:51:27:4D,bridge=tapbr2' ]

A one-to-one assignments of tap devices to vifs is necessary for the proper operation.


2. Calling TCPV4 create_connection function produces no traffic on virtual 
interfaces.
A small reproducible program demonstrating the problem would help here.

I found that this happens when NETWORK "listen" function is called on tap1 and tap2 devices. It looks to be a consequence of the first problem.
