Re: mirage-platform commit on June 26

Hi Vincent,

Thx for porting to mirari.  I see how it is done now.  

I tried the mirage-skeleton version (B=--xen make).  A few things:

In the .conf file I had to change ip-use-dhcp to false.  Then with all the latest versions I see the same behavior - no packets make it back to the VIF.  If I revert your commit on June 26, I see arp pkts on the bridge as expected and I see them on the VIF as well.  However for some reason the mirage-skeleton version brings up all my VIFs with IP 10.0.0.2, instead of the ones I have used in the test (10.100.100.101 and 10.100.100.102).  If I can make it come up with the my IP addrs (or at least different IP addrs), then I think it will work as expected.

I am not sure why it crashes for you.  That's worrying.

I can't seem to reproduce Balraj's failure on my Ubuntu laptop.  I'll try
