Re: [Xen-devel] domU networking trouble in Xen 3.0-unstable.hg

["Bryan D. Payne" <bryan@xxxxxxxxxxxx>]

I have just tried to upgrade to changeset 7572.  I discovered that  
doing a 'make install' after my update blew away my dom0 and domU  
kernel configs!  Unfortunately, I didn't have those saved off  
anywhere (my mistake), so I have spent the past four hours (and  
counting...) trying to recreate a working config.  I shall save this  
one when I finally get it working, but I'd like to suggest that  
perhaps a make install doesn't blow away .config* in the kernel  
source directories ;-)
Anyway, in the mean time, here's some additional information about my  
setup before attempting the upgrade.
* When I first posted about this problem I was using changeset 7398.

* The additional network config information that people requested is  
below:
