[Xen-users] WORKAROUND : Re: Ubuntu Gutsy Xen problems : DomU n/w not working

[jd <jdsw2002@xxxxxxxxx>]

Thanks a lot to Todd Deshane.

take a look at these. I think my solution was to get
rid of network manager and add in an entry in
/etc/network/interfaces, but there may also be a more
elegant solution that others proposed.  
https://bugs.launchpad.net/~deshantm?field.searchtext=xen&orderby=-importance&search=Search&field.status%3Alist=NEW&field.status%3Alist=INCOMPLETE_WITH_RESPONSE&field.status%3Alist=CONFIRMED&field.status%3Alist=TRIAGED&field.status%3Alist=INPROGRESS&field.status%3Alist=FIXCOMMITTED&field.assignee=&field.bug_reporter=&field.omit_dupes=on&field.has_patch=&field.has_no_package=

I added the following to my /etc/network/interfaces
auto eth0
iface eth0 inet dhcp

And rebooted the machine. (could have possibly just
started the network services and xend)

Will test some more.
