[Xen-devel] new /etc/xen/network script

I''m proposing to checkin the attached new /etc/xen/network script.
I''m
hoping it will be more robust to the various network startup problems
people have seen by using vendor ifup/ifdown scripts.

Please can people try it out, particularly if you had problems with the
old script.

If the script does fail for you, /var/log/xend.debug may have some
useful info. Please try to dig around to try and understand what has
gone wrong. I''ve attached the output of ifconfig before and after
starting xend for comparison.

We''re still awaiting patches to enable interfaces other than eth0 to be
specified in xend-config.sxp, so if you''re primary interface is eth1
edit the default ''netdev'' parameter at the top of the file.

Thanks,
Ian
