[xen-tools] feature requests

[elw at stderr.org]

some things i ran into when bringing up our first xen domain:

1) it'd be great if xen-create-image checked to make sure that dom0 has
    the loopback module loaded.  i'm embarassed to say that i didn't, and
    didn't realize it until things blew up ;)

2) when building a sarge guest, we need some more device nodes.
    /dev/sda2 didn't get created in my fresh guest, so it couldn't swapon.
    `MAKEDEV sd` fixed it, of course, but doing it pseudo-automagically
    would be very nice.  it should be possible to parse this stuff out of
    the domU config file and take care of the common cases without hassling
    the user.


Hope these are useful suggestions / quasi-bug-reports.
