Hi,
For example right now my domU won't boot off the hard disk. I experimented
by removing the hard drive from the disk line. The result was the same. So
now I do not know if the bios can't see my hard drive or it just can't boot
my hard drive. A simple list of detected sata drives would save me loads of
time.
For HVM guests, there is quite a bit of information logged to
/var/log/xen/qemu* logs.
Do you see anything there that might help?
Also, could you post your domU config file, and as suggested by Jerry Amundson:
log file entries, stdout messages, etc? These really do help in
debugging the situation.
Also, you didn't mention your version of Xen, how it was installed,
your kernel versions etc.
A quick comment on your general comments on Xen: Xen already has a lot
of attention from
a lot of people. The distros, and other big third parties have taken
Xen under their wing and
there are a lot of really professional software on and around Xen.
I would recommend taking a look at the xen.org site, which is
currently under re-design, but
will still give you a better sense of where Xen is and, where it has
been, and where it is going.
Hope that helps,
Cheers,
Todd
Hey thanks for the response. I was sending the information but this is
the first email that seems to have hit the list. Such goes the way of
things, none the less I'll compile all the information.

P.S. I do not see it talking to the hard drive in the logs.
