Xen devel - Jul 2008 - status on broken qcow boot in ioemu-remote?

Hi,

currently in Xen unstable qcow boot support is broken if using the 
ioemu-remote tree (at least for HVM). The BIOS tells:
------------
Booting from Hard Disk...
Boot from Hard Disk failed: not a bootable disk
FATAL: No bootable device
-------------
As I saw a bug report on this yesterday on the list, I wonder if 
somebody has already started debugging on this?
It would be nice if people would share their observations on the list.

So far we can tell that it works when using the embedded ioemu and I 
vaguely remember that it worked with direct kernel boot (but currently 
cannot reproduce this) and PXE boot.

Regards,
Andre.

Yes, there is a bug in this area.  It should be fixed in my latest
tree but that may not yet have made it out of staging.

The first commit which has all of the fix is this one:

   commit ecb9068ce70eced667eb7f0445dcb6e2506c2002

       Merge branch ''qemu''

Ian.

Ah, that is a good hint. I was not aware that there is a staging tree 
for ioemu-remote. I am using the xen staging tree, shouldn''t it somehow
automatically clone the ioemu staging tree then (insert staging in the 
QEMU_REMOTE line in Config.mk)?

That should work if you get the right resulting URL, yes.
