Error creating domain: vbd: Segment not found
Hello

i'm trying to build a xen guest on fedora core (Fedora Core release 3.92
(Pre-FC4)). i have installed xen with yum + yum update (following
http://www-128.ibm.com/developerworks/linux/library/l-xen/) but after
rebooting on xen0, i failed to create one guest:

# xm create mon1 -c
Using config file "/etc/xen/mon1".

Re: Error creating domain: vbd: Segment not found [ In reply to ]
to be sure, i tried to create more /dev/loop* device like said here
http://lists.xensource.com/archives/html/xen-fr/2005-04/msg00011.html
(french)

but with no luck

is there any way to debug/trace this kind of problem ?
this is the first guest on the box and it seems there is no reason to
failed. i try to build another base filesystems with yum and get the
same error.
