Fedora xen - Aug 2006 - i386 paravirt guest fails to create during install

I''ve been trying to keep up with the current fedora rawhide release but
I have run into some problems creating guest domains and can''t seem to
find any resolution.  
The following errors lead me to believe that there is a configuration
issue on my system, but the strange thing about this is that I can start
a FC development version just fine (granted I have block disk issues
later in the install), but any previous release of FC that includes xen
(5, 5.90) fail.  I''m not sure if I have come across a problem with Xen
or if its a /cough user error perhaps someone could help me figure
out????  ;-)
 
Another note side note, selinux is disabled, and I am running everything
current as of rawhide this AM (8-1-2006)
 
[root@localhost tmp]# rpm -qa | grep -i xen
xen-libs-3.0.2-22
xen-3.0.2-22
kernel-xen-2.6.17-1.2462.fc6

[root@localhost tmp]# uname -r

[root@localhost tmp]# getenforce
Disabled

I get the following error when trying to create a domain...
 
[root@localhost ~]# xenguest-install.py -n fc-devel -s 8 -r 1024 -f
/data/fc-devel.img -l
http://127.0.0.1/pub/redhat/fedora/linux/core/5/i386/os
 

Starting install...

I''ve looked through the failures when creating the domain in the
xend.log and can not seem to figure out what it is referring to as the
problem....

I''ve also tried creating an xml file and using virsh to create the
domain, but still get the following...
 
virsh # create /tmp/foo.xml
libvir: Xen Daemon error : POST operation failed: No such domain
fc-devel2
Failed to get devices for domain fc-devel2
error: Failed to create domain
 

virsh #

 
 
Any help is appreciated

Due to switching to using PAE kernels for x86, you unfortunately can''t
create an FC5 guest from a rawhide host.
