libvirt users - Apr 2014 - Not able to start a VM - Xen and libvirt

Hello,

I've installed Xen 4.3.1 on a machine with x86 based 64-bit Intel processor
running Fedora 20 (Linux 3.11) and libvirt 1.0.1.

I'm not able to start a VM. It's failing with the below mentioned error.
What am
I doing wrong? If this is documented somewhere, a pointer to that would be
great.

I did a "generic" search, but in vain, before posting to this list and
I
couldn't find an easier way to search through the mailman archives of this
mailing list.

Thanks for your time.
