Description of problem: In correct, this is not a bug. In [5.2. Creating guests with virt-manager] directory in screenshot at 7. The Assigning storage space window displays. is "/xen/images/rhel5ORApv.dsk", If it is in /var/lib/xen/images (its for SELinux environment), it's better.
I'm sorry to rush. I missed Note below the image. I close this.
