due to vnc connection is required by vnc-viewer, vnc-viewer can present 
the graphical console,
because there is no paravirt framebuffer patches applied to 
xen-unstable, so virt-manager can't work
with xen-unstable for paravirt guests, because we can't get the 
graphical console run. is it right?

xen-unstable should be the latest version of Xen, if it has no paravirt 
framebuffer patches, maybe xen-stable
should have no either? and if so, we may say virt-manager not support 
paravirt at the moment?
