Xend and xl are part of different toolstacks and should not be used
together. You should investigate why you have xend running, most
likely it shouldn't be.

Xen 4.2 and newer have the xl toolstack as default.
Xen 4.1 and older have the xend/xm toolstack as default.

See http://wiki.xen.org/wiki/Choice_of_Toolstacks for more info.
