Hello,
we have a strange problem on a fresh install of CentOS 6.5. On the
server we want to use Xen to host paravirtualised guests (the system has
no hardware virtualization support). To manage the domain we would like
to use libvirt. Xen and libvirt are set up as described here:
http://wiki.centos.org/HowTos/Xen/Xen4QuickStart
http://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt
When we try to create a new domain this does not work. In
/var/log/xen/xend.log we have to the following error:

Any help is appreciated.
