Just to add some other info.

I've tried to use the xend toolstack in the way suggested in the Xen wiki
and in this thread.
1. Disable SELinux (just in case...)
2. Removed libvirt-daemon-driver-libxml package (rpm -e --no-deps ...)
3. Enabled/started xend via systemctl
4. Rebooted the host

After the boot I've done some safety check:
$ systemctl is-enabled xend.service
enabled

$ ps -furoot | grep -i xen
root        31     2  0 17:20 ?        00:00:00 [xenwatch]
root        32     2  0 17:20 ?        00:00:00 [xenbus]
root       523     1  0 17:20 ?        00:00:00 /usr/sbin/xenstored
--pid-file /var/run/xenstored.pid
root       592     1  0 17:20 ?        00:00:00 /usr/sbin/xenconsoled
--log=none --log-dir=/var/log/xen/console
root       705     1  0 17:20 ?        00:00:04 /usr/bin/python -Es
/usr/sbin/xend

Then I've tried the following command (as root)

$ virt-install -v -c iso/CentOS-6.4-x86_64-minimal.iso --ram 1024 --disk
path=./images/test-c63_64-xen.img,size=10 --name test-c64_64 --graphics vnc
--debug

And I got the following error

libvirtError: POST operation failed: xend_post: error from xen daemon:
(xend.err 'Device 768 (vbd) could not be connected. Hotplug scripts not
working.')

Any idea?

Thanks,
