Hi
I gave the new Xen-4.6rc2 a spin on a CentOS 7 virtualisation guest
(nested-xen). I haven't yet started testing guests, but rather looked at
the install itself.
One issue, I found, was with xenstored.service and the corresponding
unit-file:
[root@xencen7ws ~]# systemctl status xenstored
xenstored.service - The Xen xenstore
Loaded: loaded (/usr/lib/systemd/system/xenstored.service; disabled)

As you can see, xenstored.service is running, but disabled by the
package installation. This is, because xenstored.service apparently got
overseen in the source-rpm's spec-file's post runtime/preun runtime. See
diff [1] for details.
Also, I think xenstored should write a pidfile. You might consider
adding to /usr/lib/systemd/system/xenstored.service:
PIDFile=/var/run/xenstored.pid
and change
ExecStart=/usr/sbin/xenstored
to
ExecStart=/usr/sbin/xenstored --pid-file /var/run/xenstored.pid
$XENSTORED_ARGS
Hope this helps, this is just a quick start. I'll continue checking and
reporting during the next days.
Regards,
Thomas
