+=================================

+* Need to include the following line in /etc/fstab:
+    none /proc/xen xenfs defaults 0 0
+
+* Need to place the file 'xendomains' (created in init.d) somewhere useful. 
+  Fedora use /usr/libexec which Arch does not have. It's a script so maybe 
+  /etc/xen/scripts/ ?
+
+* Error messages about 'failed to execute /usr/lib/.... xend/udev_event'
+  (lots of them) are caused by /etc/udev/rules.d/xend.rules
+  As xend is (a) deprecated and (b) not used, it is safe to remove xend.rules
+
+  I was able to remove /etc/udev/xen-backend rules without any (apparent) effect.
+
+* The AUR build creates both oxenstored and censtored. oxenstored is more
+  efficient according to xen.org so oxenstored.service is provided.
