Hello,

xend automatically mounts /proc/xen, but it doesn't try loading evtchn or 
xen-evtchn modules.
Should we add automatic loading of these modules? 

xend doesn't start if xen event channel functionality is missing.

Fedora Xen rpms do load modules automatically, like this:

# cat /etc/sysconfig/modules/xen.modules
#!/bin/sh

test -d /proc/xen                               || exit 0
test -f /proc/xen/capabilities                  || mount -t xenfs xen /proc/xen
test -f /proc/xen/capabilities                  || exit 0
grep -q "control_d" /proc/xen/capabilities      || exit 0

for module in xen-evtchn evtchn blkbk netbk; do
        modprobe ${module} >/dev/null 2>&1
done

-- Pasi
