onward, not forward.

Ah, progress!  Thankfully, this problem seems to be fixed in both Solaris Express and OpenSolaris, so I guess we can take out this section.  I'm pretty happy about that, yeah.

Devices and Hotplug

Solaris' hotplug system may give you some trouble. The problem is that the default hotplug configuration (in 2008.05) doesn't react correctly to the Xen virtual devices. This causes domain creation to fail with an error message like "Device 0 (vif) could not be connected. Hotplug scripts not working."

To fix the hotplug scripts, create and run a script like the following, which adds appropriate rules for Xen devices:¹

BASEDIR=${BASEDIR:-/}

/usr/sbin/syseventadm list -R $BASEDIR -c EC_xendev > /dev/null 2>&1
if [ $? -ne 0 ]

then
/usr/sbin/syseventadm add -R $BASEDIR -c EC_xendev \
/usr/lib/xen/scripts/xpvd-event 'action=$subclass' \
'domain=$domain' 'vdev=$vdev' 'device=$device' \
'devclass=$devclass' 'febe=$fob'
fi

/usr/sbin/syseventadm list -R $BASEDIR -c EC_xpvsys > /dev/null 2>&1
if [ $? -ne 0 ]
then
/usr/sbin/syseventadm add -R $BASEDIR -c EC_xpvsys \
/usr/lib/xen/scripts/xpvsys-event 'subclass=$subclass' \
'shutdown=$shutdown'
fi

# restart daemon if the package is being added to the running system
if [ "$BASEDIR" = "/" -a $? -eq 0 ]
then
/usr/sbin/syseventadm restart

fi
