Here's another feature... I'm not sure if anyone else will need this,
but we had a requirement to log all console output, and to have
console windows available at all time and potentially multiplexed
between users. I solved it by having each xen domain start up in a
persistent window inside a screen session.

My (gentoo) xendomains start() and stop() currently look like:

start() {
        einfo "Starting ${AUTODIR} Xen domains"
        if [[ ${SCREEN} == "yes" ]]; then
                screen -d -m -S xen -t xen-cbc0
                screen -r xen -X zombie dr
                logrotate -f /usr/share/xen/xen-consoles-logrotate
                screen -r xen -X logfile /var/log/xen-consoles/%t
                screen -r xen -X logfile flush 1
                screen -r xen -X deflog on
        fi
        # Create all domains with config files in AUTODIR.
        for dom in $(ls ${AUTODIR}/* 2>/dev/null); do
                name=$(get_domname ${dom})
                if ! is_running ${name} ; then
                        ebegin "  Starting domain ${name}"
                        if [[ ${SCREEN} == "yes" ]]; then
                                screen -r xen -X screen -t ${name} xm
create ${dom} -c
                        else
                                xm create --quiet ${dom}
                        fi
                        eend $?
                else
                        einfo "  Not Starting domain ${name} - allready running"
                fi
        done
}

stop() {
        einfo "Shutting down ${AUTODIR} Xen domains"
        # Stop all domains with config files in AUTODIR.
        for dom in $(ls ${AUTODIR}/* 2>/dev/null); do
                name=$(get_domname ${dom})
                if is_running ${name} ; then
                        ebegin "  Stopping domain ${name}"
                                xm shutdown --wait ${name} >/dev/null
                        eend $?
                else
                        einfo "  Not Stopping domain ${name} - not running"
                fi
        done
        if [[ ${SCREEN} == "yes" ]]; then
                screen -r xen -X quit
        fi
}

It should be easy to adapt this to the generic script if others find it useful.
