Since there isn't an rpm for the xenstore tools for guests, copy libxenstore.so.* and /usr/bin/xenstore-read (and the rest, if you want) to the guest and use something like this:


let i=1

while [ $i -le 100 ]; do
        NAME=$(./xenstore-read /local/domain/$i/name 2> /dev/null)

        [ -n "${NAME}" ] && break

        let i++

[ -n "${NAME}" ] && echo ${NAME}

exit 0

I don't see why you would even need this, though. If you are using kickstart, you can get the hostname with either the static configuration or DHCP.
