Installing a Scripts guest on a Xen host
----------------------------------------

You need to create the volumes to use:

    lvcreate -n $MACHINE-root --size 50.00G $HOST
    lvcreate -n $MACHINE-swap --size 10.00G $HOST
    lvcreate -n $MACHINE-cache --size 11.00G $HOST

/-------------------------------------------------------------------\
    Note: If you need to manually format the the swap and cache
    partitions (for example, you are migrating a host from 'migrate'),
    these commands should work.  If in doubt, consult the kickstart.

        # Use fdisk to generate a DOS partition table, and a single
        # partition extending the entire volume.
        fdisk /dev/$HOST/$MACHINE-swap
        fdisk /dev/$HOST/$MACHINE-cache
        # Figure out what kpartx is going to make the devices as
        # (e.g. $SWAP_DEV and $CACHE_DEV)
        kpartx -l /dev/$HOST/$MACHINE-swap
        kpartx -l /dev/$HOST/$MACHINE-cache
        # Read out the partition tables
        kpartx -a /dev/$HOST/$MACHINE-swap
        kpartx -a /dev/$HOST/$MACHINE-cache

        # FORMAT!
        mkswap $SWAP_DEV
        mkfs.ext4 -O ^has_journal -m 0 -N 1000000 $CACHE_DEV

        # Remove the devices
        kpartx -d /dev/$HOST/$MACHINE-swap
        kpartx -d /dev/$HOST/$MACHINE-cache
\-------------------------------------------------------------------/

Make sure that the console has an entry for this host:

    vim /etc/conserver/conserver.cf

If it doesn't, add:

    console $MACHINE {
        master $HOST;
        include xen;
    }

We use Kickstart to to initial Fedora configuration.  Installing a new
vanilla machine is as easy as:

    xm create scripts-server machine_name=$MACHINE install=fXX && console $MACHINE

The only prompt (near the beginning of the install process) should be
for the root password, and at the end, when it asks you to reboot.
Say yes, and the machine will power down, and then restart without
the install parameter:

    xm create scripts-server machine_name=$MACHINE && console $MACHINE
