domU.sh: This script builds a Slackware domU guest.

After the ordeal of installing, configuring and booting Slackware XenLinux,
you might be wondering how to load a guest OS. If you look around, you can
find Xen domU (unprivileged) guest images to download from the Internet, but
some of us might want to roll their own.

Start by mounting Slackware DVD to /media/SlackDVD and run:

  ./domU.sh

This script will install Slackware into 8GB file called slackware.img and a
also create 500MB swap file called swap_file.

Once the install is complete, have a look at the "mydom" file. Fill in the
full path to slackware.img and swap_file, and run:

  xl create -c mydom

Your Slackware XenLinux domU should boot instantly.

Getting the best performance out of your domU is usually done with trimmed
down kernels. Here are a few things to (de)select when building such kernel:

  Processor type and features  --->
    [*] Paravirtualized guest support  --->
      [*]   Xen guest support

  Bus options (PCI etc.)  --->
    [ ] PCI support

  Device Drivers  --->
    < > Serial ATA and Parallel ATA drivers  --->
    SCSI device support  --->
      < > SCSI device support

Removing SCSI device support will expose /dev/xvd* block device names, and
prevent "XENBUS: Waiting for devices to initialise..." error.

These files are not intended for production enviroment use, and should serve
only as a good starting point.
