The files in this directory

-livecd.ks.in
+p2v.ks.in
Kickstart file which describes how to build the live CD. This is
essentially the configuration file for livecd-creator. Most
importantly it lists the RPMs which are needed on the live CD.
-livecd-post.sh.in
+virt-p2v
- This is the %post-configuration section of the Kickstart script. It
- is a shell script which runs after the RPMs have been installed but
- before the live CD is turned into an ISO. The shell script creates
- any extra files we need on the live CD.
-
-p2v.init
-
- This is installed on the live CD as /etc/init.d/p2v, and it causes the
- live CD to boot into the P2V configuration tool (see next).
-
-virt-p2v.sh
-
- This is the virt-p2v.sh P2V configuration tool itself. It is
- installed on the live CD as /usr/bin/virt-p2v.sh and runs after the

+Tips for OCaml
+----------------------------------------------------------------------
+
+All the packages you need are in Fedora and Debian.
+
+If using emacs, make sure you install tuareg-mode (the editing mode
+for OCaml). Unfortunately there is no Fedora package for it at the
+moment, but it is very easy to install.

General implementation plan
----------------------------------------------------------------------
For (b) we can simply use 'dd' and 'ssh'. The general plan is to do
this:
- dd if=/dev/disk | gzip | ssh xenhost 'zcat > /var/lib/xen/images/disk.img'
-
-If the user doesn't have sshd installed on the Xen host, then they can
-also opt for a pure TCP transport:
-
- dd if=/dev/disk | gzip | nc xenhost port
-
- and on the remote host they do:
- nc -l port > /var/lib/xen/images/disks.gz
+ dd if=/dev/disk | ssh -C xenhost 'cat > /var/lib/xen/images/disk.img'
For (c) we can use device-mapper snapshots to mount a ramdisk above
the disks themselves. This allows us to make non-destructive changes
to files, and still see the "modified" block device (d). A hairy
-shell script looks for candidate files to modify.

-Non-generic virt-p2v
-----------------------------------------------------------------------
-
-The above describes the generic virt-p2v, which asks users questions
-after boot. It is also possible to build your own live CD, based on
-virt-p2v, which has various settings compiled in so it runs
-automatically.
