Binaries
----------------------------------------------------------------------
Binaries are available from the website (live CD images which can be
burned directly to a CD and booted on the p2v candidate machine).

-
-Building
-----------------------------------------------------------------------
-
-Requirements:
- * livecd-creator (on Fedora the package is 'livecd-tools')
- * qemu (only for testing)
-
-(1) Edit Makefile - there is some general configuration at the
- top which you may want to change.
-
-(2) 'make build' will build an ISO image called virt-p2v-$VERSION.iso
+ http://et.redhat.com/~rjones/virt-p2v/download.html
-(3) Burn the image on to a CD using standard tools.
-Booting from USB device
+Usage
----------------------------------------------------------------------
-If you wish to boot from a USB keydrive, use the livecd-iso-to-disk
-tool:
-
- livecd-iso-to-disk virt-p2v-$VERSION.iso /dev/sdX1
+Please read the manual page:
-(Replace /dev/sdX1 with the actual USB device).
+ man virt-p2v
+or make man; nroff -man virt-p2v.1 | less
+or http://et.redhat.com/~rjones/virt-p2v/virt-p2v.1.html
-In my experience I also had to set up a suitable MBR:
- cat /usr/lib/syslinux/mbr.bin > /dev/sdX
-
-Running
+Building
----------------------------------------------------------------------
-Boot the candidate machine from the live CD or USB keydrive.
-
-You will need to have network access to another machine where it will
-save the virtual disk images. Ideally that machine will have ssh
-access (sshd service running), but there is also a simple network
-daemon that you can run on the target machine. Note that the target
-machine is usually the Xen host, but it doesn't need to be: you could
-copy the images to a staging machine, and later copy them over to the
-Xen host.
-
-Note that the live CD doesn't modify any data on the candidate
-machine.
+Requirements:
-Answer the questions. There is a tutorial and explanation of some of
-the questions on the website which you may wish to follow:
-http://et.redhat.com/~rjones/virt-p2v/
+ * livecd-creator (on Fedora the package is 'livecd-tools')
+ * ocaml, ocaml-extlib, ocaml-pcre, ocaml-xml-light (all in Fedora)
+ * qemu and/or KVM (only for testing)
-While the live CD is booted a shell is available on other virtual
-consoles. Go to a virtual console using [ALT] [F2] and log in as root
-with no password.
+(1) Edit Makefile - there is some general configuration at the
+ top which you may want to change.
-If it works, the result will be disk images for each filesystem from
-the candidate machine, which should boot directly or with the minimum
-of changes.
+(2) 'make build' will build an ISO image called virt-p2v-$VERSION.iso
-Booting P2V candidate under Xen
-----------------------------------------------------------------------
+(3) Burn the image on to a CD using standard tools.
Testing
$ cp /var/lib/xen/images/rhel5gax32fv.img .
$ make boot HDA=rhel5gax32fv.img
qemu -m 512 -cdrom virt-p2v-0.1.iso -boot d -hda rhel5gax32fv.img

-
-TCP transport and network daemon
-----------------------------------------------------------------------
-
-The preferred transport is ssh, but if you cannot use this then there
-is an alternate TCP transport. (This transport is not encrypted).
-
-On the Xen host or staging server, install NetCat (the 'nc' command,
-in Fedora and RHEL the package is also called 'nc').
-
-Choose a free port number and make sure that it is not firewalled.
-
-Then run:
-
- nc -kl PORT > disks
-
-where PORT is replaced by the port number chosen above.
-
-After p2v has completed the 'disks' file will contain compressed
-images of one or more disks. There is a Perl script called
-virt-p2v-unpack which can unpack the file:
-
- virt-p2v-unpack disks
