Re: [Xen-users] [Xen-API] Installing XCP from USB thumb

[<ray@xxxxxxxxx>]

I am sorry for being so dense, but I can't tell what is happening.

This is building a thumbdrive installation by using a Linux system to
construct the contents for the thumb drive?

The ISO is openned with 7-zip and three files are copied o the root of
the thumb drive.  What was it that YUMI put on the thumbdrive?

Can something similar be done from a Windows 7 system?

Here's how we did it (from my engineer):

What we did to get XCP install from a USB stick.
Step #1) Download all the things
YUMI. (I used 0.0.5.8 but any version should work) -
http://www.pendrivelinux.com/yumi-multiboot-usb-creator/
XCP install ISO - http://www.xen.org/download/xcp/index.html
Step #2) Plug in your USB stick (the rest assumes the drive is assigned
a letter of D:)
Step #3a) Run YUMI
Step #3b) Agree to the license Agreement
Step #3c) Select D: for YUMI Step 1
Step #3d) Select the option ?Try an Unlisted ISO? for YUMI Step 2
Step #3e) Browse to the downloaded XCP ISO from step 1 and select it for
YUMI Step 3
Step #3f) Mash create and wait.

At this point it is going to bloat things a little by having the full
iso on the USB stuck but who cares right?

Step #4) Open the ISO downloaded in Step 1 using your favorite archive
program. (I use 7-zip) Copy the folders packages.main and
packages.transfer-vm to the root of d:\ and finally copy the file
XS-REPOSITORY-LIST to the root of D:\

Step #5) PROFIT?

The scripts which create the Debian CD sets use
case "$MKISOFS" in
*xorriso*)
add_mkisofs_opt $CDDIR/../$N.mkisofs_opts "-isohybrid-mbr
syslinux/usr/lib/syslinux/isohdpfx.bin"
add_mkisofs_opt $CDDIR/../$N.mkisofs_opts "-partition_offset 16"
which I think is related to this.

I think it is basically doing isohybrid at creation time instead of post
processing. It seems (and this corresponds with my vague memory of
seeing the discussion on debian-cd) like it needs xorriso rather than
mkisofs (which IIRC is deprecated).

Ian.
