Hello all, 
(cc'd Jared, the author of XenCD)

I have moreover a general question regarding the construction of XenCD.

As you probably know, XEN does not yet support USB. Although, with a
new BIOS I am able to boot the XEN cd from my usb stick using the same
image - a pure cp -Ra xencd/* /mnt/usb/.

Now, since I cannot mount a usb stick to the /dev/sda* it becomes more
complicated to start other example domains as available on the CD
(there is no /boot/<kernel>).

Reverse engineering the image by taking the user space ram disk, unzip
it and mount it through a loopback device gives me access to the
filesystem which I can modify. However, the disk is too small so I
need to use 'dd if=/dev/zero of=...' to make another image which I
copy the entire existing FS to, compress it and then try to boot from
it.

This does not work - kernel panic. Could someone please get me some
instruction on how this work?

Thanks in advance
- Eivind
