Re: [Xen-users] How to install an HVM linux guest without bootcd?

[Goran Vukoman <xen-list@xxxxxxxx>]

Hi all,

thanks for answering. My goal to partitionate a file is to be flexible
in setting up a new virtual machine.

My steps in mind are so far...

1.A. Create an Image with "dd"
1.B. Partitionate it
1.C. Copy a bootloader into the MBR with "dd"

2.A Create an second Image with a size which is exactly the size of
image from 1.A MINUS 63 sectors.
2.B Format the image
2.C Install everything what is needed with debootstrap into Image
2.D Configure Image
2.E Overwrite Image from 1.A from sector 63 to end WITH image from 2.C

I hope it'll work

Thanks
