Maintaining Xen with FAI - Questions

[Mario Bischof]

Hello,

I've got several Questions about using FAI to install a Xen virtual  
Domain.

- First of all, what did you use to make custom kernels? I tried to  
use make-kpkg for generating xen dom0 and domU kernels, for the dom0  
kernel it works fine, I am using the xen hypervisor provided by the  
debian repository, that works ok together with homemade Dom0 linux- 
kernel.
Please correct me if I already have done something stupid at this time.

- If I install the whole xen-system by apt-getting it, i can start a  
FAI Installation with the initrd provided by the deb package and the  
xenu kernel i generated by myself, of course i have to install my  
domu kernel over the xen system installation, also not very clean,  
but i dont know how to build a .deb-package out of the xen-utils or  
the hypervisor when i compile it from source.  But if i try to use  
ONLY my domu kernel it doesnt start. XEND.log says "domain has  
crashed".  Building deb-pkgs from xen-source seems pretty advanced to  
me, because there are several make targets, dom0, domu and xen-utils  
with hypervisor,so how did you guys manage this?

- Is there any essential support I have to setup in my domu kernel to  
get FAI to start running without an initrd?? I've checked there is  
already NFS support built into my domU-kernel. But what else do i  
need to be ready to use fai with xen?

- Do you use seperate kernels for dom0 and domU? the debian pkg from  
official server installs one kernel for both. What are the advantages  
of using just one for both purposes?


Many thanks for all coming help.

Greetings
