Xen users - Feb 2006 - SELinux + EVMS + Xen - anyone done it?

Hi, I have seen a few posts on the list from people who were working on 
this.  If anyone has succeeded can you please drop me a line with some 
notes on your boot process and the initrd creation process please?

I seem to have the bits all working individually, but I can''t quite 
figure out how to get Xen kernel to boot up and start my EVMS stuff 
under Gentoo.  At the moment I have been trying using the genkernel 
(gentoo script) created initramfs and initrd (had to patch it to get 
one).  Both seem to cause a kernel panic during boot.  I haven''t yet 
tried to use the Xen initrd, but I gather there are some issues using it 
with gentoo... ?

Any assistance gratefully received

Regards

Ed W

I''ve made one manually that does evms_activate and mounts the root
filesystem under Xen.

I sent various patches towards the maintainer of genkernel (Tim Yamin)
which would allow it to work with Xen, but he didn''t like some of them
too much it seemed.  Guess he''s not a Xen user.  So I eventually just
gave up and made an initrd by hand.

Making the initrd by hand isn''t hard, it''s mainly making sure
that
your binaries are compiled static and then whipping together a script
to mount your root partition and pivot_root to it.

Just to be clear.  The totally vanilla initramfs which is generated by 
the latest genkernel works fine with latest Xen stable.  The trick was

a) in the boot params
b) NOT adding a special ARCH=xen line for the genkernel

The boot params in particular need to be quite exact.  See previous 
email for what works for me

This at least *boots* into the kernel now.  I now have some problems 
running a XenU session, but they seem to be Python related...
