Xen users - Jul 2006 - xen, 64bit, gentoo, hardened kernel - no chance?

Hi,

 

is there any chance to get xen gentoo as DomU under amd64 x2 with hardened
kernel running?

I always get the error that its unimplemented (don’t know wheter that’s from
hardened or gentoo in general)

 

When I want to config my DomU kernel on my own, do I need any XEN DomU 64bit
patches, or can I use a normal kernel as I would get with “emerge
gentoo-sources”

 

Thanks in advance,

 

Mit freundlichen Grüßen

Jürgen Ladstätter ( jl@pics.co.at )

It''s still unclear to me where you want to have the hardenend amd64
kernel. In domU or dom0? what do you mean by "under"?

What''s unimplemented? Where does this error arise?

Either I did''nt understand your question, or the answer is that it
should be obvious when reading the manuals.

Please try to take some more time to describe your problem precisely
(but still trying to keep it short, which is sometimes hard, I know)

Hi,

Gentoo Hardened Kernel in my domU.
Amd64 x2 is the cpu which is used by the system.

The error occurs at this point:

GEN1 linux # make && make modules_install
CHK include/linux/version.h
CC arch/x86_64/kernel/asm-offsets.s
arch/x86_64/kernel/asm-offsets.c:1: error: code model `kernel'' not
supported
in the 32 bit mode
arch/x86_64/kernel/asm-offsets.c:1: sorry, unimplemented: 64-bit mode not
compiled in
make[1]: *** [arch/x86_64/kernel/asm-offsets.s] Error 1
make: *** [prepare0] Error 2
GEN1 linux #



I hope you see now what i mean.
Simple compiling any kernel with gentoo as domU doesn’t work!

I think your kernel build system (gcc et al)  doesn''t support
compiling 64 bit code.
I had something similar Debian sarge, too, could only build xen 64 bit
kernels on etch amd64.

Please ask the gentoo Mailing lists on how to build 64 bit Kernels.

Henning

If the toolchain is screwed up, it most likely happened when it was
installed.  Did you install with a 32-bit install CD and not amd64?

Hi,
i installed the gentoo domU image from jailtime.org and just emerged
hardened-sources.
So I didn’t make any choice wheter 32 bit or 64

It''s probably not built for amd64 with multilib.  I recommend starting
with your own filesystem and stage1.  That''s what I do for all of my
VMs.  (Actually, I make a single minimal image that I copy to all of
them as a base, but essentially they are all begotten from a stage1
tarball.)
