Xen users - Apr 2006 - cannot build xen 3.0.2 with custom config

Hi

I still don''t understand how to build xen 3.0.2 with custom configs for
xen0
and xenU.
On this list I read to use:
  make KERNELS="linux-2.6-xen0 linux-2.6-xenU" world
And this works, however I cannot change configs here.
When I call the command above, it creates default-configs and when I change
them afterwards and run the command again, my configs are overwritten.
I found no way to build two kernels with custom configs.

The README file is no help either. Having two trees from the command above,
running "make dist" does NOT use those trees as stated but creates a
new
"linux-3.0-xen" folder.

Maybe these seem to be stupid questions, but I never compiled kernels myself
before xen and I only did for xen3.0.1 and xen3-testing. Things changed
since and I don''t seem to understand it. There is propably a correct
way to
tell build world to use my configs, but I cannot find it.

(BTW, what is the correct/recommended way to include old configs (from
xen3.0.1)? I see there is a option to load "old config" in menuconfig,
but I
assume it also loads settings from xen 3.0.1 which might have changes in xen
3.0.2... Is there a way to load only "real" kernel options and leave
all xen
3.0.2 settings intact?)

I feel a little lost.

Any help would be greatly appreciated.

Best regards,
  Steffen

Hi

Still problems...

I realized I forgot the error message.

What ever I try, I always get:

 *** Missing file: arch/i386/boot/bzImage
 *** You need to run "make" before "make install".

Needless to say, that I ran "make" instead of "make
install".

As always, any help would be greatly appreciated.

Best regards,
  Steffen

Sorry realized I didn''t do a reply to All

Stephen, did you try this yet?

Try a "make help" in the xen3.0.2 directory. It shows all the options
to
build. My recommendation would be:

make xen            *installs the Xen Hypervisor
make tools           * installs all the Xen tools

* create the DomU kernel
make linux-2.6-xenU-config CONFIGMODE=menuconfig
make linux-2.6-xenU-build
make linux-2.6-xenU-install
mkinitrd -v -f initrd-2.6.16-xenU.img 2.6.16-xenU

* create the Dom0 kernel
make linux-2.6-xen0-config CONFIGMODE=menuconfig
make linux-2.6-xen0-build
make linux-2.6-xen0-install
mkinitrd -v -f initrd-2.6.16-xen0.img 2.6.16-xen0

Then just modify the grub.conf file with the new Dom0 kernel and initrd, and
the DomU domains with the new DomU and it should work. I think it will take
a reboot though to get the new Hypervisor in place.

Slight typo:

It should be:
make install-xen
make install-tools

The way I have it below onles builds them and places them into the dist/.

There is still the "make dist KERNELS=linux-2.6-xenU" like options.

That will make it and install it to the dist/ and not hte entire system.

You should be able to use the make dist from above and just copy the old 
config file to the xenU/.config file. There are some differences in the 
.configs because of different kernels, but if you are comportable with your 
current congis then stick with them.

I just ran the "make linux-2.6-xen0-build" and it built and installed
into
dist/ fine. You might want to do a "make clean" just ot clear anything
else
out, or even re-extract from the xen-3.0.2-src.tar.gz to start clean. I know 
you''ve been working on this for a while now and maybe something is
messed
up. I''m not sure what to say, it works for me.

Keep us posted.

Ryan

It turned out to be a problem with my old config files.
Even though they work with 3.0.1, they somehow disturbed the build process
of 3.0.2.
Now I have reconfigured both kernels by hand again... :(
However, it''s building.

When it''s finished, I have issued:

make xen
make tools
make docs

make linux-2.6-xen0-config CONFIGMODE=menuconfig
make linux-2.6-xen0-build
make linux-2.6-xen0-install
make linux-2.6-xen0-dist ( <-- unsure about this )

make linux-2.6-xenU-config CONFIGMODE=menuconfig
make linux-2.6-xenU-build
make linux-2.6-xenU-install
make linux-2.6-xenU-dist ( <-- unsure about this )

I expect to have all regular files (kernels, modules, xen) in dist then.
Is there a recommended way to get the scripts and such, that I have
something comparable to the binary distribution?

Such that I can take it to my xen server(s) and just hit ./install.sh ?

Regards,
  Steffen
