Re: [Xen-users] XEN 4.3.0 Complete Crash on Kernel vmlinuz-3.2.0-4-amd64

[Walter Robert Ditzler <ditwal001@xxxxxxxxxxx>]

Maik,

no patch at all is needed since XEN is fully included in the kernel. My
kernel config file works for 3.10.5. you can open that file with 3.10.8,
make menuconfig will then update the kernel config to the newer version
3-10.8.

what I do is going through the new kernel config file, since new features
have often "DEBUG" enabled. And I don't want DEBUG information in my
productive kernel (ex: WIF, LAN, ...).

If you want DEBUG information you have to, those you want, turn on.

My procedure is:

aptitude install fakeroot build-essential kernel-package fakeroot
cd /usr/src
wget [KERNEL_SOURCE].xz
tar -Jxvf [KERNEL_SOURCE].xz
cd [KERNEL_SOURCE_DIR]
cp [KERNEL_CONFIG_TEMPLATE] [KERNEL_SOURCE_DIR]/.config
make menuconfig
CONCURRENCY_LEVEL=$(getconf _NPROCESSORS_ONLN) fakeroot make-kpkg --initrd
kernel_image kernel_headers modules_image
--append-to-version=.[YOUR_VERSION]
cd ..
dpkg -I [KERNEL].deb

wget [XEN_SOURCE].tar.gz

cd [XEN_SOURCE_DIR]
./configure --enable-githttp --libdir=/usr/lib;
make -j $CONCURRENCY_LEVEL dist; 
make install

that's it from my side

Hi Walter,

question. Do I need to patch the original kernels (3.10.8 or 3.10.5) in any
way with files for xen?
Or is it just the .config file to compile with the original kernels and all
is good?

Can you please more elaborate on things needs to be done. Thanks a lot.

Cheers,
Maik
