Re: [Xen-users] Xen 4.0.1 rc3 pre install problem
http://bderzhavets.wordpress.com/2010/06/17/hackery-xen-4-0-1-rc2-source-kernels-packaged-for-ubuntu-lucid-virtualusr-site/
I have limited experience with packaging above.
With xen-4.0_4.0.1rc3-0ubuntu1.diff.gz xend should start without clean up.

This may or may not address your problem but it worked for Ubuntu systems with a
similar requirement, build once and distribute.
Apply the attached patch (not mine) to xen 4.0.1.rc3.pre and then build using:
export KERNELS="" ; export PYTHON_PREFIX_ARG="" ; make dist
This generates a dist dir that puts everything in the right place for Ubuntu systems. I know the sysconfig/default changes apply to debian as well, the ones I'm not sure about are the python lib location move.
This patch works for 4.0.0 and 4.0.1.rc3.pre, but not 4.1.

Guys,
I've successfully ran dom0/domU (both Debian) in my local laptop using 2.6.32.15 dom0 with xen-4.0.1-rc3-pre. Great. Now I want to install it into couple of test-machines without compiling from source. So I did following..
a. make dist-xen
b. make dist-tools PYTHON_PREFIX_ARG="--install-layout=deb"
c. make dist-stubdom
This should pre-pare my dist/ directory with binaries. With the help of top-level /.install.sh I should be able to install it any other machine (same ARCH=x86_64/amd64). I've tar-zipped, copied and inflated. The target machine is a CentOS 64-bit machine whereas the build machine (my laptop) is a Debian/Ubuntu 10.04 64 bit one. After installation, my xend started, bridge-magic happened, `brctl -show` is fine, xm info / xm list is fine, ls /dev/xen is fine (evtchn,gntdev) too. But when I'm trying
to run a domU (using a working domU-xmexample-config) it has some problem with tap driver config and complains
"ValueError: need more than 1 value to unpack"

vmlinuz/initrd/core.img/swap.img are made on Ubuntu and just copied over.
The same config worked earlier on a ubuntu-dom0/ubuntu-domU setup. Is this something to do with CentOS-dom0/Ubuntu-domU? Is copying binaries (pyc) built in Ubuntu wrong? Then how even xend/xendomains got started? If xend started with same python tool chain, what's wrong with domU booting up?
Please help me guys. Should I re-compile?
-Thanks
