Re: [Xen-users] Xen 3.0 (release) Debian packages?

[Ralph Passgang <ralph@xxxxxxxxxxxxx>]

The problems with the "backend device not found" or "hotplug script not 
working" was completely my mistake and had nothing to do with the packages.

Xen 2 used "xen-br0" als default bridge device. Xen 3 usses "xenbr0" and I had 
still some old configs with xen-br0.

It would be great if the /etc/xen/scripts/* would give better debugging 
output. If the output was something like: "xen-br0 not found" then I would 
have found the mistake a lot faster.

the packages are available at:

 http://packages.debianbase.de/<distro>/i386/xen3/ and
 http://packages.debianbase.de/<distro>/i386/xen3-pae/

and are working quite well...

I still would like to get some feedback, if someone is willing to test them, 
here a short howto:

1) simply add:
 "deb http://packages.debianbase.de/<distro>/i386/xen3 ./"
OR
 "deb http://packages.debianbase.de/<distro>/i386/xen3-pae ./"
to your /etc/apt/sources.list file. Repleace <distro> with either sid, sarge 
or etch.

then installing xen3 is very easy: "apt-get update && apt-get install xen".

only the linux-xen-patch package doesn't work (at the moment, I am working on 
it), so compiling a kernel is not "the debian way" for now.

add: "deb-src http://packages.debianbase.de/sources/xen3 ./" 
to /etc/apt/sources.list and type: "apt-get update && apt-get source xen".

Then changedir in the new xen3.0.0 directory and type:
"make linux-2.6-xen-config CONFIGMODE=menuconfig"

and then either: "make linux-2.6-xen-install" or use make-kpkg in the 
linux-source dir for building a kernel package.

Feedback is very much appeciated.
