Etch. I finally succeeded so I'll post a little Howto. Maybe someone
with a better understanding of automake and C stuff knows a nicer way
but the ugly folder with the links to the different header files.
The start point is a Debian Etch with a running Xen (in my case it's the
xen-hypervisor-3.0.3-1-i386-pae package). If you're not using the PAE
version of the xen-hypervisor change the "apt-get source" line
accordingly.
First you will need to install a bunch of development packages
apt-get install build-essential libxml2-dev libncurses5-dev
apt-get isntall libreadline5-dev python-dev
Go to your home directory and install the Xen hypervisor sources
cd
apt-get source xen-hypervisor-3.0.3-1-i386-pae
Create a folder with a bunch of symbolic links. We will use this folder
libvirt to find the header files.
mkdir libvirt-include
cd libvirt-include/
ln -s /root/xen-3.0-3.0.3-0/xen/include/public/xen.h
ln -s /root/xen-3.0-3.0.3-0/tools/xenstore/xs.h
ln -s /root/xen-3.0-3.0.3-0/tools/xenstore/xs_lib.h
ln -s /root/xen-3.0-3.0.3-0/xen/include/public xen
ln -s /root/xen-3.0-3.0.3-0/linux-2.6-xen-sparse/include/xen/public/ xen/linux
Configure the dynamic linker that it will be able to find the libxenstore library
echo '/usr/lib/xen-3.0.3-1/lib' > /etc/ld.so.conf.d/i486-linux-gnu.conf
ldconfig
Hum, this really is the installation of Xen, hopefully you should be able
to download prepackaged version, including the development part to avoid this,
but I have no experience with Debian myself.
Go to your home directory, download an extract the libvirt source
package
cd
wget http://libvirt.org/sources/libvirt-0.2.3.tar.gz
tar xvfz libvirt-0.2.3.tar.gz
cd libvirt-0.2.3
Configure, build and install the libvirt
That is the standard process, but again using prepackaged versions
would be nicer. Also note that theorically libvirt should now be able
to compile and work without Xen support assuming QEmu (and possibly KVM
support in recent kernel versions).
CFLAGS="-fno-stack-protector -I/root/libvirt-include
-L/usr/lib/xen-3.0.3-1/lib" ./configure --with-xen --without-qemu
make
make install
Enable the Unix socket server for xend. Edit /etc/xen/xend-config.sxp and change the
line
#(xend-unix-server no)
to
(xend-unix-server yes)
I would also make sure the http server is desactivated this is a giant
security hole:
#(xend-http-server no)
Restart your Xen-Daemon
/etc/init.d/xend restart
If everything work you should see your running virtual machines when you enter
virsh list
Ideally we should find prepackaged version for most common OS, coming with
the OS or from trusted sources. I'm fine pointing to such repositories, and
providing instructions on how to install in the FAQ. And if the problem
is storage, I'm fine hosting packages on libvirt.org itself, I just need
a person willing to maintain the package for one year at least (i.e. providing
updates).
And as usual if there is portability problems and/or fixes, send them
to the list, I'm eager to get libvirt on new platform, new oses, and new
virtualization engines !
For example I'm wondering about -fno-stack-protector passed before, why
is that needed ?
