New XEN infrastructure

It is done. The new Xen infrastructure is finished, although it is not yet completely in unstable.

The main difference to the old one, the hypervisor and utils packages includes the complete version and an abi spec, just like our linux kernels. Also it is now possible to install more than one version of the utils at the same time. The userspace tries to find the correct tools for the running hypervisor.

The following packages are provided now:

• xen-hypervisor-3.0.2-1-$flavour
• xen-utils-3.0.2-1
• xen-ioemu-3.0

and from the kernel

• xen-linux-system-$kernelversion

The only missing thing is a selection of the correct hypervisor in update-grub.
