Re: Wheezy & Wheezy XEN Kernel Different ?

Thanks,

Was a rough week.. I did reinstall and did see it was the xen-4.1-amd64.gz hypervisor file. I was somehow reading the presentation as the hypervisor was now integrated into the kernel.. That's what happens with deadline and no sleep. :)

thanks

Are you perhaps confusing the Xen hypervisor binary (package) with the
Linux kernel binary (package)?

Xen is a type I hypervisor, that means it runs directly on the bare
metal. The dom0 Linux kernel runs as a guest kernel under it.

In the past Linux needed special patches to run on top of Xen (and hence
there was a special xen flavour of the Linux kernel packages in Debian
in Squeeze and before) but this is no longer the case in Wheezy and the
standard Linux kernel flavours work as a guest under Xen too. It is this
aspect I was referring to in that talk.

The Xen hypervisor contains very few drivers, the majority of the
peripheral hardware is driven by the dom0 kernel or, if you wish, by
specialised driver domains.
