Dom0 on mainstream linux kernel, when?

Dom0 on mainstream linux kernel, when?

[Marco Sinhoreli]

Hello Xen devel team,

Do you have some prevision about when the dom0 xen kernel will be in
mainstream linux kernel or updated for kernel releases > 2.6.18.x? I
am particularly worried  since others hypervisors/virtualization
software are updated or are in mainstream linux kernel. Any news about
this question?

Cheers,

Fedora has been doing work to get Xen guests kernels working on modern
kernels using the pv_ops support in mainline. In Fedora 9 there is i686
(already upstream) and x86_64 (add on patches) DomU support on 2.6.25

  http://fedoraproject.org/wiki/Features/XenPvops

The x86_64 DomU patches will be pushed upstream as soon as practical

The next plan is to get Dom0 kernls working for Fedora 10. Whether Dom0 
patches will get accepted upstream is an open question because they are
more complex than DomU support

In absence of Dom0 support, the 'xenner' project also provides the ability
to run paravirt Xen DomU kernels using KVM fullvirt if you're unable to 
switch the guest in question to a real bare metal kernel.

Regards,
Dan.
