[Xen-devel] News - Microsoft Submits Drivers for Paravirtualization
I don''t normally news-post, cross-post, or even post to devel at all, but I thought this was quite interesting. Apparently, Microsoft submitted 20,000 lines of device driver code for inclusion in the staging kernel. Perhaps this is a step towards paravirtualized Windows guests in Xen? That would be quite compelling. http://www.networkworld.com/news/2009/072009-microsoft-linux-source-code.html Best Regards Nathan Eisenberg Sr. Systems Administrator Atlas Networks, LLC _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

No, this seems to be a step in positioning Hyper-V to be the market leading hypervisor by making Linux run as a guest on Hyper-V. I don''t see this as any sort of good news from a Xen standpoint. Perhaps I missed something that made you think otherwise?

I''d bet there isn''t sufficient info. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Re: [Xen-devel] Re: [Xen-users] Xen viridian support/features
Uhm, just to get clear in this topic, the great work of James is not that useful as it supposed in this thread. It leaks reliable support for exactly those Windows Versions with best Hyper-V integrations. So there is the choice to exploit Hyper-V guest integration services or absolutely ugly hacking around in a win2008 x64 guest policies with a real great chance to get the guest perfectly and unrecoverable meshed up. So it would be great at least to have things like shutdown notification out of the box, as it will be with an viridian interface implementation. Again if xen provides a feature using viridian API win2008 x64 guests would use it without ANY modification.

Furthermore this won''t include a back channelYes thats right when the system shuts down xm shutdown is called, I don''t know what happens if a guest fails to shutdown, myself I''d probably want it to be xm destroyed after a timeout as thats probably what I''d end up doing anyway, I could easily modify the script for you so that after trying xm shutdown it sends xm trigger <domid> power to any remaining domains and if any still fail to shutdown I could make it destroy them. Its something I looked into and could do in few minutes, I just didn''t bother because all of our servers have remote kvm and 99% of reboots are supervised, but let me know if you''d like me to make a patch for you.
