Knowing that most Windows versions don''t support paravirtualization (or "Enlightenment" in Microsoft''s speech) and that meaning that using them as Guest OSs on Xen (post 3.0) don''t take full advantage of the hardware (needing to be fully virtualized), Red Hat developed what they call "Paravirtualization drivers" ( http://www.redhat.com/rhel/server/advanced/virt.html ) for Windows to enhance those OS performance while running on Xen (under a Enterprise Linux 5.1 Dom0). My question is, will xVM Server support these PV drivers too? This message posted from opensolaris.org
We haven''t tried RedHat''s drivers on our dom0 (or by extension, xVM Server), and we haven''t heard any reports of others trying. Theoretically, if the drivers are supposed to work on a xen 3.1 hypervisor, they should work on our 3.1 dom0. In practice, things rarely work so smoothly because the hypervisor interface is not as stable as it should be. We have developed our own Windows PV drivers and we will be releasing these soon. We are actively working on the legalities of making them available for download. They''re in use already internally here and they work great. They''ll be worth the wait.

Oh, I see. Thanks for your quick reply! Aside from the Windows drivers, are you working on any other OS PV drivers? This message posted from opensolaris.org

The link just says "Red Hat will announce details on the availability at a later point in time." Their May 20th press release said the drivers were "several weeks" away.> We have developed our own Windows PV drivers and we will be releasing > these soon.

PV drivers were supposed to be implemented for S10 U6 (early fall release) DomU running at SNV_9(X) Dom0. If i am wrong , please, correct.> > ----------------------------------------------------- > Russ Blaine | Solaris Kernel | russell.blaine@sun.com > _______________________________________________ > xen-discuss mailing list > xen-discuss@opensolaris.orgThis message posted from opensolaris.org

Hello! That is wonderful news. Is there any way to get a heads-up when the drivers are finally released? I am very eager to try them out... This message posted from opensolaris.org

Sun has announced dates for the release candidate and final release now. I am eager to find out if the Windows PV drivers are going to be part of that release? If not, when can we hope to get access to them? Will it be possible to convert a HVM Windows guest OS to a PVM Windows guest OS, or do I need to reinstall the guest from scratch? -- This message posted from opensolaris.org
