Hello,
Does anyone knows when VT (''Vanderpool Technology'' or the new
name Intel
Virtualization Technology) enabled XEN version will be released?
Thanks, Arnon.

Greetings, On a similar note, does anyone know when processors with VT (Intel) for Pacifca (amd) will be generally available?

In VT mode, Xen and dom0 co-operate to simulate the rest of the devices of the PC platform - that code is in the current unstable tree. For full performance, you''d probably still install versions of the Xen device drivers once the domain was up and running, however. The code in the unstable tree can run an unmodified Linux install in a VT-mode virtual machine already. Further work is required to get Windows booting, since (IIRC) it uses a load of 16 bit cruft which is not currently supported. I''m not sure that Windows support will be available for 3.0 but it will become available eventually.

Steven, Cool. I don''t remember seeing that in the road-map page as part of the 3.0 new features list... Do you believe VT will simplify the execution of Windows OS XEN domain? I guess that until VT virtualizes the whole platform and not just the CPU (which we got with current VT), we will still need xend-Windows version.

"Ring -1" is basically root mode ring 0, which is what the hypervisor runs in.

Cambridgeには、VT enableのCPUがあると言ってますね。 うちにも欲しいですね。この際、VT-xでもいいから。 /* サーバ本)Linuxソフト開統 江藤 圭也 内線:7551-5740 */> -----Original Message----- > From: xen-users-bounces@lists.xensource.com > [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of MarkWilliamson> Sent: Friday, April 22, 2005 8:34 AM > To: Nils Toedtmann > Cc: xen-users@lists.xensource.com > Subject: Re: [Xen-users] VT/IVT enabled xen version > > > So for VT mode there is no VT CPU support (intel vanderpool or amd > > pacifica) necessary? > > Unfortunately, yes, you do need a VT CPU. > > > Afaik such processors are not available yet? > > They do exist but they''re not available to buy ;-) We have a number ofthem> in Cambridge.

Where can I download the 3.0 unstable tree from?
