For those interested in VT, both Apple and Dell now have VT enabled laptops with Intel Core Duo mobile procs. Apple also has a $1200 US iMac with a Core Duo CPU.

So Apples MacBook Pro will not support VT, and I cannot imagine that Dell has a hold on different Yonahs. Would have been great so have MacOS X and Windows running concurrently on a machine that looks like not having been assembled from garbage (okay, so much for outing). Seems like we still have to wait, since one of the next steppings of Yonah should support VT (now it is simply deactivated). If anyone here has different info, please correct me.

There is a note attached which says this: Intel Virtualization Technology requires a computer system with a processor, chipset, BIOS, virtual machine monitor (VMM) and for some uses, certain platform software, enabled for it. Functionality, performance or other benefit will vary depending on hardware and software configurations. Intel Virtualization Technology-enabled VMM applications are currently in development. Thats quite a lot of qualifications... BIOS being the major one probably. -- Nick Craig-Wood <nick@craig-wood.com> -- http://www.craig-wood.com/nick _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Thank you for the clarification, sorry all for the misinformation.

BIOS being the major one probably.The c''t magazine (where Dirk had his info from, obviously) has a test of that CPU (in a Samsung X60) in the most recent issue. It says that EMT and VT are missing from it, currently. by Töns -- There is no safe distance. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

All info given beforehand pointed to VT coming with Yonah. It was just that with announcement of shipping one ore two weeks ago Intel published new information saying that VT is included, but not activated with the current stepping. That is what heise online wrote; I did not verify, of course. :-) Dirk _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

As of 5.1.2005 Intel themselves state Yonah (Core Duo) to have VT enabled. So we have to wait for the MacBook Pro to find out what really is inside. I hate waiting ...

BIOS being the major one probably.So hypothetically, if I have a duo processor, and the BIOS has ''Virtualization Technology = ENABLED'', and ''cat /proc/cpuinfo'' has a ''vmx'' flag, I''m good to go firing up a VT-enabled Xen domain. Are there any quick docs explaining how to set one up? ja. -- Joe Ammond joe.ammond@edwardjones.com plug into her electric cool where things bend and break and shake to the rules _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
In response to this thread I'll add my observation... Intel has a document that lists the errata for a CPU... and I found a LOT of issues regarding VT on the Presler (vmread vmptrld vmcs, etc.): "Intel(r) Pentium(r) D Processor 900Δ Sequence and Intel(r) Pentium(r) Processor Extreme Edition 955Δ Specification Update" http://www.intel.com/design/Pentiumxe/specupdt/310307.htm The similar document for the new laptop chips: "Intel(r) Core™ Duo Processor and Intel(r) Core™ Solo Processor on 65 nm Process Specification Update" http://www.intel.com/design/mobile/specupdt/309222.htm I note a complete absence of errata (defects) relating the VT on the laptop chips... so it makes me wonder if they got VT perfect or what? Or just not documented yet (a document update is mentioned to be coming January 18, 2006)? The speedstep power saving mode seems to be a problem on the new Pentium D series... and it is 64-bit vs 32-bit. Maybe the two implementations of VT have nothing in common in regards to errata. Of course, I am curious if these BIOS workarounds mentioned in the Pentium D errata actually are implemented properly - I wonder if a series of Xen 'tests' could be devised to see if a particular BIOS has the required workarounds. Can you tell I've been doing too much reading about VT hardware lately :) ?

Only the upcoming Core Duo T2700 has VT checked as a certainty. and The documentation we''ve seen indicates the current Core Solo chips lack VT, though the feature may make it to the upcoming ultra-low voltage Core Solo U1300 and U1400 processors See the link for more!

Hello,
It seems that the shipping iMacs do have VT enabled. From dmesg on an
iMac Core Duo:
CPU features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE
MCA CMOV PAT CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON VMX
EST TM2 TPR
HTT: 2 cores per package; 2 logical cpus per package
CPU extended features: XD
The Virtual Machine Extensions ("VMX") flag, which represents the VT
support, is present.
