[Xen-users] Finally cracked the mystery of motherboards with Vt-d support
After contacting Asus, MSI and Gigabyte, this is what I got back. Only motherboards with the QXX chipsets and certified with the Intel VPro support the Vt-d virtualization technology. I''m not sure about MSI though, because this is what I got from their support: "Almost board could support. Please refer to our website, http://www.msi.com/product/mb/." The problem is that QXX chipset are only used for mini and micro ATX motherboards with very few expansion card slots making the Vt-d kind of useless. -- Mgr.

Re: [Xen-users] Finally cracked the mystery of motherboards with Vt-d support
Some Intel motherboards have VT-d (made by Intel, not MSI/Asus/etc). I have an Intel S5520HC mobo which supports VT-d and has enough expansion slots... You might want to take a look at it http://www.intel.com/products/server/motherboards/s5520hc/s5520hc-overview.htm 2011/5/20 "Mgr.

And btw. the situation on Intel boards is the same. Only QXX chipsets with VPro support Vt-d. -- Mgr.

Core i7 processors have ton more features and are much more suited for this environment. -- Mgr.

The only major differences is that Xeons have 2 QPI buses in order to accomodate dual-processor setups and have ECC support, while the only place where i7 really shines compared to Xeon is TurboBoost, especially when activated on all 4 cores. http://www.cpubenchmark.net/high_end_cpus.html However, I can understand that the price difference might be a definitive factor in your choice... as ECC ram and the CPUs themselves are quite pricey. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

You can get a complete list of VT mainboards here http://www.intel.com/support/motherboards/desktop/sb/cs-030922.htm On 05/20/2011 02:56 AM, "Mgr.

But according to Intel employees Vt-d should work on motherboards that are not listed there. -- Mgr.
