INTRODUCTION TO INTEL® AES-NI AND INTEL® SECURE KEY INSTRUCTIONS
Por Gael Hofemeier (Intel)Publicado en 07/26/20120
Starting in 2010 with the Intel® Core™ processor family based on the 32nm Intel® microarchitecture, Intel introduced a set of new AES (Advanced Encryption Standard) instructions. This processor launch brought seven new instructions.

There is additionally an e-book which food the entirety Forever Body Transformation review, and with the aim of indicates you will certainly recognize I beg your pardon? To expect and exactly how to stipulate your very own goals. Using their Forever Body Transformation Plan, they will expound recently I beg your pardon? Dishes is really Pro-FBT and specifically I beg your pardon? Foods are normally Anti-FBT and the instrument to sustain your metabolic value operating in ideal degrees. And additionally the wonderful feature pertaining toForever Body Transformation is the actuality with the aim of it comes having a 60 days 100 % money back ensure assure, so you possibly will test it away instead of a few kind of complete sixty days and additionally return this in issue it is not in point of fact instead of you personally. Forever Body Transformation is a emphasis loss list with the aim of might aid folks who are having problems of being round. That imply with the aim of every time a a...
How to identify processors with EPT accessed/dirty bits
Por Tracy Camp1
I'm aware that software can check the IA32_VMX_EPT_VPID_CAP MSR to determine if the EPT table supports access and dirty bits...  However I would like to know how to identify a processor before I've purchased it that has this support. This is a common frustration I have with Intel parts - minor features vary quite a bit and don't seem to necissarily 'stick' in a linear progression of CPUID values due to various market differentiations.  Most of the time it doesn't matter too much, since most features are just an optimization for something that doesn't need to be implemented in software, however in this particular case, I'm not sure how to 'emulate' the lack of an accessed and dirty bit in the EPT tables of earlier EPT implementations in software.

Dear Sir/Madam, We have intel 10GbE Network Adapter X540-T2. Please guide me for the virtualization testing software for the adapter. I am new to this forum, also guide me that is this correct forum for the 10GbE network Adapter X540-T2. Reply me as early as possible. Thanks in advacne.  
Unexpected EPT Violations
Por Ralf H.1
Hi, we're currently working in a project that involves extending the KVM hypervisor. While running the VM, we sometimes get EPT violations that shouldn't be possible from our understanding of the Intel documents. The scenario is as follow (we use Intel VT with EPT enabled):All guest paging structures (i.e., the paging structures _inside_ the VM) are set to non-writable on the last EPT level. In other words, whenever the guest OS writes to a guest paging structure (e.g. to map/free a page), this triggers an EPT violation. Now, "occasionally" the following happens:The VM performs a normal read operation somewhere in memory (doesn't seem to matter where). This then yields an EPT violation and bit 0,  bit 1, and bit 7 are set in the exit qualification field, bit 8 is cleared. According to the Intel specification (Table 27-7), this means that the EPT violation was caused by the MMU setting the dirty or accessed bit in the guest paging structures. At first, this makes sense since these ar...
Technological migration and virtualization, are they complementary?
Por kcav@snet.net2
Rather than force a user to abruptly break away from routines that have become easy to perform, I think it might be a good idea to run Windows 7 in a virtual environment on the new platform; provided it is possible to hotkey from the new work environment to the old, and back to the new in a New York minute.   My interest in this came about when after changing from an old fashion notebook to an Ultraboook with a Touch screen I discovered the Start menu has changed, of course.  Also, I realized that using a slow browser on a fast platform doesn’t make sense, so I left behind my beloved IE8 with iGoogle homepage and changed to speedy Google Chrome.  Then I found myself wondering how to save Favorites, block pop-ups, establish and maintain trust relations, all things I had become somewhat familiar with doing, and now have to consciously think about again.  I am looking forward to making greater use of audio and video processing capabilities in the new 64-bit environment.  Since A/V file...
vmx-preemption timer inaccuracy (across vmx transitions)
Por Michael L.1
Hi, From what I understand, the VMX-preemption timer should only decrement when in VMX non-root operations. I have been trying to use it as a way to measure cycle time in a VM, with respect to the running time of that VM. Hence, I do not want to include in my measurement the time spent in the VMM or the time to perform VM entries/exits. VMX-preemption timer seems like it could serve that purpose (with the granularity of the TSC to VMX-preemption timer ratio). However, in my test, the VMX-preemption timer seems to also decrement while performing VM entry/exits. My test: a) from the VMM: read the VMX-preemption timer in the VMCS b) VM enter c) VM exit *immediately after VM enter* (eip set to the hlt instruction) d) from the VMM: read the VMX-preemption timer in the VMCS (processor setup to save the VMX-preemption timer to VMCS on VM exit) the difference between (d) and (a) should be zero or a very small value since the VMX-preemption timer should only be decrementing when executing i...
