but ESXi 5.5 has just been announced ( albeit it's not shipping ) ...
Either way, thank you for clarifying this matter!
I sure hope this feature is present on the 5.5 release.
ESXi 5.5 will not have support for hardware VMCS shadowing on Haswell processors.
Is there a KB or document that provides information on which versions of ESXi support various Intel/AMD virtualization features?
I'll try to put something together. Is there a particular feature you're interested in?
Thanks! This is a great resource! I'm not looking for any specific feature, rather looking for a guide (like the one you created) that could help us when selecting Intel processors that contain specific Intel VT features that VMware supports. That way when we find we'll benefit from specific feature(s), knowing VMware's support for them will drive which processor(s) we ultimately select.
Any good guide you've found that helps map the Intel-VT features to specific Intel processors on the market? That's the final piece of the puzzle for me.
Enabling Intel® Virtualization Technology Features and Benefits I/O Hardware Assist Features of Intel® Virtualization Technology for Connectivity (Intel® VT-C)
Virtual Machine Device Queue The Virtual Machine Device Queue (VMDQ) feature is a hardware assist in the Intel networking silicon that improves data processing
performance by improving throughput and lowering CPU utilization. This is a more effective way of sorting and grouping data packets at the NIC instead of the VMM.
Intel VMDQ on Intel® Ethernet controllers can lower CPU utilization and improve LAN throughput by supporting:
• Reduced decisions/data copies by VMM switch
• VM transmit fairness with round-robin servicing
• Operation that is independent from Intel VT-d On the new Intel® 82576 and 82599 10- Gigabit Ethernet controllers, Intel VMDQ provides:
• Flexible bandwidth allocation per VM (only on Intel 82599 Ethernet Controller)
• Hardware support for VM-to-VM loop-back
• Broadcast/multicast replication in hardware
