VMworld: Is it a Scalability Issue to run Drivers in the Hyper-V Parent Partition (Answer: No)
I am sitting in the VMworld session “TA3880 – Head-To-Head Comparison: VMware vSphere and ESX vs. Hyper-V and XenServer”. It is interesting to listen to VMware’s perspective on this. One point that they have raised – which I have heard before – is that VMware ESX has better scalability than Hyper-V because they run their drivers in the hypervisor, while we run our drivers in the parent partition. VMware usually then continues to say that they tried this approach (drivers in the parent partition, or the “service console” to use VMware nomenclature) with older versions of ESX and it caused scalability issues that were resolved by moving the drivers and emulated devices into the hypervisor
