Everyone hates change
I was concerned at first about VMware's changes in licensing but after reading the full details, I realize it’s not a big deal. The vRAM limitation only applies to Essentials and Essentials Plus licenses. Physical RAM is not limited, only the amount of RAM actually allocated to powered on VMs.
All the strum und drung about converting to HyperV is hot air. HyperV simply is not competitive at the enterprise level. Best reason to use Hyper V is that one gets to run 4 Server 2008 VMs with no additional licenses. That makes it very attractive to SMBs but HyperV has none of the enterprise class features of VMware vSphere.
Further, with vendors prepared to come out with tera-scale processors supporting hundreds of cores per processor, the removal of the CPU core limits is pretty attractive.
A two node, 4 processor system using Enterprise licenses will, by default, be entitled to 4 physical processors and 128GB of allocated virtual machine RAM which seems in line with reasonable CPU->RAM ratios (that’s 64 2GB VMs or 32 4GB VMs which is a lot to expect of two nodes with two CPUs each). So, in all, this is much ado about nothing in the end. People will complain and then they will pay. Some of the smaller shops may transition to other platforms but the midsize to enterprise customers will simply adapt.
