After Complaints, VMware Revises VSphere 5 Licensing

...I still think this was nothing more than a cash grab by their corporate parent, EMC.
As if mugging you for all your lunch money at disk-adding time wasn't enough for EMC, right?
The "Civilized World" jumped the shark ca. 1973.
I hate to say it but EMC has finally influenced VMware.
Of course the new licensing model doesn't limit CPU. That is because there are VERY FEW VMware deployment that max CPU. RAM is usually the cap. But trying license based on physical RAM would be too easy for them. Let's license on what everyone uses most. Virtual (non existant) RAM. I know in my environment everyone that wants a server says they need XX GB of RAM and they use about 1/4 of the RAM they request. So rather than argue with them, I give their server the XXGB of RAM knowing that I can over subscribe the RAM. This is the greatness of VMware. Effeciency.
So now they are going to license us on the one thing that we don't really use. We aren't licenced on what we own or what we use but what we "MIGHT" use. Ridiculous scheme trying to squeeze every dollar out of their market share. This is what EMC does. To get any real funtionality out of their products you have to license more and more features that are already right there in the product. And we see how well that has worked for them. They are bleeding customers. VMware really doesn't have any competitors right now. If they keep this model, they will.
No, but you could look a Citrix XenServer. They are behind on features, however they license per SERVER. Unlimited cpus, unlimited cores, unlimited RAM. From a technical implementation perspective, they are second to VMware. Hyper-V is third technically, but of course will likely surpass XenServer in a year or two due to Microsoft's continued heavy investment.
I never used one of the commercial products for virtualization. We were constrained to $0 for the software budget for virtualization, so we toyed with VirtualBox and KVM on Linux. Our development machine was not on a UPS, and over the course of a few weeks we had the occasional 20 second power outage in the building. Some of our VirtualBox images were corrupted by the outage, the KVM images were not, and that was enough to put us onto KVM for production (even though our production servers are of course on UPS with a backup generator). It's possible whatever problem we had with VirtualBox has been fixed in more recent versions or that we misconfigured the storage settings, I don't know. But KVM was more reliable without any tweaking right out of the box, so we went with that.
KVM supports live migration and live storage migration, although we have not used either feature. The virt-manager GUI you can use with KVM is easy enough - create, clone, start, stop, change settings, and view and interact with the virtual machines all with clicks in the GUI. I'm sure VMWare has earned its impressive reputation, but free is always nice. Good luck.
(Disclaimer, though I don't work for the mentioned company, I do stand to benefit for business they conduct)
So, the *storage migration* feature (where backing store changes with nothing else changing) is not currently implemented as far as I know by anything other than VMware in x86 world (though perhaps the building blocks are there now in one way another). Other than that (live migration, DRS but with more flexible criteria, HA VM restart, and failure avoidance), Adaptive computing has an offering built on KVM. http://www.adaptivecomputing.com/products/moab-adaptive-computing-suite.php Their product pages are fairly vague and hard to get a feel for it (mainly because virtualization is a relatively small subset of the product), you kind of need a demo to get a whole picture. This is probably the most polished offering I've seen with my own eyes and touched with my own hands. They actually have quite a few customers using vCenter under the covers because they did some stuff above and beyond VMware with VMware's own products, and have all of it working for VMware and KVM except storage migration which is limited to VMware at the moment.
IBM also has at least two products with GUI, VMcontrol I've never used and LoadLeveller is starting to accept KVM VMs as workloads IIRC. IBM will also bundle the aforementioned Adaptive product bundled with hardware if you like.
I've heard some talk about OpenStack, but never seen it in action so I can't speak for or against it other than to say their goal ostensibly lies in this direction.
I've seen marketing material for RHEV-M which suggests a vCenter-like set of capabilities, but no hands on to *really* vouch for or against it. T
In general, the biggest thing to prepare yourself at the low level is a drop in I/O performance. virtio-blk and virtio-net mitigate it pretty well, but if you like using e1000 because you don't have to sweat Windows drivers in guests, the performance will be on the floor relative to VMware, for example (and KVM maintainers know and don't care).
XML is like violence. If it doesn't solve the problem, use more.
Keep in mind that increasingly, VMware is seeing the individual hypervisors as little more than an means to the end of selling their higher-order management software (vCenter and such). I would not be surprised if one day vCenter ends up managing Xen and/or KVM the same way it will manage ESXi.

If you are virtualizing Windows only, Hyper-V is probably the best bet. Completely supported by Microsoft for low low cost of nothing. Supports Live Migration, Dynamic Memory (servers only start with X but can request up to Y if needed) and has very usable GUI and yes, it's true HyperVisor just like ESXi or Xen.
It's worse than you say.
It's not RAM they are licensing to you, it's vRAM, which means memory that you've allocated to the VM's, but may not be using. vRAM is calculated by summing up the allocated memory of each virtual machine. Which is to say, after spending years saying, "but our product is better than our competitors, because you can oversubscribe your memory," they have now said "gotcha!". This move was A) evil, as they told customers with fully paid up maintenance contracts "no, we won't honor the contract, you'll have to buy more product," and B) stupid, as the licensing model directly undermines one of VMware's principal advantages.

Red Hat is rewriting RHEV to be all open source and will no longer require Windows. I work with it for close to a year.

It seems many of you don't know (as did I until not so long ago) that Parallels, the virtualization folks of Mac fame, also do "Parallels Bare Metal" which is essentially a direct attack on VMWare's lunch money.
The Parallels Bare Metal 4 is near VMWare ESX 2.x functionality or so but the new Parallels Bare Metal 5 (which is now in beta) has pretty much most of the VMWare 3.x-4.x ESX/vSphere series features. Although it is much more command-line centric - which is good for some of us - and the procedures for converting physical and virtual machines from other vendors are quite different - which you simply have to learn and get used to (yes you can convert ESX/vSphere crap on-disk and via Parallels "importer" in-guest agent).
The thing comes with Windows, OSX and Linux management consoles ala the VMWare editions of old.
So for all of you out there who need to appease corporate demons with a commercial product with proper support arrangements etc, take a look.
I was quite pleasantly surprised and I am holding back any moves to vSphere 5 for many of my clients with the aim of deploying Parallels instead.
Oh and pricing: $499 per-host (no idiotic per-core or per-ram or per-disk nonsense here) for "Small Business" (which has everything you need really, even for big shops since you can script everything using their command line tools) or $999 for their "Standard" which comes with a wacky centralized automation/web-interface/event-ticket/delegation/who-knows-what-else management gizmo.
See those numbers and weep, oh vSphere 5 victims!
They also have a "Virtuozo" product that seems aimed at the VPS rental market.
