The overhead of a hypervisor shouldn't even be a consideration. There is literally 0 benefit to doing this. You could use a hypervisor and have a true HA setup so if a node takes a nose dive, everything is instantly (I mean instantly) up on another node.
You wouldn't even have time to blink.
Can you walk me through how you're envisioning that working? I can't reconcile it to the description of the set up for this project. I presume you're talking about setting up Hyper V replicas or something, but because I'm dealing w/ two production boxes that are already actively sharing the workload the failover wouldn't be any different from the user's perspective, and will require the same replacement of the failed drive with or without virtualization.
No, Hyper-V replicas are not viable for high availability. They don't sync between the nodes in real time. You need HA storage like Starwind VSAN to do that.

KVM, XenServer, Hyper-V and ESXi all have the capability to move VM's around from a failed/failing host without you even having time to read the email.
These are all installed to bare metal, and thus are leveraging the tools you have in place now, but don't require you to manage them.

Prepare for the wrath of the Mango!
As I said - prepare for the wrath of the Mango.
I have to get on the road, I'm sure this thread will have 300+ posts on it by the time I'm back online.

@dashrender "Easier backups", how so? Seems less-easy.
Can't be less easy. Can be the same or easier. You lose nothing, only gain options.
Less easy because without virtualization all I have to back up are a folder of images and a small handful of MySQL data files. Adding virtualization for the benefits I perceive peeps here to be championing would require backing up the entire VMs, which is less easy not to mention a much much bigger backup footprint, no? What am I missing?

The high availability at the hypervisor level is a minor point. It might be useful for the non-database workloads, but the database replication at the application layer is better if he's going to go that route as it protects against more.

Can't be less easy. Not possible. Literally, it's impossible to be less easy. Because ANY option you have with physical you retain with virtual, but with virtual you have more.

As an example you could use XO's continuous replication capability and have the system configured that if Host 1 goes down to instantly power on the VM on your other active host.
Literally nothing you have to do but restore host 1.

The reasons for virtualization are...
- adds lots of benefits that you may or may not use, that you might need them in the future and can never tell today is a huge piece
The reasons not to virtualize are...
none really. That's why we always virtualize.

@jaredbusch For Server 2016 right? Saw that, pretty annoying. But I like the idea of breaking things up into containers eventually so I may bite the bullet. At the moment I have 1 2012 R2 license which I think works for the decacore server w/ no extra licensing.
THat's correct.
No, that is not correct.
@creayt a single license covers dual 8 core processors. You will need two more 2 core pack licenses for the decacore box.

What he means is that you can still choose to only back the exact same files you are backing up today.
But, with virtualization, you can more easily backup the entire VM if you want to. Also, you can move to new hardware simply by copying the VM to new hardware, instead of reinstalling it (or imaging it then installing new drivers, etc). -

There is no 2 core pack for 2012 R2.

By less easy I just mean less work, less things to back up. I'd still need to back up the same things with virtualization that I will without, but with virtualization there are additional things to back up is all I mean. Easy was a poor choice of words, sorry.

He cannot buy 2012 R2 anymore. You can only buy 2016. He can install 2012 R2 as that is perfectly allowed, but he has to buy and appropriately license 2016.

What extra things do you think you need to backup with virtualization?

That's what I was saying. That's only true for 2016. On 2012 it's per-processor, not per core.

But you could opt to only backup the database files and not the entire machine it's self. That option still exists. And doesn't go away.
You simply have more options to restore in the event of a failure.
