Best Practices - DC in Hyper-V Environment.

How does one live with the risks of a PDC as a VM with the host on reboots? Do you leave the host off domain?
Yes, the host should not be on the domain unless you feel that the high availability of your AD infrastructure is so extreme that you don't care about it coming up. If you had VMware, XenServer or KVM you would never even think of putting them on the domain (literally, the idea would never occur to you) so why do it with HyperV?

Inherited an environment here with the PDC (2008R2) on bare metal, dishing out VM's.
I have some concerns with this setup, is this normal? How does one live with the risks of a PDC as a VM with the host on reboots? Do you leave the host off domain?
I do the DC's (including the one with the PDC emulator) as VM's. I don't usually put the VM host in the domain but, with hyper-v you pretty much have to. If you have more than none host and DC's and each host it's not a big deal. if you only have one host you really need to look into putting a second DC somewhere even if it's physical.
We run our DCs on Azure. Eliminates the concern entirely.

Thank you both!!! That was my suspicion. We are no where remotely close to HA, I'll plan the upgrade to 2012 to move to the hypervisor off domain.
So used to VMWare that the whole hyper-v thing occasionally screws with my brain.

Just wondering... Why would you use Hyper-V over ESXI or the like?
-
@Hubtech I personally wouldn't, but one plays the hand one is dealt.

Cost. I think you need System Center for it's Vmotion like feature. But VM Backups/snapshots are supported at the host level with the free version. Personally I think vmware is worth the money.

@thecreativeone91 @Hubtech
Yes, to elaborate, $$$$$$
MS almost gives away their stuff to non-profits and thus... hyper-v everything.
Example: we just bought a license for 2012 datacenter, it was something silly like $50

And Hyper-v baremetal is free.

If you are looking at cost, why not look at XenServer? It has all the enterprise capabilities for free in an easy to use package. Full disclosure, I deployed a Hyper-V infrastructure.

So is ESXi.

@coliver I have a say in what we use daily, but not the final one. Also has to be something the team is familiar with. They've been around longer than I and they've fought more with hyper-v than any of the alternatives.
Again if it was up to me, VMWare.

HyperV gives you backup API for free, pretty significant. Add in Unitrends or Veeam and you've got a massive free solution. And while StarWind two node HA is available free for both, it is better integrated with HyperV. At one or two nodes, HyperV has become very hard to beat because of its ecosystem.

ESXi isn't free with all feature. ESXi does have a free version but the essentials license are $560/year if you want updates which is for three servers (with a max of 2 cpu's per server).

All HyperV is bare metal. It's a type 1 hypervisor. There is no way to use it any other way.

I got you @MattSpeller no need to rock the boat

Hyper-V isn't free for all features either. To get some of the more advanced stuff you need SCVMM. Not that the majority of SMBs actually need the advanced stuff to begin with.

It's easier too. Downsides to XenServer is the lack of free backup options for small scale and lack of simple replicated local storage. You can do it, but it is more complicated (by quite a bit.) But overall, XenServer is my favourite.

Yes but it's inside the OS we well. They call it Server 2008/2012 with Hyper-v or Hyper-v 2008/2012 Server.

All four bare metal hypervisors have a free version: HyperV, VMware ESXi, Xen / XenServer and KVM.

HyperV isn't free with all the features either. But with more than ESXi. I think blocking the backup API was SO foolish on VMware's part. It made their free version never make sense. Either XenServer or HyperV is always a better choice.
