Hi Guys.
Any idea what percentage of hyper-v deployments in the real world are running on core and how many are running in the ful GUI version of windows?
Cheers

| You'll have to ask Aidan Finn about that... he and some other MVP's do the annual Hyper-V survey and that's one of the questions in there ;-) |
Greetsz,
Jeff. |

12.99% use Core and the rest use the GUI. Reason: it's very difficult to troubleshoot a machine with no GUI. I am still dubious about the new model where you can flip between Core and GUI. Haven't tested yet, but I'm GUI first all the way. I don't surf on my hosts, the Windows Firewall is up, patching/rebooting isn't an issue with clusters (esp. now with WS2012 Cluster Aware Updating), and I would limit who is an admin on the host. Saved diskspace .. pah! Try buy a server disk of less than 300 GB and see how long it takes to be delivered. Saved RAM ... a few MB, no more.
We asked around on the forum a few years ago, and there was almost universal dislike of Core because of the trouble with troubleshooting. |

Cheers guys,
Is there a link where we can see the results of the last survey? |

> 12.99% use Core and the rest use the GUI
I looked up your report :-)
You left out Hyper-V server, which counts as Core from a managebility perspective. Hyper-V server is 16%, which leaves 71% for the full GUI server. Still a good majority, but not as dramatic as 87%.
That was last year, by the way. Curious about the trend in 2012. Is that survey online? Can't find it right away.

| I have a feeling the number might go up a bit with 2012, with some of the enhancements - especially native nic teaming. 3rd party nic teaming and nic configuration in general under 08r2 was impossible without a gui. |

I also think the number of those going core only might go up with all the new PowerShell stuff in 2012.

Uh not really James. Some of the most basic stuff requires a gui, most common are configuring network and storage adapters
When the vendors add management through wmi, command prompt or powershell cmdlets then the gui is not needed any more. |

Both Intel and Broadcom can have teaming configured through the command line.
Plus with WS 2012 it's all native anyway. |

So there is a negligeable difference in performance between running the Hyper-V role on Full or Core?
But what about Full and Hyper-V Server 2012?
Now I'm looking at this from the perspective of someone who works with servers that have 2GB to 8GB of RAM (even my newest laptop has more!).
I'm thinking that the underlying OS (Full install) running the Hyper-V role is going to "eat up" 1 GB or RAM right there.
ESXi 4.x is something like 32 MB.
On the other hand, if you have a server with 64 GB of RAM...
Maybe the 1 GB consumed by the Full install doesn't make that much of a difference.
Is that the way people must be looking at this? People = the 70% of Hyper-V users that are running Hyper-V in a Full Windows Server install. |

Best practice is to reserve 2gb on the host. I'm sure hyper-v server requires far less, a la esx. Ive never used it myself.
I have a variety of hosts and many with only 8-16gb of ram as well as clustered hosts with 10x that. The 2gb means little at that point and a machine with 8gb is only intended to host a couple vms anyway... |

My recommendations on GUI vs Core vs Minimal on WS2012 don't change. Not everyone agrees with me, but I prefer simplicity when things go wrong. Still the vast majority of people go for a full install.
Do not use the root memory reserve setting in WS2012 unless instructed to do so by MSFT Support. |

Used to go for Core. Not for resource use, but there's far less updates.
I do not believe such is the case with Windows Server 2012.
Go for GUI |
