Technically you manage any type-1 hypervisor remotely with tools designed for the job. Server Manager in 2012 isn't actually half-bad, but compared to SCVMM (or vCenter in ESX/VMware world), the tools aren't very good. However, the tools built-in with Hyper-V aren't bad, per se, they're just not as good as enterprise management tools go. I would certainly not call Hyper-V's management tools "blowing chunks" by any stretch, but I wouldn't necessarily run Hyper-V in an enterprise without real management tools either - on a Win8 desktop though, they Hyper-V management console is more than enough and competes just fine with tools you'd find in a type-2 virtualization program.
HVVMM is identical to the tools used in 8 (or Blue) because they are literally the same product - Hyper-V Server, on the other hand, uses Windows PowerShell for at-the-server management, and that DOES blow compared simply to Server Manager, which is standard with any GUI install of Server 2008 and later.
Hyper-V's GUI-based management tools (whether you're referring to those in Windows Server 2008 and later, or 8, or Blue) compare quite favorably to those of vmWare Player or Workstation, and are better in some ways, and stomp Oracle VirtualBox quite flat (I HAVE been comparing all three - vmWare and Oracle VB on 8, and Hyper-V on Server 2012). My only quibble is simply the increased HARDWARE requirements to run Hyper-V on 8/Blue compared to Server 2008 and later -and I've stated categorically (in the Microsoft Server forum) that it's a quibble. 8/Blue requires support for EPT/SLAT - because RemoteFX is included with Hyper-V on 8/Blue - on Server 2008 and later, RemoteFX, while supported, is optional; therefore, EPT/SLAT support is also optional. Why is it a quibble, as opposed to a problem? Simple enough - upgrade to ANY four-digit LGA Intel i-series CPU (i3, i5, or i7 in LGA1366/1155/1156/2011) and you also neatly solve the ET/SLAT problem as well with 8/Blue. In THIS thread, I wasn't talking about Hyper-V for enterprise use, but as an alternative to Oracle VirtualBox or even vmWare Player or Workstation, and as Windows VirtualPC's successor, precisely BECAUSE it's a no-cost add-in for Windows 8.
