By default, when virtual machine is created on Hyper-V host, its clock is "bound" to the virtualization host operating system clock via Hyper-V integration services. If there are two or more virtualization hosts in the same network, it may happen the operating system time on one of the hosts to be different comparing to another host.
Sometime, sysprep operation may fail with the following error message:

Just finished some quick but rather indicative tests of VMware vSphere with View 5 and MS Windows 2008 R2 SP1 Hyper-V
We are long time looking for virtualization platform that would allow decent quality of 3D graphics and modeling applications.
To install a new KMS host key for Windows 8 activation or for Windows Server 2012 activation, run the following command:
cscript %windir%\system32\slmgr.vbs /ipkNote In this command, "KMS host key" is a placeholder for the new KMS host key for Windows 8 activation or for Windows Server 2012 activation.
Important: Every KMS host key is associated with a group of Windows editions.
To enable or to disable hyper-threading on virtualization hosts?
There are many articles, documents and discussions in Internet and there is no definitive answer about the hyper-threading usage in virtualized environment.
A processor architecture feature that allows a single processor to execute multiple independent threads simultaneously.
Quick check list and brief instructions on hyper-V RemoteFX set up
- Processors must support Second-Level Address Translation (SLAT). Intel-based processors, Extended Page Tables (EPT) == SLAT. AMD-based processors, Nested Page Tables (NPT) == SLAT.
The Old Story
Every year purchase new server(s) loaded with as many disk as it can handle. Install software and transfer data from the old servers (3-4 years old) that go out of business due to reliability consideration and increased need of storage space.

Virtualization and CAD software (AutoCAD and similar) at the end of year 2012.
Recently tested XenApp, XenDesktop and Server 2012 with Hyper-V + Nvidia Quadro 4000 and Windows 8 virtual machines.
XenApp is OK with AutoCAD. However AutoCAD LT is not compatible with XenApp - limited to 2 Acad instances only.
