Recently Microsoft delivered the Hyper-V release candidate (RC).

Hyper-V RC has three main enhancements from the beta release:

<ul><li>An expanded list of tested and qualified guest operating systems including: Windows Server 2003 SP2, Novell SUSE Linux Enterprise Server 10 SP1, Windows Vista SP1, and Windows XP SP3.
</li>
<li>Host server and language support has been expanded to include the 64-bit (x64) versions of Windows Server 2008 Standard, Enterprise, and Datacenter - with English, partial German, and partial Japanese language options now available and the ability to enable the English version of Hyper-V on other locales.
</li>
<li>Improved performance & stability for scalability and throughput workloads.</li></ul>
Now a few screendumps:
Fedore Core 8:


What i particularly like very much, is the ability to keep 1 VM from taking all available CPU:



Power usage of the current hardware: 65-70W.
I will change the videocard to get some reduction on that, but also add some more drives and an extra NIC. So usage will get a bit higher by that.

Getting your physical machines virtual is not an easy job BTW, for as far as i can tell (the host is only 24 hours young). Nevertheless, i really like what i see so far.

Futures are rich
Hope this will trigger Vmware to put more in the Vmware server
is there any build in remote console via web?

I haven't seen anything for remote console via web yet. But i'm just a beginner with Hyper-V, so who knows...

What i did found out and what is a disadvantage: when you RDP to the host, the mouse doesn't work in the connection (that's the MS name for a VMWare console screen) with a VM. So you have to control your VM with your keyboard[:(] Maybe VNC-like things will help in that.

Looks very similar to what IBM is doing since the introduction of the POWER5 processor: Micropartitioning.

Does W2K8 also offer the option of 'borrowing' un-used CPU-cycles from a VM-machine that currently is not using its maximum amount of CPU cycles?

If you mean borrowing cycles from another CPU, no, AFAIK. A Virtual Machine is bound to a fixed number of processors.
