*URGENT* Maximum virtual Processor

Hi!
I have a proliant ML350 G6 with 2 XEON processors with 8 cores each. In
hyper V i can just assign 4 logical processor and this indicates 24 procent
of total CPU power. For this machine i need to use more. Is this possible?

I use Hyper V R2 standard.

Otherwise I need to run a Remote desktop services server on the host and
then virtual machines on this config, does that work?

Regards
Jimmy

No, it isn't possible to assign more than 4 virtual CPUs to a guest OS.
However, with that configuration, I'd turn off hyper-threading so that you
only have 8 total cores. Now, when you assign 4 virtual CPUs you'll have 50%
utilization on that VM. (Assuming you haven't over-committed.)

Can you run RD Session Host on the physical host? Yes, but it's not
recommended. And it will affect your licensing, since running any additional
roles on the host eliminates your +1 license.

Hi!

Thanks for the answer! Isnt this limitation a problem for bigger companies
with only 4 cores availble in Hyper V?

Wonder what good hyperthreading is good for if you just can turn it off?

I have already installed the rd host on the physical machine and also the
Hyper V role. I moved the other servers and virtualized them. I disable the
domain windows firewall to make them speak to each other.

Can I ask you what backup solution you prefer? I have 2 server one with this
RD host and Hyper V with 2 servers. I also have physical server with SBS.

Best regards
Jimmy

What are you planning to run in a vm that needs more than 4 processors?
Maybe it isn't a good candidate for virtualization.
