Vista - hyper-v and cpu

07-17-2009

Hello. I would like to ask about Win2008 and Hyper-V.
Suppose i have a machine with 2 Xeon Quad core cpu's and all the memory and
hdd's i want. Operating system is Win2008 Datacenter Edition.

How many virtual machines is suggested to install regarging cpu resources? I
realize that if i i install a demanding virtual machine like SQL, will have
to assign more cpu resources. But suppose that i am refering to low demands
applications. Is there a general guide? For example vmware suggests 2
virtual machines per cpu, 4 in dual cpu machine.

Thanks, Peter

Hi Peter,
Hyper-V uses hardware based virtualization; the CPU performance compared to
VMware is in another class.
It is generally not going to be the bottleneck.
Hard drive speed and RAM are the main concerns.
Build a test rig and have a play, you will be impressed.
Sincerely Steve.

Hello Steve, thanks for replying. But you confused me a bit :-)
What do you mean by "Hyper-V uses hardware based virtualization; the CPU
performance compared to
VMware is in another class"
I am new to virtualization, sorry if i can't follow you completely

Ok, I will use 15K SAS drives and lot's of RAM. But how many virtual
machines can i assign per core in general?
Regards,Peter

The new 64bit CPUs have virtualization functionality built into the chips
(you can think of this as akin to hardware graphics aceration in video
cards.)
Hyper-V will only run on CPUs that support hardware virtualization.
As I said before, if you are not using CPU intensive applications then you
can put 10 or 20 onto a core really.
Otherwise it's "how long is a piece of string" if you get my drift.
