Hyper-V performance tuning – Part 1: Virtual processors - 4sysops
Good article on Hyper-V Virtual Processors
Not sure how virtual processors work with Hyper-v so need a bit of advice please
Server 2012 with 2 x E5-2620 cpu's.
Task manager shows 12 cores and 24 logical processors. When setting up the virtual machines how many virtual processors have I got to play with? Is it 12 or 24? I understand I need to keep some cpu's back for the host.

Thanks. So going by that I can use 11 cores in the VM's and 1 for the host.
Using PowerShell to find the virtual processor to logical processor ratio of Hyper-V - Ben Armstrong - Site Home - MSDN Blogs - you will find the same page linked from VeryPC_Ed's reply above. You can run to a multiple of 8 (under 2008 R2) but that is the maximum you should do.

Beautiful post and recommendations. Thanks! I'm a new 2012 HyperV admin and the rule of thumb is good - though I feel like I'll max out my available RAM long before maxing out my processor count!
