By pinning your CPU's does this cause a problem with VMotion?

You do want to tweak your McAfee settings as much as possible. Especially
if you are using PVS.
The other thing we are finding is we are getting better performance by
pinning VMs to CPUs. Not sure if this is a NUMA issue or a problem with the
scheduler.

We've set up all VMs with 2 CPUs and 4GB RAM. We are not overcommitting our
CPU cores.
However, we still get 100% CPU for extended periods of time.
Internet Explorer 8 seems to be using most of that CPU. MacAfee AV also
seems to be going up and down on CPU usage.
Any clues?

PAE actually makes term server run poorly with most application sets. I
would definitely recommend disabling it.

Best 32 bit/W2K3R2 setup I have found is 2vCPU/4GB RAM for each VM. Make
sure you don't overuse cores. there shouldn't be anymore vCPU's than cores
on your physical server. Memory shouldn't be overcommitted either (I reserve
2GB RAM for XenServer). On a 24GB Dual Quad (not Nehalem) blade I
comfortably get (4) Citrix server VM's with the config above.

Getting a 3-1 consolidation of this config. Our apps are memory starved and
not CPU.

Hi all, does anyone have any guidelines for Citrix VM servers on ESX 4.0?
I currently have 5 Windows 2003 R2 PS 4.5 servers on ESX 4.0. They are
assigned 1 virtual CPU and 2GB of Memory.
They're all spiking up to 100%CPU for extended periods of time with about 15
users each. Should I have 2 CPUs or 4?
Any other advice would help.
Thanks,
