This issue has been solved. See solution.


We would ilke to install Endpoint Protection AV and we would ilke to know if it is a good point to install this software on a Hyper-V virtual machine rather than a physical machine (Best practice).

Thanks for your help

You would want to install the antivirus protection to all machines virtual and physical. I run hyper-v and my host os is protected along with all clients since you cannot scan the virtual hard drives with the host scanner

Thanks for your answer.
I don't understand exactly your point with the virtual HD scan.
Do you mean that :
- Host scanner won't scan Hyper-V virtual machine HD
- You need to install a Sym AV client on each Hyper-V virtual machine for their HD to be scanned

- Host scanner won't scan Hyper-V virtual machine HD

You have to create a scanning exclusion for this.Other wise it will cause performance issues

- You need to install a Sym AV client on each Hyper-V virtual machine for their HD to be scanned

Yes you have to do this..

Please don't forget to mark your thread solved with whatever answer helped you : ) Thanks & Regards Aravind

If you have an infrastructure in my opnion  it is better to install on a Physical machine

I assume you're talking the SEP Management server as a VM.   We tried that, but as the number of clients grew so did the demands on the VM.  We were up around 3000 clients and even with the SQL database on a seperate server the demands became too great with CPU utilization constantly up around 80% and sometimes hanging at 100% for an extended time.  We had to move it off to a physical box.   We are now up around 6000 clients and it is running much better with CPU utilization averaging 40%.  We did have one spike in the last 30 days that took it to 80%. 

So, for a small shop a VM would work well.  I'd recommend that if you are going to have the database on the same host that you provide lots of resources.   You might also consider bringing up a second SEPM server on a different VM host so you can to load balance or at the very least have it act as a fail over.

We have over 40,000 clients and run our SEPM servers on virtual machines. Perhaps the key is we have 3 load balanced SEPM servers. IMHO, it's cheaper to light up two or three VMs -- on Hyper-V hosts that can run up to 8 virtual machines each -- than it is to purchase and devote an entire physical server to the task.
