I wanted to get any feedback with installing Microsoft System Center Virtual Machine Manager on our Hyper-V host that also has Symantec Backup Exec 2010.

Our host is running as a member of the domain, and has Backup Exec 2010 installed. We would like to add Virtual Machine Manager 2008 to manage our vm's. I know Microsoft recommends that not much of anything be running on the host, but I wanted to see if anyone is running this configuration and any potential problems/issues I should be looking for?

Also, can we use the workgroup edition of SCVMM or do we require the Enterprise edition? 

Thanks,
