For those of you wanting to run Cisco Unified Communications Manager Business Edition (CUCMBE) on VMware for lab purposes. You’ll need this tip. As a reminder, VMware is not yet officially supported in production environments.

First of all, you need VMware ESXi 4.0. When you configure your virtual machine settings select Redhat Enterprise 4, 2vCPU, 6GB memory and 250GB drive. When you boot the VM from the CUCMBE ISO, you will then be allowed to install Cisco Unified Communications Manager Business Edition.

If you use the shipping (FCS) version of 7.1.2 or below, VMware works fine with 80GB HDD, 2GB RAM, 1vCPU.
