CUCM 8.0(2c) on VMWare

After much trial and error, I was able to get CUCM 8.0(2c) installed on VMWare Server. In spite of only being officially supported on ESXi, it is possible to get CUCM 8 running on VMWare Server or Workstation. The best procedure to doing this is:

1. Download OVA file from Cisco and open with Text File to see recommended settings. Some of the hardware specs in the OVA file are required (e.g., dual 80 GB Hard Drives), but others are not strictly checked for during installation, like 2304 MB of RAM (2048 MB worked for me).

2. Configure a new VM with VMWare server using Red Hat Enterprise Linux 4. Any other flavor of Red Hat will not work. The following VM settings worked for me:

  • RHEL 4
  • 1 CPU
  • Dual 80 GB SCSI Hard Drives (0:0 and 0:1)
  • 2048 MB of RAM
  • USB Controller
  • Ethernet Bridged
  • No need to pre-allocate the drives (you can let them grow as needed, though performance will suffer slightly). You can pre-allocate the drives if you want, though. It just takes much longer to set up the VM and takes away a lot of disk space unnecessarily.
You'll then get the Demo license which is good for a single node and 50 DLUs.

  1. You say "You'll then get the Demo license which is good for a single node and 50 DLUs."
    I have been trying to find an official cisco document stating that it is legal to install it like this for demo purposes without licensing. Can you please point me in the right direction?
    Where can I download the install files?
