Power on the Virtual Machine and launch the Web or Remote Console. The system will boot into the Cisco Unified OS installation wizard.
Choose the specific compute resource (ESXi Host) to run the virtual machine. Step 3: Select the Deployment Configuration
Typically requires 2 vCPUs, 8GB RAM, and an 80GB virtual disk.
For pre-deployment sizing and documentation, visit the official Cisco Virtualization for CUCM page . This page outlines the required VMware vSphere ESXi versions (typically 7.0 U3 or 8.0 U1 in 2026) and provides links to the specific OVA templates for different deployment sizes (Small, Medium, Large). cisco cucm 14 ova download exclusive

The completion of the OVA deployment merely creates the virtual container. It does not contain the functional bootable operating system or CUCM application software. To complete the installation, you must:
Attempting to install CUCM 14 on a manually created virtual machine without using the official Cisco OVA template will result in an unsupported deployment. The installer detects the virtual hardware parameters. If the hardware signatures (such as specific disk sector sizes, vCPU allocations, and RAM reservation metrics) do not perfectly match Cisco’s specifications, the installation will fail or block future upgrades.
