What is required when deploying co-resident VMs by using Cisco UCM?

A guaranteed bandwidth of 10 Mbps is generally too low for voice and video applications, and specific bandwidth requirements depend on the scale and type of co-resident applications, not a fixed minimum.

While QoS is important, ensuring applications *perform* QoS is not a direct requirement for deploying co-resident VMs; rather, the underlying infrastructure must support QoS for the traffic generated by the applications.

Co-resident VMs, especially with real-time applications like Cisco UCM, require dedicated resources. Hardware oversubscription can lead to resource contention, severely impacting the performance and stability of the Unified Communications services, which is unacceptable for voice and video.

Deploying VMs to a server running Cisco UCM itself is incorrect; Cisco UCM typically runs *as* a VM, and co-resident VMs mean other applications are on the *same physical host* as the UCM VM, not running on the UCM operating system.
