Hi Bagnolini,
Sadly, that is not supported
Cisco is introducing software application versions from the Cisco® Unified Communications portfolio (Versions 8.0(2) and later) that are supported for production use on specific configurations of VMware vSphere 4 (ESXi 4.0), specific Cisco Unified Computing System™ (UCS) servers, and specific storage configurations.
• Cisco UCS B200 M2 and UCS B200 M1 Blade Servers with third-party Fibre Channel storage area network (SAN)-attached disk arrays are supported.
• Cisco UCS C210 M2 and C210 M1 General-Purpose Rack-Mount Servers with specific configurations of either direct attached storage (DAS) or Fibre Channel SAN are supported.
• Cisco UCS C200 M2 General-Purpose Rack-Mount Server with specific configurations of DAS is supported.
• VMware ESXi 4.0 is required for all of these servers. Available applications include IP telephony, emergency services, messaging, presence, customer care, and management; refer to http://www.cisco.com/go/uc-virtualized for details. Application co-residency is also supported; refer to http://www.cisco.com/go/uc-virtualized for details.
Cisco Unified Communications applications require use of VMware vSphere 4 (ESXi 4.0) to support Cisco Unified Computing System hardware. No applications run or install directly on the server hardware; all applications run only as VMware virtual machines. Cisco Unified Communications does not support a physical, bare-metal, or nonvirtualized installation on this server hardware.
