Is there any plans to support CUEAC with VMware ESXI 4.1? If yes any roadmap when this will be available?
CUEAC is currently supported by VMWare ESXi 4.1:
Cisco Unified Attendant Console server is supported in a production environment on VMware ESXi 4.0 or 4.1 running on a host machine that is compliant with Cisco's Specifications-Based Hardware Support program. For more information about this program, please visit: http://docwiki.cisco.com/wiki/Specification-Based_Hardware_Support.
Note: This feature is supported only with Cisco Unified Communications Manager 8.0(1) and later.
Most products are slated for end of June time frame. CUCM is slated June 28th. All products may not release exactly on the same date so plan for something in that time frame
