After a period that felt like pulling teeth, I finally got CUPS 7 to install on VMWare. I got all sorts of crashes and mount problems with even doing an upgrade using ESXi that I decided to use Windows based VMWare. Thankfully it installed, and as a matter of course i used IDE drive mode instead of SCSI. I'd be interested to know if anyone else has had similar problems. The version I was trying to install was 220.127.116.1100-36.
Oh and by the way, I certainly got stuck by this for not RTFM, but just so you know you MUST have CUPS 7, with CUCM 7, otherwise the Sync Agent won't work and you won't get AXL users jumping across the pipe to CUPS.
