I've searched and cannot find documentation on maximum vCPUs, RAM and disk can be allowcated to a VM on Acropolis. Also looking to see if there is a limitation to how many VMs can run on one host. Can someone point me in the right direction?

Acropolis 4.6 System Maximums:

4.5 (might be the same)

https://portal.nutanix.com/#/page/docs/details?targetId=Web_Console_Guide-Acr_v4_5:app_system_maximums_r.html

Also from the AHV release notes:
https://portal.nutanix.com/#/page/docs/details?targetId=Release_Notes-AHV_20160217:Release_Notes-AHV_20160217

Important: As of NOS 4.1.1 and Acropolis base software 4.5, any VM with a vCPU setting that is greater than the actual physical number of CPU cores on the underlying host will not start. This condition also applies to existing VMs from the NOS version from which you are upgrading. To start these VMs, reduce the vCPU count to a value equal to or less than the number of actual physical cores.
