Although the requirements for the Kasm services a quite modest, provisioning each end-user Kasms requires additional compute resources as specified in the Image configuration. The default Kasm Images are configured to require 1768MB of memory and 1 core. Kasms will not be provisioned if the minimum resources requirements on the Agent are not met.
