A mechanism for load balancing in a memory-constrained virtualization system is disclosed. A method of embodiments of the invention includes determining that one or more collected metrics have triggered a load balancing operation of a host controller machine, wherein the one or more collected metrics include memory-related metrics of one or more host machines managed by the host controller machine and of an overall system of the host controller machine. The method further includes selecting a host machine of the one or more host machines to migrate a virtual machine (VM) from as part of the load balancing operation and selecting a VM of a plurality of VMs hosted by the selected host machine to load balance migrate from the selected host machine, wherein the selecting the host machine and the selecting of the VM includes consideration of the memory-related metrics of the host machine and the VM.
