A method of reallocating memory to a hypervisor in a virtualized computing system, includes: assigning priorities to a plurality of logical partitions configured within the virtualized computing system; determining a memory requirement for the hypervisor, the hypervisor configured to manage the plurality of logical partitions; determining minimum levels of memory required for each of the plurality of logical partitions; determining the amount of available memory in the virtualized computing system; and in the event that the amount of available memory is less than the determined memory requirement of the hypervisor, removing portions of memory from one or more of the plurality of logical partitions based on the assigned priorities until the determined memory requirement for the hypervisor is obtained.
