Abstract:
1. An apparatus comprising: a computer processor and a computer memory coupled to the computer processor, the computer memory having disposed within it computer program instructions that when executed by the computer processor cause the apparatus to carry out the steps of: identifying, by a hypervisor, a guest as a privileged guest from among a plurality of non-privileged guests of the hypervisor based on a time-critical application being executed by the privileged guest; identifying, by the hypervisor, portions of an overcommitted resource that are allocated to the privileged guest, wherein the overcommitted resource comprises at least an assignment of one or more same portions of a resource to the privileged guest and at least another non-privileged guest of a computing device; preventing, by the hypervisor, resource management adjustment to the identified portions of the overcommitted resource that are allocated to the privileged guest, wherein the resource management adjustment comprises an action taken by the hypervisor in response to over utilization of the overcommitted resource and wherein the action includes at least marking as non-swappable memory pages allocated to the identified privileged guest by tracking the memory pages that correspond to the privileged guest and allowing swapping of only one or more memory pages that are not associated with the privileged guest; and wherein preventing resource management adjustment to the identified portions of the overcommitted resource that are allocated to the privileged guest further includes preventing, by the hypervisor, issuance of a memory balloon request to the identified privileged guest.
