A method for allocating virtual machines (VMs) to run within a non-uniform memory access (NUMA) system includes a first processing node and a second processing node. A request is received at the first processing node for additional capacity for at least one of (a) establishing an additional VM and (b) increasing processing resources to an existing VM on the first processing node. In response to receiving the request, a migration manager identifies whether the first processing node has the additional capacity requested. In response to identifying that the first processing node does not have the additional capacity requested, at least one VM is selected from an ordered array of the multiple VMs executing on the first processing node. The selected VM has low processor and memory usage relative to the other VMs. The selected VM is migrated from the first processing node to the second processing node for execution.

Method of migrating virtual machines between non-uniform memory access nodes within an information handling system

In accordance with these and other embodiments of the present disclosure, a system may include a processor and a hypervisor comprising a program of executable instructions embodied in non-transitory computer-readable media accessible to the processor. The hypervisor may be configured to, when read and executed by the processor: instantiate one or more virtual machines to execute on the hypervisor; maintain a virtual machine dependency map having one or more entries, each entry setting forth a target virtual machine and one or more virtual machines to which the target virtual machine is dependent; and determine whether to power on a target virtual machine based on information set forth in the virtual machine dependency map.

Systems and methods for defining virtual machine dependency mapping

In one embodiment, a system includes a device and first and second processors. The first and second processors are configured to access first information. The first information includes a first parameter and a second parameter. The first parameter is associated with a position of the device relative to the first processor. The second parameter is associated with a position of the device relative to the second processor. The system is configured to access second information associated with a virtual machine. The virtual machine is configured to run on a host operating system. The virtual machine includes a guest operating system configured to communicate with the device. The system is also configured to automatically select the first processor based at least on the first information and the second information and to associate the virtual machine with the first processor in response to automatically selecting the first processor.
