Allocating hypervisor resources
In an approach to allocating hypervisor resources for virtual machine deployment, one or more computer processors determine one or more hierarchically grouped computing resources within a hypervisor. The one or more computer processors receive a selection of one or more hierarchically grouped computing resources. The one or more computer processors apply deployment constraints for a workload to the selected one or more hierarchically grouped computing resources. The one or more computer processors determine, based, at least in part, on the deployment constraints for the workload, one or more computing resources from the one or more hierarchically grouped computing resources.
1. A method for allocating hypervisor resources for virtual machine deployment, the method comprising:
determining, by one or more computer processors, an inventory of available computing resources;
determining, by one or more computer processors, a hierarchical model of computing resources from the inventory, wherein the model includes one or more hierarchically grouped computing resources within a hypervisor, the one or more hierarchically grouped computing resources including at least two physical ports associated with one or more system fabrics of physical computing resources, wherein, based on the at least two ports, one or more dependencies between one or more I/O servers and one or more host systems are inferred, and wherein the one or more system fabrics are a network of connected systems that share no physical infrastructure with other fabrics,
wherein determining a hierarchical model of computing resources further includes categorizing the at least two physical ports to indicate the associated one or more system fabrics of physical computing resources and, based on the categorization, defining one or more connectivity groups, wherein a connectivity group is a named grouping of the at least two physical ports;
receiving, by the one or more computer processors, a selection of one or more connectivity groups, based, at least in part, on the categorization of each of the at least two physical ports, wherein the at least two physical ports share connectivity within a virtualized computing environment;
applying, by the one or more computer processors, deployment constraints for a workload to the selected one or more connectivity groups; and
determining, by the one or more computer processors, based, at least in part, on the deployment constraints for the workload, one or more physical computing resources from the one or more connectivity groups, the one or more physical computing resources to be used for a virtual machine deployment.
2. The method of claim 1 , wherein workload deployment constraints include one or more of: a path redundancy, one or more memory resources required for the workload, and one or more CPU resources required for the workload.
3. The method of claim 1 , wherein hierarchically grouped computing resources include one or more of virtual computing resources.
4. The method of claim 1 , further comprising, responsive to determining, based, at least in part, on the deployment constraints of the workload, one or more physical computing resources from the one or more connectivity groups, sending, by the one or more computer processors, information regarding the selected one or more connectivity groups for virtual machine deployment.
5. The method of claim 1 , wherein the one or more system fabrics are comprised of hardware elements including one or more of: a switch, a cable associated with a switch, a router, a cable associated with a router, a gateway, or a cable associated with a gateway.
