Prioritizing scheduling of virtual machines by recalculating priority numbers for each virtual machine based on the interaction of users with the virtual machines
Abstract:
A mechanism for prioritized scheduling of virtual machines is disclosed. A method includes receiving control of a virtual machine (VM) managed by a virtual machine monitor (VMM) on a host machine and executing a prioritization task involving a hardware emulation of the VM, determining an interactivity statistic for the VM based on a hardware type factor of the hardware emulation of the VM, calculating an interactivity rate for the VM based on the determined interactivity statistic for the VM, sending the calculated interactivity rate to a management daemon if the calculated interactivity rate is different than a previous interactivity rate for the VM, re-calculating priority numbers for each of the VM and all other VMs managed by the VMM based on the calculated interactivity rate, and providing the re-calculated priority numbers to a scheduling algorithm of a scheduler of the host machine for the scheduler to utilize in prioritizing the VM process.
