An example method of migrating a virtual machine includes transmitting, from a hypervisor, a migration indicator to a guest. The hypervisor receives a free memory page indicator from the guest that identifies one or one or more free memory pages corresponding to a virtual machine. The hypervisor then places the virtual machine in a suspended state. While the virtual machine is in the suspended state, the hypervisor modifies a dirty status and a migration status corresponding to one or more dirty memory pages. After resuming operation of the virtual machine from the suspended state, the hypervisor modifies a migration status corresponding to the one or more free memory pages to exclude the one or more free memory pages from a migration. The hypervisor migrates the one or more dirty memory pages."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Virtual machine migration acceleration with page state indicators","description":"Methods, systems, and computer program products are included for migrating a virtual machine.
