In one embodiment, a computer system includes at least a first device and a second device that function as a backend device. The first device is currently used by a guest of the computer system as the backend device. A hypervisor of the computer system receives an indication from the guest to use a feature of the backend device. The hypervisor determines whether the use of the feature of the backend device triggers a switching condition. In response to a determination that the switching condition is triggered, the guest is switched to use the second device as the backend device. The switching operation can be transparent to the guest."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Feature driven backend switching","description":"A method and system for switching backend devices in a virtual machine system based on features of the backend devices.
