An example system includes a device-specific driver and a pass-through device driver included in a hypervisor. A common host backend is bound to at most one of the device-specific driver and pass-through device driver at a time. The assigned and emulated devices access the common host backend. The system also includes a switch module that sends one or more communications to a guest to cause the guest to switch from using at most one of the assigned device or the emulated device to the other of the at most one of the assigned device or the emulated device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching between devices having a common host backend in a virtualized environment","description":"Systems and methods are disclosed for switching between an assigned device and an emulated device.
