Abstract
Systems and methods are disclosed for assigning an I/O resource to a virtual PCI device. An example system includes an I/O resource table that stores a pool of one or more available I/O resources for assignment to one or more virtual PCI devices. The system also includes a hypervisor that maintains the pool of I/O resources, assigns one or more I/O resources from the pool to a virtual PCI device, and notifies a guest running on a virtual machine that the one or more I/O resources is assigned to the virtual PCI device. The hypervisor and virtual machine are executable on a host, and the virtual PCI device is exposed to the guest.
