Abstract

Examples include a method of performing failover of in an I/O architecture by allocating a first set of resources, associated with a first port of a physical device, to a virtual device, allocating a second set of resources, associated with a second port of the physical device, to the virtual device, assigning the virtual device to a virtual machine, activating the first set of resources, and transferring data between the virtual machine and the first port using the virtual device and the first set of resources. The method further includes detecting an error in the first set of resources, deactivating the first set of resources and activating the second set of resources, and transferring data between the virtual machine and the second port using the virtual device and the second set of resources.
