Abstract
A virtualization processing method and apparatuses, and a computer system are provided. Where a computing node includes: a hardware layer, a Host running on the hardware layer, and at least one virtual machine (VM) running on the Host, the hardware layer includes an I/O device, several corresponding virtual function (VF) devices are virtualized from the I/O device, the Host has several VF software instances, the several VF software instances and the several VF devices are in one-to-one correspondence; the Host further has a back-end instance (BE) of an I/O virtual device having the same type with the I/O device, the VM has a front-end instance (FE) of the I/O virtual device; the BE in the Host is bound with an idle VF software instance. The solutions of the embodiments of the present invention are beneficial to optimization of the performance and compatibility of a virtualization system.
