FIELD: physics, computer engineering.
SUBSTANCE: invention relates to virtualisation processing in a computer system. A computing node includes: a hardware layer, a host and at least one virtual machine (VM) running on the host, with several corresponding virtual function (VF) devices, obtained from an I/O device, the host has several VF software instances and several VF devices which 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.
EFFECT: providing compatibility of virtualisation means with devices used in a computer system.
