The method includes switching a network flow of a first para-virtualized network adapter kernel acceleration module to a user mode for transmission; removing the first para-virtualized network adapter kernel acceleration module; inserting a second para-virtualized network adapter kernel acceleration module; and switching a transmission of the network flow in the user mode to a transmission by the second para-virtualized network adapter kernel acceleration module. The method and the apparatus for upgrading a para-virtualized network adapter kernel acceleration module switches between a kernel mode and a user mode for a network flow without affecting fluctuations in a network flow of a virtual machine. An upgrade of a para-virtualized network adapter kernel acceleration module is achieved, which is unnoticeable by a user, and user experience is not affected."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for upgrading vhost-net module","description":"A method and an apparatus for upgrading a para-virtualized network adapter kernel acceleration module are disclosed.
