Abstract:
1. A method comprising: at a first computing apparatus in which a virtual server is running and is to be migrated to a second computing apparatus, monitoring on a continuing basis central processing unit processes and input/output processes of the virtual server; receiving a command to perform a live migration of the virtual server from the first computing apparatus to the second computing apparatus; changing a status of the virtual server from an active status to a migrate status in response to receiving the command; determining which one or more of the central processing unit processes and the input/output processes of the virtual server to modify based on the changing of the status; modifying one or more of the central processing unit processes and the input/output processes of the virtual server during the live migration so as to expedite transition of the virtual server from the first computing apparatus to the second computing apparatus; comparing an image file for the virtual server at the first computing apparatus and an image file for the virtual server at the second computing apparatus; and determining that the live migration is complete when the comparing indicates convergence of the image file for the virtual server at the first computing apparatus and the image file for the virtual server at the second computing apparatus.
