Abstract: A ring network system using peripheral component interconnect express (PCIe) is disclosed. The ring network system includes N PCIe bridges. Each of the N PCIe bridges is connected to an individual server and includes a first port and a second port. The second port of an ith PCIe bridge of the N PCIe bridges is connected to the first port of an ((i mod N)+1)th PCIe bridge of the N PCIe bridges. Each of the N PCIe bridges includes an address mapping chip. The address mapping chip of each of the N PCIe bridges configurably maps to a system address of each of at least portion of N servers connected by the N PCIe bridges and configurably maps to an address of each of at least portion of the N PCIe bridges for setting up a mapping relationship between the N PCIe bridges.

Abstract: A method for live migration of a virtual machine in a MR-IOV environment is provided. The method is used in a system, wherein the system includes a plurality of computing hosts, an MR-IOV device, and a management host including a physical function and configured to implement a plurality of virtual functions. Eand each computing host and the management host are coupled to the MR-IOV device. The method includes: migrating, by a source computing host of the computing hosts, a source virtual machine in the source computing host to a destination VM in a destination computing host of the computing hosts, wherein the source VM includes a source VF; transmitting, by the destination computing host, a request message to a management host and reassigning, by the management host, a first VF corresponding to the source VF in the management host to the destination VM according to the request message.
