Abstract: Embodiments of this application disclose a virtual machine migration method. One example method includes: indicating, by a controller, a proxy virtual machine to mount a volume; replacing, by using the proxy virtual machine, a driver of an original platform in the volume with a driver of a target platform; and then, mounting a replaced volume to a target virtual machine.

Abstract: A method for a virtual machine to access a physical server in a cloud computing system is disclosed. A cloud platform allocates, to the service deployed on the physical server, a publishing IP address and a publishing port and sends a NAT rule to an access network element of the virtual machine. When receiving a service access request for accessing the service, the access network element modifies, according to the NAT rule, a destination address of the service access request into the IP address and the port that are of the physical server, and routes the modified service access request to the physical server, so that the virtual machine can access the service on the physical server without knowing a real IP address and port of the physical server.
