    摘要: Migrating virtual machines among networked servers, the servers coupled for data communications with a data communications network that includes a networking device, where migrating includes: establishing, by a virtual machine management module (‘VMMM’), one or more virtual machines on a particular server; querying, by the VMMM, the networking device for link statistics of a link coupling the network device to the particular server for data communications; determining, by the VMMM in dependence upon the link statistics, whether the link coupling the network device to the particular server is degrading; and if the link coupling the network device to the particular server is degrading, migrating a virtual machine executing on the particular server to a destination server. In some embodiments, migrating occurs is carried out only if non-degrading link is available. If no non-degrading links are available, the network device, rather than the link, may be failing.
