Abstract:
1. A method of migrating virtual machines among networked servers, the servers coupled for data communications with a data communications network, the network comprising a networking device, the method comprising: establishing, by a virtual machine management module (‘VMMM’), one or more virtual machines on a particular server; determining, by the VMMM in dependence upon link statistics for a link coupling the network device to the particular server for data communications, 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, wherein link statistics for a link coupling the network device to the destination server indicate that the link coupling the network device to the destination server is not degrading.
