A first and second node may be identified effective to access the virtual machine at a first computing device. First and second vectors related to the first and second nodes, respectively, may be determined. The first and second vectors may relate to values of a parameter. The parameter may relate to communication between the nodes and the first computing device. The vectors may form a distribution. A feature of the distribution of the vectors may be determined. A first magnitude between the first computing device and the feature may be determined. A second magnitude between the second computing device and the feature may be determined. The virtual machine may be migrated from the first computing device to the second computing device if the second magnitude is less than the first magnitude.
