Abstract
A solution is proposed for maintaining virtual machines being available in a data-processing system. A mechanism determines a list of software components installed on each virtual machine, retrieves a set of maintenance policies for each software component, each maintenance policy being indicative of a patch to be applied to the corresponding software component. The mechanism determines a set of old virtual machines having at least one old software component thereof requiring the application of at least a new one of the corresponding patches according to a comparison among the maintenance policies and a maintenance register indicative of a current state of the software components of the virtual machines. The mechanism applies the corresponding at least one new patch to each old software component of each old virtual machine and updates the maintenance register according to the application of said at least one new patch to each old software component of each old virtual machine.
