Automatic system test technology of virtual machine software patch on IaaS cloud

Regarding IaaS virtual machine operations, the problem is its high operation costs because users need to distribute and verify software patches for their virtual machines. We proposed an automatic verification technology for each virtual machine patch in our previous work. In this paper, we study an improvement of automatic verifications of system tests with plural virtual machines. © 2015 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
