AbstractAbstractHeThis paper presents a transient analysis of software rejuvenation with virtualization. In particular, we apply the phase-type expansion to analyze the pointwise availability of virtual-machine (VM) based software rejuvenation with two policies; cold-VM and warm-VM rejuvenation policies. The performance measures can be derived from the stochastic models described by labeled Markov regenerative stochastic Petri Nets (MRSPNs).Key Words: Markov regenerative stochastic Petri Netphase-type expansionsoftware rejuvenationtransient analysisvirtualized system.
