Descripción

*** Pendiente de traducción *** Addressing certain issues, in particular related to operations which may<br /> take excessively long and therefore would need preemption, has turned out<br /> overly costly. Since alternatives (HVM/PVH: HAP, PV: shim) are commonly<br /> available, the decision was to deprecate the functionality, while still<br /> retaining it for people to use at their own (security) risk. Memory-wise<br /> small enough guests may still be okay to run.
