Abstract:
Methods and systems for improving performance in a virtualization environment. The method comprising: detecting, by a first software, a first set of features supported by a hardware device, wherein the first software runs on the hardware device; detecting a second set of features with which to run a second software, wherein the second software is launched by the first software with the second set of features; exposing one or more features in the second set of features to the second software, wherein the second software detects and enables the exposed features for a third software launched by the second software; and emulating a first feature without causing a trap such that control is transferred to the second software, in response to determining that the first feature is an exposed feature not included in the first set of features, wherein one or more sensitive events are associated with the first feature.
