Activating continuous world switch security for tasks to allow world switches between virtual machines executing the tasks

摘要

Technologies related to continuous world switch security are generally described. In some examples, a world switch indicator may indicate whether continuous world switch security is on or off for a cloud customer. A hypervisor world switch security setting may be activated and deactivated, according to the world switch indicator, to optionally allow world switches and not context switches between virtual machines executed by a cloud server. Continuous world switch security may optionally be controlled by a cloud customer. Load balancing, cloud customer billing and other techniques are also disclosed to accommodate the activation/deactivation of continuous world switch security.
