摘要： A method for managing a multi-system shared memory includes: upon receiving a data write instruction for writing data to the shared memory, acquiring a data size of to-be-written data that is to be written to the shared memory; judging whether the shared memory includes a data block that matches the data size and is idle; if the shared memory does not include the data block that matches the data size and is idle, acquiring a first data block that has a memory size greater than the data size and is idle, such that the to-be-written data is written to the first data block; acquiring a remaining idle space of the first data block after the to-be-written data is written to the first data block; and generating a new data block based on the remaining idle space.

摘要： The present invention provides a method and apparatus for simultaneously running multiple virtual machines, and an electronic device. The method includes: initiating a request of running a second operating system in QEMU; triggering an exception to a Hypervisor of a currently running first operating system in a KVM module; storing a context of the Hypervisor of the first operating system in the Hypervisor of the first operating system, and loading the context of the Hypervisor of the second operating system; and storing the context of the first operating system in the Hypervisor of the second operating system, and loading the context of the second operating system. By adoption of the solution provided by the present application, multiple virtual machines can be run simultaneously, and the respective functions can be run independently.

摘要： The present application provides a context processing method and apparatus in a switching process of multiple virtual machines, and an electronic device. The method includes: in a KVM module, receiving a switching request of switching from a first Hypervisor to a second Hypervisor; in the KVM module, triggering an exception to the first Hypervisor; and in the first Hypervisor, storing a context of the first Hypervisor in a specified location, and loading the pre-stored context of the second Hypervisor. By adoption of the solution provided by the present application, multiple virtual machines can be run simultaneously, and the respective functions can be run independently.
