Abstract: Cross-hypervisor virtual machine conversion. A set of disk images that define a source virtual machine (VM) in a source host computing environment is determined. For each respective disk image, a corresponding overlay image that references the respective disk image is generated. The overlay image that corresponds to a boot disk image is altered to enable a target VM process to be booted from the overlay image on a target host computing device that utilizes a second type of hypervisor. A target VM process that boots from the overlay image that corresponds to the boot disk image is initiated, and the target VM process is configured to access the set of disk images indirectly via the corresponding overlay images.

Abstract: A device may receive, from a virtual machine deployed on the device, a request to register for an event associated with a hardware component of the device, and may create a path to a script associated with providing information about the event when the event occurs. The device may provide the script to an event plugin associated with the event and the hardware component, and may register the event plugin with a kernel associated with the device. The device may receive, the kernel, information indicating occurrence of the event associated with the hardware component, and may cause, via the event plugin, execution of the script based on the occurrence of the event associated with the hardware component. The device may provide, based on execution of the script, a notification to the virtual machine, where the notification may indicate the occurrence of the event associated with the hardware component.

Abstract: A method and apparatus of a device for resource management by using a hierarchy of resource management techniques with dynamic resource policies is described. The device terminates several misbehaving application programs when available memory on the device is running low. Each of those misbehaving application programs consumes more memory space than a memory consumption limit assigned to the application program. If available memory on the device is still low after terminating those misbehaving application programs, the device further sends memory pressure notifications to all application programs. If available memory on the device is still running low after sending the memory pressure notifications, the device further terminates background, idle, and suspended application programs. The device further terminates foreground application programs when available memory on the device is still low after terminating the background, idle, and suspended application programs.
