Abstract
Providing supplemental information to a guest operating system by a hypervisor is disclosed. A hypervisor executing on a host computing device initiates a virtual machine comprising a guest kernel. The hypervisor determines an address of a shared memory area that is accessible by the guest kernel and accessible by the hypervisor. The hypervisor determines that an event has occurred for which supplemental information exists, the event corresponding to a particular event code of a plurality of different event codes. The hypervisor determines a location in the shared memory area that corresponds to the particular event code. The hypervisor inserts the supplemental information at the location in the shared memory area. The hypervisor causes an interrupt of the guest kernel.
