Providing supplemental information to a guest operating system by a hypervisor

A host computing device, comprising:

• a memory;
• and
• a processor device coupled to the memory to:
• initiate, by a hypervisor, a virtual machine comprising a guest kernel;
• determine, by the hypervisor, an address of a shared memory area that is accessible by the guest kernel;
• determine, by the hypervisor, that an event has occurred for which supplemental information exists, the event corresponding to a particular event code;
• determine a location in the shared memory area that corresponds to the particular event code;
• insert the supplemental information at the location in the shared memory area;
• and
• cause, by the hypervisor, an interrupt of the guest kernel.

A non-transitory computer-readable storage medium that includes executable instructions to cause a processor device to:

• initiate, by a hypervisor, a virtual machine comprising a guest kernel;
• determine, by the hypervisor, an address of a shared memory area that is accessible by the guest kernel;
• determine, by the hypervisor, that an event has occurred for which supplemental information exists, the event corresponding to a particular event code;
• determine a location in the shared memory area that corresponds to the particular event code;
• insert the supplemental information at the location in the shared memory area;
• and
• cause, by the hypervisor, an interrupt of the guest kernel.
