Host-to-guest channel for guest device identification

摘要

A method and system for providing a descriptive name of a device in a virtual machine system. A computer system hosts a hypervisor, a management component and a guest. The hypervisor receives from the management component a descriptive name of a device available to the guest. The descriptive name defines at least one of the functionality of the device, the content of the device, or a user of the device. The hypervisor then passes the descriptive name to the guest via a host-to-guest channel, which is a shared storage location writable by the hypervisor and readable by the guest.

identifying, by a hypervisor of the computer system, a descriptive name of a device available to a guest hosted by the computer system, the descriptive name being automatically determined by a management component of the computer system using one or more rules specifying that the descriptive name is to include at least one of functionality of the device, content of the device, or a user of the device; and passing, by a processing device executing the hypervisor, the descriptive name to the guest via a host-to-guest channel, the host-to-guest channel being a shared storage location writable by the hypervisor and readable by the guest.
