Abstract: In some examples, a bus device includes a device controller to perform input/output (I/O) virtualization to provide a virtualized instance of the bus device. The device controller establishes a channel between the virtualized instance of the bus device and a guest operating system (OS) of a virtual machine (VM). The device controller receives, from the VM, address information relating to a portion of a memory containing information associated with a kernel of the guest OS, and obtains, for integrity inspection, the information associated with the kernel from the memory based on the address information.
