Abstract
One or more kernel-modifying procedures are stored in a trusted computing base (TCB) when bringing up a guest operating system (OS) on a virtual machine (VM) on a virtualization platform. When the guest OS invokes an OS-level kernel-modifying procedure, a call is made to the hypervisor. If the hypervisor determines the TCB to be valid, the kernel-modifying procedure in the TCB that corresponds to the OS-level kernel-modifying procedure is invoked so that the kernel code can be modified.
