Hi,
I working on an application in which I control an arbitrary process to
execute an a given code (injected code for example). I want the process I'm
controlling to execute my code with root privilege. Is it possible to
arbitrary switch vcpu cpl to 0 from the hypervisor level (process is in user
mode) ? I'm aware that I can do this using some hacks and emulation or by
controlling the process just after it enters or just before it quits kernel
mode (but I need to wait and intercept these events). Is there a
straightforward technique to switch vcpu cpl from the hypervisor level at
demand ?
