Although L2 is in halt state, it will be in the active state after VM entry if the VM entry is vectoring according to SDM 26.6.2 Activity State. Halting the vcpu here means the event won't be injected to L2 and this decision isn't reported to L1. Thus L0 drops an event that should be injected to L2.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
