In order to let a VLPI being injected into a guest, the VLPI must be mapped using the VMAPTI command. When moved to a different vcpu, it must be moved with the VMOVI command. These commands are issued via the irq_set_vcpu_affinity method, making sure we unmap the corresponding host LPI first. The reverse is also done when the VLPI is unmapped from the guest.

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.
