When filtering by guest, kvm_stat displays garbage when the guest is destroyed - see sample output below. We add code to remove the invalid paths from the providers, so at least no more garbage is displayed. Here's a sample output to illustrate: kvm statistics - pid 13986 (foo) Event Total %Total CurAvg/s diagnose_258 -2 0.0 0 deliver_program_interruption -3 0.0 0 diagnose_308 -4 0.0 0 halt_poll_invalid -91 0.0 -6 deliver_service_signal -244 0.0 -16 halt_successful_poll -250 0.1 -17 exit_pei -285 0.1 -19 exit_external_request -312 0.1 -21 diagnose_9c -328 0.1 -22 userspace_handled -713 0.1 -47 halt_attempted_poll -939 0.2 -62 deliver_emergency_signal -3126 0.6 -208 halt_wakeup -7199 1.5 -481 exit_wait_state -7379 1.5 -493 diagnose_500 -56499 11.5 -3757 exit_null -85491 17.4 -5685 diagnose_44 -133300 27.1 -8874 exit_instruction -195898 39.8 -13037 Total -492063 Signed-off-by: Stefan Raspl <raspl@linux.vnet.ibm.com> Signed-off-by: Radim Krčmář <rkrcmar@redhat.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
