RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Xueqiang Wei 2020-03-01 14:41:52 UTC 
Description of problem:

In order to check "Auto Boot Time-out" in debug log, request to add this function.
 
Discussed with Laszlo, he will write DEBUG messages for the
GetFrontPageTimeoutFromQemu() function. Then the OVMF debug log (on the
host side) would report the value, and I can grep for it.



Version-Release number of selected component (if applicable):

kernel-4.18.0-175.el8.x86_64
qemu-kvm-4.2.0-10.module+el8.2.0+5740+c3dff59e
edk2-ovmf-20190829git37eef91017ad-8.el8.noarch



How reproducible:


Steps to Reproduce:
1. boot a guest with -boot menu=on,splash-time=12000
2. Check "Boot Maintenance Manage"->"Auto Boot Time-out".



Actual results:
after step 2, can't grep for it in debug log


Expected results:
get it in debug log

Comment 3 Laszlo Ersek 2020-03-04 09:11:19 UTC 
Xueqiang Wei,

I have some patches to post to the upstream list. Here's the behavior to
expect from OVMF:


(1) When "-boot menu=(on|off)" is not specified at all (equivalently,
    when the libvirt domain XML has no <bootmenu/> element),

    *or* when "-boot menu=off" is specified on the QEMU command line
    (equivalently, when the libvirt domain XML says <bootmenu
    enable='no'/>),

    then

   - there is no progress bar shown at the TianoCore splash screen: the
     boot is immediate,

   - the OVMF debug log will contain:

> PlatformBootManagerBeforeConsole: SetVariable(Timeout, 0): Success

    - in the UEFI shell, the "setvar Timeout" command will output

> 8BE4DF61-93CA-11D2-AA0D-00E098032B8C - Timeout - 0002 Bytes
> 00 00

    - in a Linux guest, the "efibootmgr" command will output

> Timeout: 0 seconds


(2) When "-boot menu=on" is specified on the QEMU command line, but
    "splash-time=N" is not (equivalently, when the domain XML says
    <bootmenu enable='yes'/> but there is no timeout='N' attribute),
    then:

    - the progress bar takes 3 seconds,
    - the OVMF debug log and the "efibootmgr" output will report 3
      seconds,
    - the "setvar" UEFI shell command will report:

> 8BE4DF61-93CA-11D2-AA0D-00E098032B8C - Timeout - 0002 Bytes
> 03 00

      (2-byte little endian representation printed in hex).


(3) When "-boot menu=on,splash-time=NNNN" is specified on the QEMU
    command line (equivalently, when the domain XML says <bootmenu
    enable='yes' timeout='N'/>), and N is a positive number of
    milliseconds, then

    - the number of seconds taken by the progress bar, and
    - reported in the OVMF debug log, in the UEFI shell, and by
      efibootmgr,

    is calculated by rounding up N to whole seconds.
