The timezone fixes are:

commit 597d177567234c3a539098c423649781424eeb6f
Author: Laszlo Ersek <lersek at redhat.com>

    convert_windows: rewrite "configure_qemu_ga" script purely in
PowerShell

commit d9dc6c42ae64ba92993dbd9477f003ba73fcfa2f
Author: Richard W.M. Jones <rjones at redhat.com>
Date:   Fri Nov 12 08:47:55 2021 +0000

    convert/convert_windows.ml: Handle date formats with dots instead of /

They are all included in >= 2.0

I wonder if 597d177567 has a subtle flaw, or if we introduced a bug
somewhere when refactoring this code later.

Lee: Do you have a theory about exactly what is wrong with the
schtasks date?  Like what was it supposed to be, assuming it was 120
seconds in the future from boot time, versus what it was set to:
> Firstboot-qemu-ga                        9/21/2023 4:04:00 PM   Ready
Could a date or time field have not been swapped or been corrupted
in some predictable way?

The code we run is here:

https://github.com/libguestfs/libguestfs-common/blob/e70d89a58dae068be2e19c7c21558707261af96a/mlcustomize/inject_virtio_win.ml#L571

Ming: this could be a bug affecting PST (UTC-8) guests, perhaps
somehow related to having a single digit month field?

Rich.

Or in even simpler terms, what is the time (and timezone) that
this ^^^ machine was booted?

[Libguestfs] Fwd: virt-v2v creating image that does not install guest agent on first boot

Hi Richard,

       Sorry, I missed the email, I found out that the ova OS used by the
customer is win11 uefi, so I tried to reproduce the error today using
win11-uefi guest

Steps:
1. Convert win10-efi with UTC-8 timezone, win11-non-efi with UTC-8
timezone, win11-efi with UTC-8 timezone, win11-efi with UTC+8 timezone,
win2022-efi with UTC-8 timezone from VMware by v2v, then check the
installation status after finishing conversion


Summary the test result as below:

                                            qemu-ga

  Win10-efi-UTC-8              PASS
  Win11-non-efi UTC-8       PASS
  Win11-efi-UTC-8              FAIL(can't find qemu-ga log in c:\)
  Win11-efi-UTC+8             FAIL(can't find qemu-ga log in c:\)
  Win2022-efi-UTC-8          PASS

  Based on the above results, I think this problem is only caused by
win11-efi and has nothing to do with the time zone "UTC-8"

The following are existing bugs about qemu-ga:

*Bug 1820144* <https://bugzilla.redhat.com/show_bug.cgi?id=1820144> -
cannot
install qemu-ga to some guests even if scheduled qemu-ga installation task
exist
*Bug 2114809* <https://bugzilla.redhat.com/show_bug.cgi?id=2114809> -
Can't
install qemu-ga because of network address error after converting MD-RAID1
win11 host by virt-p2v
*Bug 1820152* <https://bugzilla.redhat.com/show_bug.cgi?id=1820152> - Fail
to execute installation-qemu-ga.msi for win2012r2 and win8.1-i386 guests


Thanks & Regards
Ming Xie
