QEMU spapr (SLOF) does NOT honor -boot once=d as a true one-shot: SLOF
caches the chosen boot device in spapr-NVRAM, so the post-install
reboot loops back into the installer (E3405: No such device at scsi@8:1
once anaconda has finished using the CD). The previous patch (commit
58f6db9) dropped the arch_supports_boot_order=0 line from this patch
to fix install tests that supply both an ISO and a populated HDD_1
(install_resize_lvm), but it broke the default install_default
post-install reboot.
Switch to a model that handles both cases:
- Default ppc64le: arch_supports_boot_order = 0. No -boot args at all.
Empty HDD falls through to the installer CD on first boot; populated
HDD boots its own bootloader on subsequent boots. Matches AL9 behavior.
- ISO + populated HDD_1 needing CD-first (install_resize_lvm): test
sets BOOTFROM=d. The patch translates this into -boot once=d *and*
clears $bootfrom so Proc::configure_blockdevs() does NOT assign a
persistent bootindex(0) to the CD. once=d is the only boot flag
whose effect doesn't outlive the first guest boot in this setup,
giving us 'CD wins first boot, default order on second boot'.
The companion fix for the AL10 anaconda-40.22 NVRAM-write regression
lives in os-autoinst-distri-almalinux's _boot_to_anaconda.pm
(inst.leavebootorder).
Replace 0001-Add-AArch64-and-ppc64le-support-to-QEMU-backend.patch with
0001-Add-AArch64-ppc64le-s390x-support.patch. Keeps the existing AArch64
and ppc64le tweaks (including the ppc64le arch_supports_boot_order fix
from -4) and adds s390x:
- virtio-keyboard for s390x and ppc64le (via $use_virtio_kbd)
- virtio-rng (CCW) instead of virtio-rng-pci on s390x
- virtio-tablet + no usb-tablet on s390x and ppc64le
- Gate audio and floppy devices out on s390x as well
- PXE bootindex=$i on NIC devices when PXEBOOT is set
- BOOTFROM=n/net parsing for network boot
- virtio-gpu added to EDID-capable device list
- Drop unused save_storage_drives sub
- Default _serialdev=ttysclp0 when ARCH=s390x + BACKEND=qemu

No fuzz, no offsets.
QEMU spapr/pseries honors -boot once=d / order=, so leaving
$arch_supports_boot_order disabled on ppc64le made install tests
that supply both an ISO and an HDD_1 boot the HDD instead of the
installer CD (same symptom as running x86_64 without -boot). Drop
that line from the patch so ppc64le behaves like x86_64.
Patch description updated to record the history; hunk shrinks by
one line and the patch diffstat updates accordingly.
Patch by Elkhan Mammadli <elkhan.mammadli@protonmail.com>. Adjusts the
QEMU backend for the QEMU build shipped in Enterprise Linux on AArch64
and ppc64le: use qemu-xhci on AArch64, wire virtio keyboard/tablet on
ppc64le, disable audio, and skip unsupported boot-order and floppy
handling.
