Unable to install Guest Additions on AlmaLinux OS 8.8 => fixed in svn

[almalinux_cloud_sig]

AlmaLinux OS is 1:1 binary compatible with RHEL.

Tested these Guest Additions ISOs:

• ​https://download.virtualbox.org/virtualbox/7.0.8/VBoxGuestAdditions_7.0.8.iso
• https://www.virtualbox.org/download/testcase/VBoxGuestAdditions_7.0.97-157540.iso

Steps to reproduce:

# Get AlmaLinux OS 8.7 Vagrant Box with Guest Additions version 6.1.40
vagrant init almalinux/8

# Create the VM
vagrant up

# Connect the VM
vagrant ssh

# Upgrade the AlmaLinux OS version from 8.7 to 8.8
sudo dnf clean all && sudo dnf -y upgrade

exit

# Reboot system to AlmaLinux OS 8.8 kernel (4.18.0-477.10.1.el8_8)
vagrant reload

# Connect the VM again
vagrant ssh

# Remove AlmaLinux OS 8.7 kernel
sudo dnf -y remove --oldinstallonly

# For 7.0.8 Stable
curl -LO https://download.virtualbox.org/virtualbox/7.0.8/VBoxGuestAdditions_7.0.8.iso

# For Test Build
curl LO https://www.virtualbox.org/download/testcase/VBoxGuestAdditions_7.0.97-157540.iso

# Mount the Guest Additions ISO
sudo mount -o loop VBoxGuestAdditions_7.0.8.iso /mnt

# Install the dependencies for Guest Additions

sudo dnf -y install elfutils-libelf-devel \
    gcc \
    kernel-devel \
    kernel-headers \
    make \
    perl \
    binutils \
    bzip2


Install the Guest Additions without GUI
sudo /mnt/VBoxLinuxAdditions.run --nox11

Attached the log files.

Thanks!

Hi almalinux_cloud_sig,

This issue should be fixed on development branch. Could you please give it a try to one of the "Latest 7.0.x test builds" (r157689+) on Test Builds page?

"Latest 6.1.x test builds" should also have the fix (r157688+).

[almalinux_cloud_sig]

Hi galitsyn,

Thanks a lot!

Looks like, the issue still exist on the latest test build.

The only difference that we got an update for kernel; 4.18.0-477.10.1.el8_8 -> 4.18.0-477.13.1.el8_8:

[vagrant@localhost ~]$ sudo dnf list --installed | grep -Ei 'kernel'
kernel.x86_64                       4.18.0-477.13.1.el8_8                   @baseos   
kernel-core.x86_64                  4.18.0-477.13.1.el8_8                   @baseos

kernel-tools.x86_64                 4.18.0-477.13.1.el8_8                   @baseos

You can check the changes on the new version here - ​https://git.almalinux.org/rpms/kernel/commit/775fe6924aa2366d41ee5a855b2d4d8f3f360da6

Attached the new log files with _7.0.9-157689 suffix.

I will test the 6.1.x version too and let you know.

[galitsyn]

Hi almalinux_cloud_sig,

Did you install VBox host package 7.0.9 r157689 or Additions ISO r157689? You need to pick up latest ISO from the "Latest 7.0.x test builds". Installer package does not have it included in this build. Same for 6.1 builds.

[almalinux_cloud_sig]

Hi galitsyn,

I downloaded and installed this file:

https://www.virtualbox.org/download/testcase/VBoxGuestAdditions_7.0.9-157689.iso

[galitsyn]

Hi almalinux_cloud_sig,

Thank you for the confirmation. I see that mentioned fixes only cover EL 8.9 kernel, not EL 8.8 as in your case. I will update test builds later today and leave a comment here.

[almalinux_cloud_sig]

Hi galitsyn,

Thanks a lot for fast replies!

Sounds great!

[galitsyn]

Hi almalinux_cloud_sig,

Additions test builds should now be in place. Please use:

• r157700+ for Development snapshots,
• r157701+ for Latest 6.1.x test builds, and
• r157702+ for Latest 7.0.x test builds.

[almalinux_cloud_sig]

Hi galitsyn,

Thanks for the test results. I uploaded the logs with these suffixes:

• _7.0.97-157700 (Development snapshots)
• _7.0.9-157702 (Latest 7.0.x test builds)
• _6.1.45-157701 (Latest 6.1.x test builds)

As far as I observed, All of the installations went fine.

One nuance is the installation of _7.0.97-157700 (Development snapshots) and _7.0.9-157702 (Latest 7.0.x test builds) builds freezes. I need to reboot the machine.

Here some outputs about the current status of the Guest Additions: Please, let me know if you want additional outputs.

Hi almalinux_cloud_sig,

Thank you for the logs. A few questions though.

1. Installation or uninstalation should not freeze. If you face it again, could you please take a look on "ps -AF" and check what processes (related to the installation process/script) are running. It might be that building modules takes significant time, especially if system has number of kernels installed.

2. In "7.0.9-157702 (Latest 7.0.x test builds)" dmesg snippet I see a backtrace from vboxvideo:

   [    2.400699]  vboxfb_create+0x26c/0x350 [vboxvideo]
   [    2.400794]  vbox_fbdev_init+0x81/0xa0 [vboxvideo]
   [    2.400802]  vbox_driver_load+0x3da/0x450 [vboxvideo]
   [    2.400810]  vbox_pci_probe+0x5c/0x90 [vboxvideo]
   

Could you please post complete backtrace/oops output?

3. In vboxadd-setup.log_6.1.45-157701.3, vboxadd-setup.log_7.0.9-157702.2 and vboxadd-setup.log_7.0.97-157700.2 I see that modprobe of vboxguest was failed. Do you have more details from dmesg? Does the guest run with secure boot enabled?

Hi galitsyn,

Thanks for tracking down the problem.

1. Actually, the machine freezes on the reloading of kernel modules rather than the building of them. When it happens, it is impossible to connect to this machine and do "ps -AF".

All the process done on the single and latest kernel of 8.8:

# dnf list --installed | grep -Ei 'kernel'
kernel.x86_64                       4.18.0-477.13.1.el8_8                   @baseos
kernel-core.x86_64                  4.18.0-477.13.1.el8_8                   @baseos
kernel-devel.x86_64                 4.18.0-477.13.1.el8_8                   @baseos
kernel-headers.x86_64               4.18.0-477.13.1.el8_8                   @baseos
kernel-modules.x86_64               4.18.0-477.13.1.el8_8                   @baseos
kernel-tools.x86_64                 4.18.0-477.13.1.el8_8                   @baseos
kernel-tools-libs.x86_64            4.18.0-477.13.1.el8_8                   @baseos

I upgraded the VM from 1vCPU,1GB RAM(Vagrant's default) to 2vCPU,2GB RAM but didn't make any difference.

2. The first boot doesn't have this backstrace but the second has.

The First Boot:

• dmesg.txt
• systemd_journal.txt
• lsmod.txt

The Second Boot:

• dmesg_2.txt
• systemd_journal_2.txt
• lsmod_2.txt

3. As I mentioned on the body of ticket beside the steps to reproduce the issue, the guest is vagrant box of AlmaLinux OS available on ​https://app.vagrantup.com/almalinux/boxes/8. This box is BIOS only.

Couldn't upload the systemd_journal_2.txt file due the size limitation (377.8 kB).

Hi galitsyn,

Any updates? Please, Let me know if you need anything else.

[galitsyn]

Hi almalinux_cloud_sig,

Nothing catches my eye in the logs (except a backtrace). I wonder if you hit kernel panic on modules reloading. Is it possible to get guest dmesg during installation (see https://www.virtualbox.org/wiki/Serial_redirect)?

Btw, if you do "sudo rcvboxadd reload" manually after installation / next boot -- does it succeed?

Regarding to backtrace, I need to get Almalinux VM locally, this will take some time. I think backtrace should be gone if you change graphics adapter to VMSVGA for example.

Hi almalinux_cloud_sig,

Just FYI. https://www.virtualbox.org/ticket/21740#comment:13

[almalinux_cloud_sig]

Hi galitsyn,

We just released the first version of AlmaLinux OS 8.8 Vagrant box for VirtualBox provider with https://www.virtualbox.org/download/testcase/VBoxGuestAdditions_7.0.9-158050.iso and VMSVGA as Graphic Controller workaround.

See: ​https://app.vagrantup.com/almalinux/boxes/8/versions/8.8.20230606

Thanks a lot!
