Imported Red Hat boots to black screen (virtual display issues)

Postby streamlinestabilizer » 17. May 2021, 17:59

Hello,

- VM Version 6.1.22 r144080 6.1.16 r140961 (Qt5.6.2)
- logs attached (3D acceleration OFF/ON)
- GA is installed in guest (6.1.16 r140961)
- host: Windows 10 64bit
- guest: Red Hat 64bit
- pc: HP Probook 6570b

I've been unable to get a Linux guest OS to boot properly after importing an existing VM. The VM was shared by a co-worker who has shared this VM before and others have been able to boot without issue. Initially, the guest OS would boot to a black screen and simply hang with the log showing the guest resolution resetting numerous times before hanging.
From "No login - 3D acc OFF - Centos 8 Dev environment-2021-05-17-10-48-20.log":
00:04:51.697552 Display::i_handleDisplayResize: uScreenId=0 pvVRAM=0000000000000000 w=800 h=600 bpp=0 cbLine=0x0 flags=0x2 origin=0,0
00:04:51.853978 Display::i_handleDisplayResize: uScreenId=0 pvVRAM=000000000d480000 w=800 h=600 bpp=32 cbLine=0xC80 flags=0x1 origin=0,0
00:04:51.854770 GUI: UIMachineLogic: Guest-screen count changed
above repeated 5 more times over 1min


I tried changing numerous settings with no luck until enabling 3D acceleration. After enabling 3D acceleration, the guest OS will boot to the login screen, however, logging in with the correct password will hang the guest OS on a black screen. The log seems to show the virtual display turns off after logging in:
From "Login screen - 3D acc ON- Centos 8 Dev environment-2021-05-17-11-01-10.log":
00:01:58.443145 Audio Mixer: Setting recording source of sink '[Recording] Line In' to '[Line-In] DirectSound'
00:03:38.828171 Display::i_handleDisplayResize: uScreenId=0 pvVRAM=0000000000000000 w=800 h=600 bpp=0 cbLine=0x0 flags=0x2 origin=0,0


Any ideas on what may be causing the issue?

There are two similar posts from what I could find referencing an observation about the guest display made by fth0, but the solutions mentioned in each aren't working for my situation:
Black screen stuck at startup of Xubuntu posted by apotheosis27
Black Screen on boot up posted by BattleFrog36

I have Hyper-V disabled in Windows settings. Aside from 3D acceleration, here is a list of options I have tried at this point:
- Setting base memory to 4096 MB / 10240 MB
- Setting processors to 1 CPU / 2 CPUs
- Setting Paravirtualization interface to Default / None / KVM
- Setting video memory to 12 MB / 128 MB / 256 MB
- Setting the Graphics controller to VMSVGA / VBoxVGA
- Resizing the guest window when hanging
- Uninstall/reinstall Virtualbox
- Installing other versions of Virtualbox (5.2 / 6.0 / 6.1.22 r144080)
- Re-downloading the imported environment

Well, I would have suggested reducing the base memory, but you already tried that. The video drivers in the host OS and the guest OS would be candidates for changes, too.

You could "disable" the VirtualBox Guest Additions (GA) by booting the guest OS from a Linux Live ISO and renaming all vbox*.ko* files in the /lib/modules tree, so that the VirtualBox kernel modules won't be found on the next regular boot of the guest OS. If this helps, you could then install the matching GA version 6.1.22.

Would changing my version of Virtualbox to match the GA produce the same effect? I changed my version of Virtualbox to 6.1.16 r140961 to match the currently installed GA (which is 6.1.16 r140961, for the sake of clarity) and imported the VM environment again, however, this didn't change the result. My co-worker also uses this version and the VM runs for him.

I asked my co-worker for his log and he sent me his recorded log after logging in and reaching the desktop. Note: the log was taken while the VM was still running, so it doesn't include the shutdown logging. His log seems to show the same message at login as mine (GA compatibility report), and also includes repeated "guest-screen count changed" messages except after login. The difference in the repeated guest-screen count messages is that his log shows PerformGuestResize, SetVideoModeHint, and UIMediumEnumerator messages in between the guest-screen count changes (bolded below)

I don't want to start a competition here ;), but your co-worker has a Dell Latitude E6540 with a display resolution of 1920x1080, and you have a HP ProBook 6570b with a display resolution of 1366x768. Your VM starts under a wrong assumption:

No login - 3D acc OFF - Centos 8 Dev environment-2021-05-17-10-48-20.log wrote:
00:00:08.113684 GUI: UIMachineViewNormal::resendSizeHint: Restoring guest size-hint for screen 0 to 1920x950

Restart your Windows host, open a Windows command prompt and execute the following command:

Code: Select all   Expand viewCollapse view
"C:\Program Files\Oracle\VirtualBox\VBoxManage" setextradata "Centos 8 Dev environment" "GUI/LastGuestSizeHint" "1280,720"

Afterwards, start the VM. If the problem persists, post a new VBox.log file. Please also report back if the problem is solved.

If there was a competition, they'd have me beat :)
No luck, unfortunately. The command executed, and I can see the change reflected in the log, but the same issue occurs. Attached are logs for two sessions with 3D acceleration ON and OFF.

Re: Imported Red Hat boots to black screen (virtual display issues)

Postby fth0 » 18. May 2021, 17:06

Please provide the output of the following commands:
Code: Select all   Expand viewCollapse view
"C:\Program Files\Oracle\VirtualBox\VBoxManage" getextradata "Centos 8 Dev environment" "GUI/LastGuestSizeHint"
"C:\Program Files\Oracle\VirtualBox\VBoxManage" getextradata "Centos 8 Dev environment" "GUI/LastNormalWindowPosition"
"C:\Program Files\Oracle\VirtualBox\VBoxManage" getextradata global "GUI/MaxGuestResolution"

The value of MaxGuestResolution may be empty. If the value of LastNormalWindowPosition ("x,y,w,h") results in a window specification larger than your display resolution, use an appropriate setextradata command to set some sensible values (e.g. "100,100,800,450"). It doesn't matter if they match the LastGuestSizeHint value. You can also try if the following command helps:

Code: Select all   Expand viewCollapse view
"C:\Program Files\Oracle\VirtualBox\VBoxManage" setextradata global "GUI/MaxGuestResolution" "1366,768"

Note that this constrains the window, so if you connect a larger display to your notebook in the future ... ;)

MaxGuestResolution was not set to a value, so I set it to 1366,768 (keeping in mind connecting to external monitors in the future). LastNormalWindowPosition and LastGuestSizeHint seem to be fine at their current values, although I'm not sure what max refers to in LastNormalWindowPosition. I ran the VM after setting MaxGuestResolution, but still no luck. Attached is a log of the recent run with 3D acceleration ON.

Code: Select all   Expand viewCollapse view
> "C:\Program Files\Oracle\VirtualBox\VBoxManage" getextradata "Centos 8 Dev environment" "GUI/LastGuestSizeHint"
Value: 1280,720

> "C:\Program Files\Oracle\VirtualBox\VBoxManage" getextradata "Centos 8 Dev environment" "GUI/LastNormalWindowPosition"
Value: 0,29,640,480,max

> "C:\Program Files\Oracle\VirtualBox\VBoxManage" getextradata global "GUI/MaxGuestResolution"
Value: 1366,768

I also tried setting LastNormalWindowPosition to the example value you posted, then tried setting MaxGuestResolution to auto, but same outcome for both cases.

Ok, the current strategy seems to be a dead end. The latest VBox.log file still shows that the display is turned off (as you initially discovered), but the rest of it now looks ok to me.

What happens if you change the screen resolution on the host before starting the VM?

What happens if you change the screen resolution via the View menu of the VirtualBox VM window (incl. switching from/to Full-screen Mode)?

What happens if you change the screen resolution inside the guest OS by switching between virtual terminals?

Another thing to try: Uninstall the VirtualBox Guest Additions (GA), update VirtualBox to the current version 6.1.22 and install the matching GA.

Trying the screen resolution changes didn't change the outcome and the logs don't seem to show much either. Changing screen resolution via the View menu produces sltPerformGuestResize and SetVideoModeHint messages, and changing screen resolution by switching to virtual terminals produces the repeated "Guest-screen count changed" and i_handleDisplayResize messages as seen when 3D acceleration is turned off. Logs are attached for the three cases tested.

I'm going to try updating the GA, although I ran into trouble earlier on my first attempt. I'll try again and update as I go.

Note: Virtualbox has been updated to 6.1.22

After uninstalling GA from the guest OS, running rcvboxadd setup, as well as rcvboxdrv setup, displays "command not found" in the terminal. Attempting to install GA 6.1.22 as per the instructions given in the manual produces the message:

Code: Select all   Expand viewCollapse view
VirtualBox Guest Additions: Look at /var/log/vboxadd-setup.log to find out what went wrong
VirtualBox Guest Additions: Running kernel modules will not be replaced until the system is restarted


Inspecting vboxadd-setup.log shows the message:

Code: Select all   Expand viewCollapse view
ERROR: Kernel configuration is invalid.
include/generated/autoconf.h or include/config/auto.conf are missing.
Run 'make oldconfig && make prepare' on kernel src to fix it.


Not quite sure what to make of this yet, so continuing to investigate.

Edit: I tried following the instructions at this link:
https://www.if-not-true-then-false.com/2010/install-virtualbox-guest-additions-on-fedora-centos-red-hat-rhel/

I wasn't able to complete steps 2 and 4 completely as yum tried downloading bintray-rabbitmq-rpm which would throw a 403 error. I tried connecting to my company's VPN but still no luck, however, I was able to complete the other steps in the guide. Afterwards, uninstalling then attempting to reinstall the GA produced a new message:

Code: Select all   Expand viewCollapse view
VirtualBox Guest Additions: Look at /var/log/vboxadd-setup.log to find out what went wrong
ValueError: File context for /opt/VBox/GuestAdditions-6.1.22/other/mount.vboxsf already defined


Still no luck with reinstalling GA. The investigation continues.

The idea was to follow my suggestions in the order given (at least inside this last one). This wouldn't have allowed you to test everything with the combination of VirtualBox 6.1.22 and the VirtualBox Guest Additions 6.1.16, where you cannot rely on the internal communications between those two softwares to work reliably. Don't get me wrong: Your problem may not be related to this, but it could be, at least partially. So the results don't prove anythingmuch.

Since you have problems installing the GA 6.1.22, perhaps the installation of the GA 6.1.16 was flawed somehow. I believe I've seen your quotes regarding autoconf.h in these forums in the past, perhaps you could google for "site:forums.virtualbox.org centos autoconf.h" ...
