#18931 invalid VirtualBox very often fails at booting OS/2 Warp guests mcandre
Description

About 50% of the time, guests configured OS/2, eComStation, etc. fail to boot correctly. A typical OS/2 Warp 4.0 guest, for example, will show a black screen with a blinking cursor instead any of the usual boot splashes. This significantly impacts the usefulness of the VirtualBox hypervisor.

As a workaround in my Packer and Vagrant scripts, I am retrying a whole lotta boots. A three-boot process just to install OS/2 Warp has a success rate of 12.5% (yuck!)

#18926 fixed Problem loading vboxsf.ko after upgrade to 6.0.12 Frank Batschulat (Oracle) alealeale
Description

$ uname -r
4.1.12-124.31.1.el6uek.x86_64

$ cat /etc/oracle-release
Oracle Linux Server release 6.10

After upgrading from 6.0.10 to 6.0.12 (+Guest Additions), shared folders are not available (mounted) anymore.

Trying to manually loading the module I'm getting (in /var/log/message):
vboxsf: Unknown symbol noop_backing_dev_info (err 0)

Just for fun, I tried rebuilding VBoxGuestAdditions after applying the following patch and rebuilding VBoxGuestAdditions, and now I'm able to load the module and mount my shared folders.

I know that shouldn't be the way to fix the problem...maybe the commented IF should be verified against 4.1.12-124.31.1.el6uek src(?).

Please let me know if you need any test in order to fix the problem.

I am trying to install VirtualBox 6.0.12 on RHEL 8.0

I used the file

this throws the error below.
