OS: Ubuntu (Host)
Hypervisor: VirtualBox (7.0)
Since upgrading the Linux kernel header of Ubuntu 22.04 from 5.19 to 6.2 (and now 6.5), VirtualBox suddenly stopped working. As an employee in a local government agency, I have to be able to use Windows guest OS to use Microsoft 365 on my personal computer (which runs Ubuntu Desktop). In addition, I use VirtualBox to run Kali Linux and Ubuntu Server VMs. The break forced me to use earlier Linux headers (5.19) to allow me to run VirtualBox VMs.
Recently, I installed qemu to try to run VMs in the updated Linux kernel header. This hypervisor seemed fast and I was able to run Kali Linux and Windows 10 VMs easily. However, when I tried to install a VM for learning vulnerability scanning, the format of .vmdx is not easily accessible to qemu. I tried a lot of how-tos, to no avail. This forced me to go back to VirtualBox, which required me to run in the dated Linux kernel header.
Based on the last post (dated January 18) here, I though I would follow the logic. So I followed this:
I tried to run virtualbox from the terminal (virtualbox), which gave me the same error:
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
available for the current kernel (5.13.0-051300-generic) or it failed to
load. Please recompile the kernel module and install it by
sudo /sbin/vboxconfig
You will not be able to start VMs until this problem is fixed.
I tried the suggested command "sudo /sbin/vboxconfig". The machine gave me the same error, with additional line that if my system is using EFI Secure Boot, I may need to sign the kernel modules. That really sounded complicated. Also, I know my system does not use EFI Secure Boot.
I followed the guide to read the error log. Based on the error log, I saw that I could follow the logic to install gcc-12, so I did with:
sudo apt install gcc-12
Then I installed build-essentials:
sudo apt install build-essentials
Then I tried again
sudo /sbin/vboxconfig
The Virtual Box services were restarted.
I tried to run the VM from VirtualBox GUI: They worked!
