Fedora 26 + Virtualbox 5.1 + kenel 4.12

Upgrading your virtual machine (VM) environment can sometimes lead to unexpected issues. A common problem users might encounter after upgrading VirtualBox is the VM failing to start. In this post, we'll walk through a specific error and provide a step-by-step guide to resolve it, ensuring your virtual environment gets back up and running smoothly.

Understanding the Error

Upon attempting to start a VM after an upgrade, you might encounter an error in your logs similar to this:

/tmp/vbox.0/r0drv/linux/memuserkernel-r0drv-linux.o: warning: objtool: .fixup: unexpected end of section if [ "-pg" = "-pg" ]; then if [ /tmp/vbox.0/r0drv/linux/memuserkernel-r0drv-linux.o != "scripts/mod/empty.o" ]; then ./scripts/recordmcount "/tmp/vbox.0/r0drv/linux/memuserkernel-r0drv-linux.o"; fi; fi; make[1]: *** [Makefile:1519: _module_/tmp/vbox.0] Error 2 make: *** [Makefile:304: vboxdrv] Error 2

This error typically indicates a problem with the VirtualBox kernel modules not compiling or loading correctly due to incompatibilities or issues within the system.

Step-by-Step Solution

Fear not, as this issue can often be resolved by applying a patch to the VirtualBox source. Here's how you can fix it:

1. Change to the VirtualBox Source Directory:

Navigate to the directory where VirtualBox sources are stored:

cd /usr/share/virtualbox/src

2. Obtain the Necessary Patch:

Download the patch designed to fix the issue:

sudo wget http://paste.siduction.org/20170629003423

3. Apply the Patch:

Apply the downloaded patch to the VirtualBox source:

sudo patch -Np0 < 20170629003423

4. Reconfigure VirtualBox:

After applying the patch, you need to reconfigure VirtualBox to make sure it recognizes the changes:

/sbin/vboxconfig

Post-Solution Tips:

Have Fun! Now that you've resolved the issue, your VMs should start as expected. Dive back into your virtual environment and continue your work or play.

Stay Updated: Keep your system and VirtualBox updated to avoid similar issues in the future. Developers regularly release patches and updates to address known bugs and compatibility issues.
