I have ruled out hardware issues - we have enough CPU, RAM and HDD to run all the services we need and the hardware is working fine.Īs an experiment, I stopped all of the VirtualBox machines and disabled all VirtualBox related services which were starting at boot and rebooted. There are no logs and nor indication of what might be causing this. VirtualBox Inside Docker This project should allow any user to successfully install VirtualBox inside a docker container allowing you to intall any OS virtually inside a virtual containers Sounds cool right Usage To use this image, you must install and load the Virtualbox driver on the host, and mount /dev/vboxdrv to the container. At first, everything was working flawlessly, but once time went by, the machine started freezing randomly. If you’re following along hopefully you don’t encounter the same issue. This is why we have kept a 1 virtual machine running as well. Docker was now running successfully within a VirtualBox VM, achieving my goal, even though it wasn’t the greatest solution. Unfortunately we can't fully migrate to Docker just yet.
Recently we decided to migrate our Linux based VirtualBox machines to Docker. (after all services have been started there is ~19GB free RAM left)įor a long time we have been using VirtualBox to create virtual machines with various Linux distributions so we can test our product. The machine has 12 cores & 32GB ram and has hyper threading enabled.I'm currently having issues with a server which randomly freezes.
