I have an Ubuntu box installed over VirtualBox with Windows 7 as host. I installed guest additions in it and was working perfectly as expected.

Suddenly, one day VirtualBox complained that guest additions are not installed (possibly after an upgrade). I had to reinstall guest additions all the way again.

Is this because of kernel upgrades from Ubuntu? A new kernel needs a reinstall of guest addition?

No, generally it doesn't require. dkms takes care of the upgradation.

Please have a look here - How do I keep guest additions working in virtual box after updates?

However, some users report even after dkms installation the problem remains.If it is happening with you, I would like to point to the below answer.

First uninstall using sudo /opt/[VboxAddonsFolder]/uninstall.sh Then follow https://askubuntu.com/a/99479/35775

  • If this is happening with me, do I have to uninstall and reinstall guest additions every time a kernel upgrade happens? – Vineet Menon Nov 19 '13 at 05:30
  • First try the solution provided in the answer & the links. By following those steps, with kernel upgrade the installation should be done automatically. If those are not working, yes you have to do manually & it would be a bug too. – Web-E Nov 19 '13 at 07:49
