Virtualbox question

Do VM's automatically get the benefit of Virtualbox updates, or do VM's have to be (partially) re-installed?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There should be no impact for your VM's, definitely no (partial) re-install.
If your not sure you can always backup the VM files...

In principle you could even uninstall Virtualbox and re-install completely, without impacting the VM's

Yes, but say VB introduces improvements to or even adds virtual hardware. Does anything need to be done in the VM to take advantage of that? Some parts of some Guest OS's do not work at present, for instance like graphics acceleration. VB is working on some of these to make them functional.
You need to manually install the VirtualBox extensions whenever there are updates. You also have to get the new extensions via VirtualBox to VirtualBox yourself.

Many Linux distro's include the VirtualBox extensions in their repositories, so if you installed them via the repositories in the first place, they will get updated whenever they get available and you run the Distro's package manager.

Yes, like rindi said... You'll need to update the extensions whenever there's an update to take advantage of them ... But it's not that much work, though it can interrupt your network for a short time when you update.

So provided I update VB and install the extensions, those things that don't work in VM's will start working on their own if a fix has been developed?
Sometimes, if there is really something new that was added, you may have to change the settings in the VM's settings so you can use them. But if they are just improvements those will just be added.
