virtualbox.org

Hi,
i have VB on an WIn 10 host, Ubuntu as Guest, Virtualbox Additions installed, everything is fine (e.g shared folder, network, ..)
To save some disk space i would like to uninstall linux-headers. Is there any need to keep them for operating the vm, and still use all Additions (shared folder). I guess headers are just needed for installation and not for ops.
Thx

Best Regards

I would assume that you don't need the headers except for the compilation. But, if you upgrade your kernel or your Guest Additions (GAs), you're going to need them again. And if at that time, you don't have enough space to install the headers, your GAs might fail to work.

But I'm not a Linux expert, which is why I'm moving the thread to "Linux Guests" from "Windows Hosts", to get a second opinion...

It's Linux. You can do pretty much anything you want and know how to do. Headers (for the running kernel) are needed for compiling the kernel modules and yes you can remove them, but they are relatively a small package and if your disk space is so small that the header "weight" concerns you I would adjust the disk size to a larger state.
