Kernel update and virtualbox kernel modules blues

[hans]

Thanks. So how can I check whether the kernel-headers package is installed?
Using pamac searching for ‘kernel-headers’ shows none for the installed category in the All category only kernel-headers-musl with version 4.19.81 All (and 4 in the AUR). Is this the one to install? and remove the virtualbox-host-dkms vs 7.06?

On the running kernel 5.15. vbox is running OK. This must? mean that the required kernel modules are loaded (or else vbox would fail to run).

Tip

mhwd-kernel will automatically update a newly installed kernel with any modules currently used in your existing kernel . For example, if you were to update from kernel 4.14 to 4.19, mhwd-kernel would automatically update 4.19 with any and all modules present in 4.14. How about that!

So I am still confused!
