A little matter I would like to bring to your attention is our wiki page for Virtualbox can produce a small surprise. The scenario is that you download Sabayon 8 version, install it and than decide to install Virtualbox and Virtualbox pulls a lot of stuff including a new kernel of 3.3. Sabayon 8 iso comes with kernel 3.2 so when you go and install Virtualbox you are indirectly invoking a kernel upgrade. So the question is how to install Virtualbox.
Well, here is what I would do. We keep our packages updated so we might as well upgrade the kernel also, but instead I would do it in a bit of different order of just doing equo install virtualbox-bin, I’d start with kernel-switcher.
We can use equo search linux-sabayon to see what the latest kernel is. And in my case it shows sys-kernel/linux-sabayon-3.3-r2 is the latest kernel. To see what your current kernel version is, simply run uname -r.
So now we can upgrade the kernel with:
kernel-switcher switch sys-kernel/linux-sabayon-3.3-r2
This will than upgrade the kernel and all the needed modules and add the entry to your grub. Now at this point and time I would reboot and boot into the new kernel. Once rebooted I would than:
equo install virtualbox-bin
The modules should pull, but if not:
equo install virtualbox-modules#`uname -r`
usermod -a -G vboxusers YOUR_USER_NAME
Now go ahead and log out and than log back in so the changes can be applied.
To get virtualbox modules to load automatically:
# nano /etc/conf.d/modules
add to it:
modules="vboxdrv vboxnetflt vboxnetadp"
then save and exit, reboot.
Once you have Virtualbox installed you won’t have to worry about pulling kernels, it’s just that initial install and if there is a new kernel available scenario. If one had downloaded and install Sabayon 8 and installed Virtualbox before kernel 3.3 came out, one would never of had to fuss with a different kernel.
The only thing we are really doing that the wiki doesn’t cover is switching the kernel first. Why do I recommend using kernel-switcher vs just installing it all with equo install virtualbox-bin? The main thing is, you’re changing kernels so I want to keep that process simple and smooth vs pulling it and doing a bunch of updates along side it. In theory both methods should work, I just want to take the extra step and make sure it goes right.
