I can't find a precise answer on whether it's possible to use plymouth splash screens during systems booting inside VirtualBox. There's quite a number of hits when looking for answer on google, but nothing really explaining... just mentions of "this won't work with virtualbox" or likes, nothing more elaborate I could spot. The best I could get is a "three dots" splash screen, but nothing really fancy, with either of the different themes, I've tested :-/ I'm testing this on a Debian testing/jessie VM, with standard kernel. Is there a particular incompatibility between plymouth and the VirtualBox emulated graphics card ? Many thanks in advance.

The kernel modesettng is not supported, so to get a graphical-capable console you need to specify a video mode. This seems a little messy to me, but this fix should do the trick (should be the same on Debian): http://www.randomlinuxstuff.tk/2013/05/fix-ubuntu-boot-screen-after-installing.html You shouldn't need to specify the video mode, and *"GRUB_GFXPAYLOAD_LINUX=auto"* should work as well, though. Hope it helps.

Thanks for you help. Still, I think I need some clarification, being a bit naive in terms of KMS, DRM and stuff.

Cause the vboxvideo and drm drivers are loaded, and I can provide the kernel with vga=xxx parameters which change the size and resolution of the virtualbox window displaying the console and the kernel messages. > This seems a little messy to me, but this fix should do the trick (should > be the same on Debian): > http://www.randomlinuxstuff.tk/2013/05/fix-ubuntu-boot-screen-after-installing.html > > You shouldn't need to specify the video mode, and > *"GRUB_GFXPAYLOAD_LINUX=auto"* should work as well, though. > I'm not sure I understand the difference between providing the kernel with vga=xxx args or this GRUB_GFXPAYLOAD_LINUX Also, it is not very clear what the FRAMEBUFFER=y" in /etc/initramfs-tools/conf.d/splash is supposed to do... and maybe Debian and Ubuntu are different on this :-/ Also GRUB_TERMINAL=console may be something that interferes with the rest of the options ? Maybe I don't understand exactly the requirements of plymouth... The problems with such quick howtos is that it's just not documented to explain what each step is supposed to do, and in case things don't work, you don't have hints on possible sources of failures. Sorry, I'm probably just too much a newbie in these matters, but if you can explain in more details what it tries to do WRT to drm, and how I could get hints on whether its a limitation where patching is needed or just a situation configuration can solve ? Thanks in advance.
