I guess we're going to make a note in the advisory or somewhere about the fact that some users may need to remove /etc/X11/xorg.conf, or at least remove the ModeLine lines from it for X to work.  Yet another upstream X-related regression that we can't do much about.

Otherwise, it's working just fine on Mageia 5 i586 guest and host.  I'll test x86_64 at work.

Whiteboard: (none) => MGA5-32-OK

Mageia 5 x86_64 host tested fine with Windows 7, Solaris 10, Solaris 11, PC-BSD, Fedora, Ubuntu, OpenSuSE, and Debian guests.

I'm having some issues with a Mageia 5 i586 guest on Mageia 5 x86_64 host.

The kernel modules for the guest are loaded, but /var/log/Xorg.0.log shows "vboxvideo: kernel driver found, not loading."

So then X fails to start.  If you remove xorg.conf and install x11-driver-video-modesetting, it will use that and work.

Was there a kernel update in the guest?
Does it work better if you update the guest additions and/or the x11-driver-video-vboxvideo package?

There's no harm in releasing this one though, since this VM has the same problem now with 5.0.20 guest additions too.  I would like to get to the bottom of this issue if you can help debug it.

I have updated the guest to kernel 4.4.13 to match the prebuilt kmod for vboxadditions that's in there too.  There's no apparent reason it shouldn't work.

Updated in a MGA5 64-bit host, updated extension pack, started and added guest additions and X11 video driver to a 64-bit Mageia 5 guest, a 32-bit Mageia 5 guest, and a Windows XP guest. (Be aware that the Mageia guests had already been updated to kernel 4.4.13 for a previous test.)

No problems noted.

Now my VM at home is having the same problem :o(

I see this has been rebuilt as 1.1.mga5.  I upgraded my 64-bit host and 32-bit VM at work and there's no change, still no X.

Now 5.0.24 is out:
https://www.virtualbox.org/wiki/Changelog

Unfortunately, they reverted the fix for the networking performance :o(

Tested 5.0.24, Comment 3 is unfortunately still valid.

I'll test it with other guests soon, and suspect it'll still work fine.

Summary: update request: virtualbox 5.0.22 maintenance release => update request: virtualbox 5.0.24 maintenance release

Indeed all other OSs work fine as guests.

Went to install this update, saw files for kernel 4.4.13-2 in the repo, so I updated all at the same time.

Everything seemed to work. The update seemed to take a very long time, but then at least one set of vbox kernel modules was being built, also modules built for the existing nvidia 340 driver. After downloading and installing the vbox extpack through the Vbox "check for updates," Mageia 32-bit and 64-bit guests were good to go, including after updating the vbox guest additions and kernel on each.

Windows XP guest also functioning, after the usual Windows XP folderol.

Working perfectly fine at home with my Mageia 5 i586 host and guest.

Should we push this one now, or go for the just released virtualbox 5.1 that has working apic, x2apic and io-apic implementations giving better performance...

if we push this one now, I will still push the new 5.1 series after for tests so it will match what we will have in mga6

Push it.  It works fine in most cases and is no worse that 5.0.20.  Then we can start testing 5.1.
