VurtualBox. Module vboxguest builds, won't install

business_kid · 01-14-2017, 09:01 AM

On 14.2, with virtualbox-5.1.12 I'm trying to do a tidy up before instaslling a vm. I've installed the Extension pack, and Guest additions, but I'm stopped by this error

Code:

vboxadd.sh: failed: modprobe vboxguest failed.

The modules build OK. They also appear in modules.dep. But this is what happens when you try installing them.

Code:

bash-4.3$ ls -lh /lib/modules/{4.4.14,4.4.14-dec}/misc/vboxguest.ko
-rw-r--r-- 1 root root 352K Jan 14 11:33 /lib/modules/4.4.14-dec/misc/vboxguest.ko
-rw-r--r-- 1 root root 352K Jan 14 11:52 /lib/modules/4.4.14/misc/vboxguest.ko
bash-4.3$ sudo modprobe vboxguest.ko
modprobe: FATAL: Module vboxguest.ko not found in directory /lib/modules/4.4.14

Looking for errors, I get these relevant ones

Code:

bash-4.3$ sudo depmod -eF /boot/System.map-huge-4.4.14
depmod: WARNING: /lib/modules/4.4.14/misc/vboxvideo.ko needs unknown symbol pv_irq_ops

I presume I'm missing something(s), but what? I can't seem to find a recent mention of it.

EDIT: Those symbols (alloc_pages_current, pv_mmu_ops, pv_irq_ops, & pv_lock_ops) seem to be all over the kernel .o files, plentiful in /lib/modules/, but in neither libs or headers anywhere :-o.

Quick Q for you.

What kernel version are you running ?

Code:

uname -r

4.4.14 has been updated a couple ( ? a few ? ) times.

The latest Official Slackware 14.2 kernel is 4.4.38 ...

The huge 4.4.14 is the original from the 14.2 iso. I rebuilt the 4.4.14 source with my own config, that's the 4.4.14-dec kernel in the post below. I use my own kernel mainly, just have the 'huge' for the evil day that something breaks.

I gather the 4.4.x kernels seem all right, but I've seen a few posts where 4.8.x kernels break things for people. What happened 4.5.x - 4.7.x? I have done zero reading on kernels recently - I unfortunately have bigger fish to fry. What source version would you recommend?

Right. I grabbed the source package for 4.4.38 & built my config; that saves it looking for hardware I haven't got. Depmod stopped complaining about vboxguest, but vboxadd still puked on it. Interestingly, I get 6 modules in 4.4.38, but only 3 in the other kernels. Dmesg says

Code:

  9.576067] udevd[266]: NAME="%k" is ignored, because it breaks kernel supplied names, please remove it from /lib/udev/rules.d/65-kvm.rules:1

and of course depmod is still unhappy

I did put in a kvm group to humour it. I suppose I had better add my username to it. All those 'ttm*' symbols are in the kernel video stuff by the way.

/goes off to reinstall virtualbox, for want of a better idea.
