Hi!
Seems that the latest virtualbox on host is not working at all.
So I suggest people who use virtualbox put this line into their /etc/pacman.conf:
IgnorePkg = virtualbox virtualbox-host-dkms
and possibly downgrade those packages to version 6.1.12-3.
Seems also that virtualbox guest is not affected, but I didn’t test this throughly.
I’ve just updated to these versions too. I haven’t rebooted yet though. 
Here reboot didn’t make a difference. Downgrading helped.
It’s preparation for Kernel 5.8, which should follow very soon.
So don’t forget to unignore when 5.8 hits the repos
Yup, looks like the patch for 5.8 breaks the driver for other kernels. 
(Or, at least for me, linux-ck-zen=5.7.15)
It’s an interesting patch - much larger than the one I used for my 5.8 and which also worked.
Probably more changes under the hood, and maybe with this one we do not need to patch the kernel.
Thanks for alerting us, I was just about hitting enter on yay 
I heavily depend on Virtualbox.
Interestingly enough, here, it does work with 5.7.12 and VBox 6.1.12-4 ???
Although I compiled VBox myself, it’s almost identical to Arch’s, only inclusion is a patch for i3 and disabled WebService.
Mine was broken as well. I had to downgrade to 6.1.10 version for it to work.
Shoot. I read this right after hitting y to update 
Thanks for the heads up, I’ll downgrade accordingly.
Not to blame on Virtual box, but try qemu instead with easy managing:

You also need the latest development build for the extensions and guest ISO.
I got nasty coredumps and bugs with the 6.1.2 release version:
kernel: VMSVGA FIFO[2383]: segfault at f8 ip 00007dda68f30279 sp 00007dd9959fec70 error 4 in libX11.so.6.3.0[7dda68f2e000+8a000]
Okay, gets worse… complete crash and reboot.
No entry in the journal.
However I suspect it’s the same issue I had a few days ago:
kernel: softirq: huh, entered softirq 7 SCHED 00000000e35fd30b with preempt_count 00000101, exited with 00110101?

I’ve got virtualbox 6.1.12-4 working now …
I’ve installed the following updates today:
virtualbox 6.1.12-4
virtualbox-ext-oracle 6.1.13.139853-1
virtualbox-host-modules-arch 6.1.12-8
virtualbox was broken when I first got the 6.1.12-4 update, then still broken when I got the host-modules-arch 6.1.12-8 install … but now that I have also updated to the ext-oracle 6.1.13.139853-1 package from AUR everything seems to be working again.
PS - no custom kernel builds or anything on my side. just running linux 5.7.12.arch1-1 from the repo
I also have virtual box up and running now with the latest update that just came through.
Edit: Not so sure it’s working though? Trying an install of Deepin and i think it’s froze up? 
I have tried a couple different install on v-box and it’s just freezing at 28%. So it’s still not working for me. 
v-box is chugging through some guest OS updates for me … so far so good …
virtualbox-host-modules-arch 6.1.12-8 fixed it …
I got the problem too. Temporarily switch to Neon to continue my work while waiting for the fix.
Downgrading for now also works. Possibly less drastic than switching OS.
