After upgrading to Plasma 6, I can not longer use Virtualbox. I'm starting plsama via startx, which may or may not be part of the problem. I have attached VBoxSVC.log which is the only log created, no vm log is created before crash. I find it a bit interesting that none of the /dev/vboxdrv* devices have group permissions for vboxusers, not sure if that's related. Reproducible: Always Steps to Reproduce: 1. Upgrade to Plasma 6 2. Make sure you are using KVM in virutalbox 3. Try to start any virtual machine Actual Results: Virtualbox crashes with an obscure error and outputs 'Failed to open "/dev/vboxdrvu", errno=13, rc=VERR_VM_DRIVER_NOT_ACCESSIBLE' in the logs. Expected Results: I expect Virutalbox to continue working.

I just downgraded to 6.1, and things are back to functioning normally. emerge -av1 =app-emulation/virtualbox-6.1.50-r3 =app-emulation/virtualbox-additions-6.1.50 =app-emulation/virtualbox-extpack-oracle-6.1.50 =app-emulation/virtualbox-modules-6.1.50-r2
7.0.20 also works well, so this problem is isolated to the latest 7.1.0 release.
I haven't seen any related ticket or discussion on their forum. It should have access, VirtualBoxVM is installed setuid root. Can you check the correct modules are loaded?
The correct modules were indeed loaded. I am using 6.11.0 but I don't think there would be a regression between 7.0 and 7.1 for the new kernel. Let me know if you think of anything else to check. I am at a loss on this one.
Please post the output of `emerge --info virtualbox`
Created attachment 905120 [details] emerge-info.txt I just tested 7.1.2 and that has the same problem. I was comparing the VBoxSVC.log between 7.1.2 and 7.0.20 and noticed that both are reporting "Failed to open "/dev/vboxdrvu", errno=13, rc=VERR_VM_DRIVER_NOT_ACCESSIBLE" but only 7.1.2 has the following two errors: 00:00:00.008819 main rtldrNativeLoad: dlopen('/usr/lib64/virtualbox/libpthread.so', RTLD_NOW | RTLD_LOCAL) failed: /usr/lib64/virtualbox/libpthread.so: cannot open shared object file: No such file or directory 00:00:00.008834 main rtldrNativeLoad: dlopen('/usr/lib64/virtualbox/libdl.so', RTLD_NOW | RTLD_LOCAL) failed: /usr/lib64/virtualbox/libdl.so: cannot open shared object file: No such file or directory
I tried to build it with your CFLAGS and USE flags, still works for me with both KVM and Legacy. I looked in the logs, that error message is a red herring, I also have it: 00:00:01.541690 DCon04 Failed to open "/dev/vboxdrvu", errno=13, rc=VERR_VM_DRIVER_NOT_ACCESSIBLE To find out where yout virtualbox is crashing, you need to compile it with debug symbols (-ggdb3), with FEATURES=-nostrip or splitdebug, then run it as root, because setuid binaries do not dump core. Set `ulimit -c unlimited`, then run it directly: /usr/lib64/virtualbox/VirtualBoxVM --startvm yourvmname After it crashes check it dumped core, and try to obtain a backtrace with gdb /usr/lib64/virtualbox/VirtualBoxVM core and open a ticket upstream with the backtrace. What you can also test is if something coming from your "-march=native" breaks the build. Try to compile it with -march=x86-64, see if that fixes the issue.

I wonder what it's mismatched with. No random copy in /usr/local or something?

Yes, looks like a botched installation. And that SIGTRAP is suspicious. I can't figure out what's wrong.
I would depclean all virtualbox packages and then scan your system for anything referencing it.
Dep cleaned, verified everything was gone. Only installed virtualbox and the modules on 6.11.3 and now I get a different segfault in libc.

(In reply to Alex Barker from comment #9) > > Failed to initialize the support library, rc=VERR_VM_DRIVER_VERSION_MISMATCH! > You get VERR_VM_DRIVER_VERSION_MISMATCH when the kernel modules do not match. It is a different message from VERR_VM_DRIVER_NOT_ACCESSIBLE and it is fixable with a simple reboot. I usually run this after updating: rmmod vboxnetadp; rmmod vboxnetflt; rmmod vboxdrv; modprobe vboxdrv; modprobe vboxnetflt; modprobe vboxnetadp As for VERR_VM_DRIVER_NOT_ACCESSIBLE, I don't know what could cause it other than a permission problem, which should happen as long as you are in the vboxusers, because VirtualBoxVM is setuid root. If you get this crash consistently, you should update your upstream ticket, because what you uploaded there is the run with the mismatching kernel modules. Also, do you also get the crash if you run `VirtualBoxHeadless --startvm yourvmname` instead of `VirtualBoxVM`? Sometimes it writes more info this way.
Also please check the bug linked by Sam, maybe it's the same issue.
Same problem, different paths: ln -s /lib64/libdl.so.2 /usr/lib64/virtualbox/libdl.so ln -s /lib64/libpthread.so.0 /usr/lib64/virtualbox/libpthread.so

Definitely, the synlinks resolved the issue. I am leaving the computer for 7 days. If you figure out what caused this feel free to close. If you need me to test/check stuff, I can respond when I am back.
