Hi, when i try to launch VM in VirtualBox, the host itself completely freezes. Tried to reinstall VirtualBox, reinstall virtualbox-modules - nothing helped.
In VBoxSVC.log i can see an error:

Failed to open "/dev/vboxdrvu", errno=13, rc=VERR_VM_DRIVER_NOT_ACCESSIBLE

though it exists:
$ ls -l /dev/vboxdrvu
crw------- 1 root root 10, 122 Sep 1 18:34 /dev/vboxdrvu

and also module is loaded:
$ lsmod | grep vbox
vboxnetflt 36864 0
vboxnetadp 24576 0
vboxdrv 626688 2 vboxnetadp,vboxnetflt

Exactly same issue on 2 different machines. what can i check to try to debug the issue?

also checked - my user in vboxusers group

What is the output of
Code:

grep -r vbox /etc/udev/

it doesn't help, and after reboot it reverts back:
# ls -l /dev/vbox*
crw------- 1 root root 10, 123 Sep 8 10:00 /dev/vboxdrv
crw------- 1 root root 10, 122 Sep 8 10:00 /dev/vboxdrvu
crw------- 1 root root 10, 121 Sep 8 10:00 /dev/vboxnetctl


grep -r vbox /etc/udev/
returns nothing

Try
Code:

chmod 666  /dev/vbox*


There should have been udev rules created for these devices.I wonder why they weren't.
According to vbox ebuild
Quote:

if use udev; then
local udevdir="$(get_udevdir)"
local udev_file="VBoxCreateUSBNode.sh"
local rules_file="10-virtualbox.rules"

insinto ${udevdir}
doins ${udev_file}
fowners root:vboxusers ${udevdir}/${udev_file}
fperms 0750 ${udevdir}/${udev_file}

insinto ${udevdir}/rules.d
sed "s@%UDEVDIR%@${udevdir}@" "${FILESDIR}"/${rules_file} \
> "${T}"/${rules_file} || die
doins "${T}"/${rules_file}
fi

Are you not using udev?
Is there any init script vbox-related in /etc/init.d
?

# ls -l /etc/init.d/vbox*
-rwxr-xr-x 1 root root 1137 Sep 8 10:18 /etc/init.d/vboxinit-5.2.1
-rwxr-xr-x 1 root root 646 Sep 8 09:36 /etc/init.d/vboxwebsrv


firstly - i changed permissions and ownership:
crw-rw-rw- 1 root vboxusers 10, 123 Sep 10 08:38 /dev/vboxdrv
crw-rw-rw- 1 root vboxusers 10, 122 Sep 10 08:38 /dev/vboxdrvu
crw-rw-rw- 1 root vboxusers 10, 121 Sep 10 08:38 /dev/vboxnetctl


then - i started VirtualBox - i don't see anymore permissions related errors.
After creating some dummy VM (without any configuration - just create VM, without changing anything) - i see this in log:
ERROR [COM]: aRC=VBOX_E_INVALID_VM_STATE (0x80bb0002) aIID={300763af-5d6b-46e6-aa96-273eac15538a} aComponent={MachineWrap} aText={The machine is not mutable (state is PoweredOff)}, preserve=false aResultDetail=0
ERROR [COM]: aRC=VBOX_E_OBJECT_NOT_FOUND (0x80bb0001) aIID={5bfd8965-b81b-469f-8649-f717ce97a5d5} aComponent={NvramStoreWrap} aText={The UEFI NVRAM file is not existing for this machine.}, preserve=false aResultDetail=0

The moment i started this VM - the whole host freezes, and i had to hard reset it. After reboot - all permissions reverted back, and no logs were added to VBoxSVC.log

Hello leonchik1976,

have you found a solution for this problem? I have this problem, too, but don't know the reason for it. For many years VirtualBox worked without any problem.

Thanks and best regards,
Manfred

Does the kernel panic to cause this freeze? Is there anything written to the kernel's console? Beware that a sufficiently hard freeze may kill syslog before it can write to a file, so you need to read the data off the console.

the moment you start VM (any VM - just create any VM - even without changing it's parameter) - the system freezes completely.
same issue on 3 different intel machines

Can you start a VM from the VT1 text console ? (CTL-ALT-F1)
If it's a kernel panic it should vomit a dying message on the console.

When starting a virtual machine, the PC freezes immediately. I've started "dmesg -w" in a terminal and took a picture with the smartphone and extracted the text with Google Lens. These five lines are the last I saw after starting the VM:

Code:
[289.283991] SUPROGipMap: fGetGipCpu=0x1b
[290.947884] vboxdrv: 00000000905680cb VMMRO.ro

Try moving your VM to another internal drive. I encountered a similar issue, running a VirtualBox Win 11 VM on my Gentoo host PC. Win 11 runs fine, but Gentoo processes hang. I have to hold the power button to turn off my PC. My solution was moving the VirtualBox VM folder from my root partition (containing /home) to a second internal drive.

Note: This solution did not fix the same issue running a VMware Workstation Win 11 VM.

Same setup as leonchik1976, no problems at all here.

Note udevdir:
Code:

/lib/udev/rules.d/10-virtualbox.rules


I found this https://bugs.gentoo.org/768297 and this https://forums.gentoo.org/viewtopic-p-8690935.html?sid=99d68bb6998eaf888e4056efb93b5471. Have you checked ownership of /dev (here: 755 root:root)?

What about the VBox.log file as per https://www.virtualbox.org/manual/ch12.html?
