kernel panic in host with kernel 3.16.x and linux guest

[Potomac]

where is the non-sense ?

in archlinux we have 2 methods for loading the kernel modules ( vboxdrv, vboxnetadp and vboxnetflt ) :

1) load manually the kernel modules with the modprobe command before running virtualbox

2) or set them in a /etc/modules-load.d/virtualbox.conf file in order to load them automatically at each boot

I prefer to use the manual method because I don't use everyday virtualbox

I don't know, what arch do, but in debian modprobe vboxdrv is enougth, because the other modules are loaded by vboxdrv.

This bug also appears with Windows 7 x64 guest. I found 2 cases when it happens:
1. right after Windows starts (before login).
2. when installing a new OS on the first stage (just after selecting target disk, etc.)

(sorry for my English)

[Potomac]

very interresting, so all type of guest can have this bug

[Potomac]

in the french forum of archlinux we found that moving the virtual machine to "/home" instead of using a fuse filesystem ( like an usb harddrive NTFS ) can solve the bug,

so it's seems that if the virtual machine is located in a partition mounted like a fuse filesystem ( ntfs partition for example ) then a freeze or a kernel panic can occur with kernel 3.16.x,

and more important : the bug occurs also with the official binary of virtualbox

Hi, the same here, with the kernel 3.16.1 (Archinux kDE desktop). I have a doubt the problem is the kernel, who has built the package for archlinux or a bug in virtualbox (3.14) that not working well with the kernel version 3.16.1.

Thanks

@Malus : where is located your virtual machine ?

in a ntfs partition ?

or an ext4 partition ?

it seems that the bug occurs when the virtual machine ( the vdi file ) is located on an ntfs partition ( or a fuse filesystem type ) and if a kernel 3.16.x is used

[Potomac]

ok,

so it's confirm that the bug occurs if the virtual machine is located on a ntfs partition and if a kernel 3.16.x is used,

I hope a solution will be found soon

[Malus]

I hope a solution will be found soon

I hope the next virtualbox-host-modules update fix the issue. Do you think @Potomac ?

Best Regards.

[Potomac]

I don't know, because the bug could be also in the virtualbox source code, and not only on virtualbox-host-modules,

the bug could be also on the ntfs-3g program or in the kernel 3.16.x

[Potomac]

you can to try to build a package "kernel 3.17rc1-1" :

https://aur.archlinux.org/packages/linux-mainline/

it's easy with "makepkg" in archlinux, maybe they have already fixed the bug in 3.17.x branch mainline

[Potomac]

I can also reproduce the bug by using "qemu/kvm" instead of virtualbox,

so there is a real problem in the kernel 3.16 related to "fuse filesystem", I created a bugreport here :

https://bugzilla.kernel.org/show_bug.cgi?id=82951

[thetazerlaser]

I'm having this problem on a Gentoo host with kernel 3.16 and vbox 4.3.18

[Potomac]

the solution is to use kernel 3.17, with this version of the kernel the bug is gone :
