Tails 2.7 has virtualbox-guest-{utils,x11} installed, but is missing virtualbox-guest-dmks
and thus does not longer has support for shared folders in virtualbox.

History

#1 Updated by obfusk almost 3 years ago

  • installing it manually is problematic with a 64-bit kernel and 32-bit userland.
  • booting in 32-bit mode seems to cause some kind of error (I can't read the screen fast enough to see the details) regarding vbox_ something during boot; this seems to cause the "waiting for plymouth" to hang and thus the "welcome screen" never appears.
  • booting in 32-bit mode using failsafe mode seems to work.
  • now the virtualbox-guest-utils service doesn't start (call trace indicates problem with modprobe).
  • it seems that the 32-bit kernel does have the kernel modules installed, whereas the 64-bit one does not.
  • the vboxvideo kernel module does not get loaded and a modprobe attempt results in a call trace.
  • mount -t vboxsf ... results in a OOPS for a kernel null pointer dereference...

Booting (not failsafe) with modprobe.blacklist=vboxvideo works w/o errors; mount -t vboxsf ... then works too.

FYI: I'm using virtualbox 5.1.8-dfsg-7 (debian sid).

NB: I haven't tested shared clipboard, resizing the display seems to work fine.

And yes, the title of this bug report is no longer (entirely) correct.

#8 Updated by intrigeri almost 3 years ago

  • Status changed from New to Rejected

As our doc says, at the moment we only support running Tails in 32-bit VirtualBox VMs, since the 32-bit guest additions don't play well with the 64-bit kernel modules... and even if they did, building the 64-bit version is a pain on Tails 2.x due to multiarch. Tails 3.x will be 64-bit only and should have none of these problems. So I'm rejecting this ticket as it's about an unsupported use case.

#9 Updated by obfusk almost 3 years ago

I guess it wasn't entirely clear from my description that most of my later comments related to problems w/ a 32-bit VM.
I'm moving this over to #11965.
