[gentoo-user] Virtualbox-5.0.0 [wow!]

[gentoo-user] Virtualbox-5.0.0 [wow!]

[walt]

Even while slogging through my painful and ongoing update of perl and
friends, I managed to install Virtualbox-5.0.0 and its guest-additions.
(Apparently these two packages don't depend on perl at build-time.)

I fired up my vbox gentoo guest machine and, of course, I tried to
install the 5.0.0 guest additions kernel modules.

I got an error message about usb support in the guest kernel, so I
disabled guest usb support (temporarily) with the vbox gui, tried again
and the guest kernel modules installed with amazing speed.

I'd like to know if anyone else is seeing spectacular speed performance
with vbox-5.0.0.

No noticeable performance improvement for me using hardware virtualization.

The USB issue is because it no longer pulls the extension pack or additions 
packages as a dependency so you need to add them to your world file. It also 
fails to compile for me with doc or sdk flags.

Thanks, I will.

A comment on nerd humor:  while using vbox-5.0.0 my eye was drawn to a
little black spot in the vbox main window, and I wondered if it was a
dirt speck on my monitor screen.

I put on my reading glasses to take a closer look.  It turned out to be
a new icon for the "Clone selected virtual machine" button in the form
of a black-faced sheep.

I conclude that this must be a sly reference to Dolly the Sheep, the
first 'higher' animal to be cloned successfully, except that Dolly
didn't have a black face, according to this:

Also here the paravirtualization additions are not having any
noticeable effect on performance (checked with the Windows Experience
Index on W8).

What I am seeing though are various regressions:
- fullscreen no longer goes fullscreen (with fluxbox doesn't cover
  the slit and hides behind toolbar)
- weird sound/video problems with youtube (accelerated video, constant
  popping noises)
- doesn't work at all since I updated to the 4.2.0-rc2 kernel

I had great expectations but so far I'm disappointed.

Fullscreen works fine on kde and openbox.
I've had the sound problem with earlier versions and pulseaudio. IIRC I fixed 
it by tuning PA fragment size.
And it works fine with 4.2.0-rc2 for me. Did  you remember to re-emerge app-
emulation/virtualbox-modules (after setting the /usr/src/linux symlink to the 
new kernel source)?

Works fine on fluxbox as will, but only with <=virtualbox-4.3.30 (I'm 
using the binary package btw).

I'll check that but I have a feeling that the popping in the audio is 
connected to the accelerated video. But as I said, pulseaudio normally 
works fine, and everything works with the previous virtualbox version.

Yes and yes. However now I'm experiencing lockups whenever I start a VM in 
virtualbox 5 when running kernel 4.2.0-rc2, so I can't even check anything 
else. For the time being I'm back on 4.1.2; let me see again if I can make 
it work here.

And Btw. I'm not talking about starting a fresh vm here, I have an 
existing one that I'm trying to migrate.

So it seems I wasn't the only one with the problem on 4.2 (linux):

https://forums.virtualbox.org/viewtopic.php?f=7&t=68883

It has been acknowledged and fixed and will be released in a future
version.

I'll have to wait until then for a second impression of Virtualbox 5.0.
