Yocto in Virtualbox

Hi,
I have build x86 qemu image using "bitbake -k core-image-sato" following the
instructions given at
http://www.yoctoproject.org/docs/1.1/yocto-project-qs/yocto-project-qs.html
I'm running Ubuntu 11.10 in VirtualBox 4.1.6.
When I run qemu, qemu starts apparently fine, but the qemu window stays
black. So I'm suspecting that either it does not work in Virtualbox or I may
have tochange some settings in qemu (e.g. -vga vmware).
runqemu qemux86

So, what is the problem?

I would try one of the pre-built images to isolate the problem between running inside virtualbox and your build.

This would be much quicker to test than my "export to VMWare Player"
suggestion. I'd definitely try this first.

FYI. have done some further tests with the prebuilt binaries and
toolchain (yocto-eglibc-i686-i586-toolchain-gmae-1.0.tar.bz2,
bzImage-2.6.37-qemux86-1.0.bin and
yocto-image-minimal-dev-qemux86-1.0.rootfs.ext3).

With Ubuntu 11.10 (Virtual Box), it fails with the same black screen.
With Debian Squeeze 6.0.3 (inside Virtual Box), it works fine.

PS: For Ubuntu, poky-qemu script to pass libGL detection.

Thank you for reporting this, I have filed the following bug to track
this issue:

http://bugzilla.pokylinux.org/show_bug.cgi?id=1971

Are you using the default user interface (Unity) in your Ubuntu setup?

Yes, I'm using the Unity user interface.

Just one detail. By mistake, yesterday I used Yocto 1.0 toolchain and
pre-built binaries. I've tried again with with Yocto 1.1 and I did not
need to change any script, but the black screen issue still occurs.

Have you installed the Virtualbox guest additions within your VM?

Fwiw I've not run into any issues doing this with a Fedora 14 and Fedora
16 VM (other than the builds themselves being dog slow). I make sure to
install the guest additions in all my VMs.

Thanks Scott. Yes, I have Virtual Box guest additions installed. My
host is running Windows XP btw. And yes it was slow...the build for
core-image-minimal took around 36 hours...
I found a link with a Virtual Box issue
(https://wiki.yoctoproject.org/wiki/Build_Appliance_Design), but it seem
related to the build itself rather than an issue while running qemu.
