this is a known problem, since the vm image is not officially supported it
was kind of a low priority and I did not have time to fix it yet.

You can try to remove /home/luz/Code/digitalSTROM/dss-oe/angstrom-production-build-eglibc/deploy/images/qemux86/dss11-production-image-1.3.0-qemux86.tar.bz2
and bitbake dss11-vm-image again (without cleaning), in most cases it works
then.

As an alternative (if you need production), take one of the images here:
http://feedback.aizo.com/feeds/dss11-production-eglibc/images/qemux86/

And then simply do a regular system update via the web UI in order to get
the latest version. Again, nothing guaranteed since the VM stuff is
unofficial and thus untested, but even if you run into some troubles it will
most likely be possible to fix them on the console.

I need to change the way how those live images are generated, I think it's
done differently these times in OE, while I still use an older method.

Kind regards,
Sergey
