Incorrect and failing boot in Virtualbox. Causes OS to freeze.


Ubuntu 9.04, VirtualBox. 2GB ram, 3Ghz Hyperthreaded Processor.
When booting the ISO in VBox, I'll first get a error from VBoxI had to enable PAE/NX. This is not a problem, expect that VBox couses total cpu consumpsion, freezing the desktop, and causing me to reboot the pc using the reset button.
After fixing PAE/NX, same thing, I booted the VM giging it the lowest priority possible, to let it not freeze my desk again. Ok, fine, everything worked, untill this message showed up. There my session ended with Singularity.
BL: Unrecognized kill action 0xFFFFFFFF!
BL Halt! blsingularity.cpp(720)

Hi Alex,

I have followed all the instructions from #3394 and This is a Windows 7 x64 host machine, running Virtualbox.

I am still seeing the error:

BL: Unrecognized kill action 0xFFFFFFFF!
BL Halt! blsingularity.cpp(720)

Has anyone been able to get Singularity working in Virtualbox? Virtual PC is no longer available for Windows 8, and I hope there will be a way to continue running Singularity in the future. Any help is appreciated.

Kind regards,

In Windows 8 you have Hyper-V, but also have the same problem.
