current error log suggests there is some issue with the qemu setup. Did you launch the container with --privileged flag? we need it to speed up qemu.
and aslo can you plz go to /kheap/exploit_env/CVEs/CVE-2010-2959/, run ./startvm there, and post the result, which will provide more detailed error output.
