Here is my update to the closed/obsolete ticket: I'm having this same problem. Just started after applying a kernel patch requiring a reboot. So, I tried to find updates/patches and ended up pulling down the latest RPM for SUSE 13.2 64bit. Here is what I get when I attempt to fire up my W7 Home Premium under VBox (was a working image prior to the kernel patch). Failed to open a session for the virtual machine W7 Home Premium. The VM session was aborted.
