   virtualbox vcvtsi2sd illegal instruction   
   09 Aug 20 14:08:05   
   
   Hi!   
      
   When I use   
      
   mov       rax,123456789012   
   vcvtsi2sd xmm0,xmm0,rax   
      
   on the host system, and step through it in a debugger it works well,   
   but when I do the same thing in virtualbox on a linux guest I get an   
   illegal instruction.   
      
   I thought the virtualbox code runs natively on the host cpu, so the   
   instruction set should be the same.   
      
   What's going on here?
