You can add individual host cpu features by using '-cpu 
qemu64,+feature', where feature is taken from the host /proc/cpuinfo.  
Do you know which cpu features the program can take advantage of?

Also please try replacing the constant 0x0007040600070406ULL in 
kernel/x86/svm.c with 0x0606060606060606ULL and see what happens (don't 
forget to reload the modules).

signature is too narrow to contain.
