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).
