Error when installing Kali using qemu on Linux Mint

I installed qemu and kvm. Created an image using…

sudo qemu-img create -f qcow2 debian.img 15G 

…and when tried to load the iso file…

sudo kvm -hda debian.img kali-linux.iso -m 2048 -net nic -net user -soundhw all 

then this error shows up…

qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000001H:EDX.syscall [bit 11] qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000001H:EDX.lm [bit 29] qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000001H:ECX.svm [bit 2] 

What can I do now?
