I am sorry I didn't give the complete command I have executed. It is like this: qemu-system-x86_64 -m 1024 -smp 2 -hda /home/tanle/study/new.img -nographic -vnc 192.168.146.118:2 -enable-kvm If I delete the "-enable-kvm", it is ok and the system can boot up (just slow). But with "-enable-kvm", the vnc viewer is just black, displaying nothing. So did I miss any options? Or there is something else wrong? Thanks!
