Re: [Qemu-devel] Disk I/O in QEMU

[Le Tan]

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!

But you didn't specify vnc as display in your command line?

Try specify "-vnc :0" and connect with "vncviewer :0".
