[Qemu-devel] Why got no response of vnc?

[Sam]

Hi all,

I'm starting vm using:

kvm]$ sudo /usr/local/bin/qemu-system-x86_64 -m 256 -hda test.qcow2 -cdrom
> CentOS-7-x86_64-DVD-1503-01.iso -boot d
> VNC server running on '127.0.0.1:5900'


then I start vnc client in another PC to connect 10.253.23.24:11800 and
10.253.23.24:5900, I got time out, why?
