Failed to boot chromiumOS with kvm, error is could not set up host forwarding rule

[Xing]

Hi, I followed this https://www.chromium.org/chromium-os/how-tos-and-troubleshooting/running-chromeos-image-under-virtual-machines to setup chromiumOS with kvm.
When boot with ./bin/cros_start_vm, it prompts the following errors:

src/scripts$ sudo ./bin/cros_start_vm --image_path=../build/images/amd64-generic/latest/chromiumos_qemu_image.bin

BTW, I changed the sshd config files as below, and restart service ssh, the errors are the same.
:/etc/ssh$ diff sshd_config_back sshd_config

are you already running a VM w/that port forwarded ?

check dmesg to see if there's anything interesting.

Thanks.

It does have one kvm instance. After stop it, and restart, I didn't see any chromium OS UI appear. Do you have any hints about this?
BTW, I am trying to add format=raw to ./bin/cros_start_vm, but it seems not so straightforward.

do you mean you don't see a graphics window at all ?  or do you mean it comes up, but stays black, and the Chrome bootsplash/login window doesn't show up ?

It shows nothing.

[Xing]

I means don't see a graphics window at all

[Mike Frysinger]

don't run it under sudo.  our scripts take care of that.

Hi,

You need a VNC client to see the UI.

The log mentions 'VNC server running on '127.0.0.1;5901', can you try to connect your VNC client to 127.0.0.1:5901 ?

Nicolas.

 Thanks. Something is wrong with my preinstalled VNC viewer, with Remote Desktop Viewer, it works!

If you want to run it without having to VNC in, you can install qemu and kvm on your system natively and invoke it manually:

qemu-system-x86_64 -enable-kvm -m 2G -smp 4 -usb -usbdevice mouse -show-cursor

-vga cirrus -net nic,model=virtio -net user,hostfwd=tcp:127.0.0.1:9222-:22 -drive file=chromiumos/src/build/images/amd64-generic/latest/chromiumos_qemu_image.bin,index=0,media=disk,cache=unsafe

This worked the last time I tried it, which was admittedly a few months ago.
