It's like a really slow when I enter command, when I enter l When I knock on a carriage return, I can feel a bit slow. As long as the command has a response, such as ls, ping, will block this page, I only closed the browser, start again. But I am in the other OpenStack vnc is normal, I ask where is the config of the problem? Help me find the problem

When I use the ping command, then use ctrl + c, but the page is not responding.

When I close the page, re-come in, then the current ping is over, indicating that I ctrl + c work, but before the page blocked

Is there any problem with my configuration parameters? Help me find the problem

Your links don't work (I use Firefox).

I would test access to the console without OpenStack. E.g. in case your hypervisor is libvirt, run virsh vncdisplay and connect to that display. You may have to adjust the listening address (virsh edit, then the line <graphics type='vnc'...).

When trying to access your links with Internet Explorer, I get "This website requires you to log in".

I changed the picture link address, you can open now.

My libvirt is the same as what you said.

I can open vnc by vncviewer, running very smooth。 only in novnc of horizon is block when entering a command.

I noticed the same thing on my builds (so I switched to spice console). However,I don't recall if I only had the problem with Chrome or all browsers.

Let's summarize:

  • browser->novncproxy->VNCserver in qemu: Slow.
  • vncviewer->VNCserver in qemu: No problem

The problem could be in the browser or novncproxy or their connection. I would first try a few browser alternatives. Not sure how to tackle a novncproxy problem.
