##### SUMMARY
<!-- Explain the problem/feature briefly -->
With Ubuntu 20.04(KVM)+ACS 4.15, we noticed
- Access to Windows guests via NoVNC console is extremely laggy, barely to use. Even compared to the original
- Access to Linux guests via NOVNC consoles however, looks pretty smooth, no any issue
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.

I deployed Windows 10 VM using 2 cores, 2 GHz and 4 GB virtual resources. Tested with latest Chrome and Firefox on Ubuntu 20.04 and Windows 10 Pro - it's pretty usable, there is a small lag of course - something like a regular VNC connection but nothing severe.

Ok, we will try to record and compare the performance between 'traditional ' vnc and newly implemented novnc console.

@luhaijiao We've not heard from you since last few weeks, let us know if you've the issue and how can we produce it. Until then I've kept it outside of any milestone. Thanks.

Ping @luhaijiao any update? Is this still an issue we should be tracking for 4.15.1 or is it an environment issue?

Closing this as we've not heard any update, @luhaijiao kindly test against 4.15.1.0 and re-open if you've any advice for us to reproduce and help address this. Thanks.

> Anyone tested the novnc console of Windows Server VM ? just would like to isolate if it's a pure environment issue of our own.
@luhaijiao could you record the screenshots of cloudstack novnc console and cloudstack vnc console (novnc.console.default=false) of same vm ?

Sorry for confusion, guys.
First of all, all our testing is based on intranet environment, CPVM and users are in the same location.
The significant novnc console lag happens to Windows Server VMs, e.g. Windows Server 2012/2016, Windows 10 is not tested yet.
Same lag happens to Ubuntu Desktop too.
However, novnc console looks good with most Linux VMs.
The performance gap is like one VM with VMware tools installed vs one without VMware tools.

[GitHub] [cloudstack] rhtyd commented on issue #4660: Extremely laggy to access Windows guests via NoVNC console

@div8cn when you say cloudstack console, you mean the old/legacy console or the new novnc console. The CPVM essentially proxies the console between the hypervisor and browser, which may be cause of that latency. Is the user/browser away from the CPVM/infrastructure.

I compared cloudstack console, novnc and VNC view
There is no difference between VNC view and novnc
However, the delay of cloudstack console is very serious
It is shown in the following aspects
When moving the mouse, I feel that the mouse is very heavy and difficult to move

The test computer and cloudstack CPVM belong to the same layer-3 routing and different VLANs, Local to CPVM network delay < 5ms
I deployed a Ubuntu 20.04 guest OS
The test effect is also very bad
It's like VMware VM doesn't have a console experience with vmtools installed

@div8cn thanks, how far is the user/browser from the CPVM (for example is CPVM say is in London and user in Australia)? And, does it happen only for Windows, what about any Linux distro with a desktop say Ubuntu Desktop?

@div8cn sorry I didn't understand your statement, are you seeing laggy novnc console with Ubuntu 20.04 Desktop as well? And are you saying this is caused by VMs with openvmtools/vmware-tools installed?

Anyone tested the novnc console of Windows Server VM ? just would like to isolate if it's a pure environment issue of our own.
