Extremely laggy to access Windows guests via NoVNC console #4660
Description
Activity
@davidjumani @weizhouapache is this a known issue?
Haven't faced it, @vladimirpetrov have you encountered this ?
I haven't noticed such problem but will test and report back.
@luhaijiao what browser version are you using? Have you tried with different browsers and OS-es?
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.
Test environment
Windows 10
Google Chrome: 88.0.4324.190

guest-agentI compared cloudstack console, novnc and VNC view
There is no difference between VNC view and novnc
However, the delay of cloudstack console is very seriousIt is shown in the following aspects
When moving the mouse, I feel that the mouse is very heavy and difficult to move@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.
- Console refers to cloudstack new console (novnc)
- The test computer and cloudstack SSVM belong to the same layer-3 routing and different VLANs
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 installed4 remaining items
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 ?
Ping @luhaijiao any update? Is this still an issue we should be tracking for 4.15.1 or is it an environment issue?
Ok, we will try to record and compare the performance between 'traditional ' vnc and newly implemented novnc console.
Thanks @luhaijiao pl keep us updated.
@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.
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.
Windows 10 is laggy with Cloudstack 4.18.2.1(linux pretty smooth), Am I missing something. Is anyone else have the same issue

Windows requires more cpu and memory than linux.
also some drivers are missing in Windows, for example virtio.
try- install windows-virtio drivers (for disk and network, etc)
- stop the vm, change OS type of vm to 'Windows PV', then start it.
Hi @weizhouapache , Thanks for the suggestion, I have already installed windows-virtio driver, still mouse laggs ,
-----My Observation-----
The video driver model cirrus & virtio makes the windows mouse laggy, if I change the agent.properties file settings variable vm.video.hardware to "qxl" windows works fine and that makes linux mouse laggy(KVM hypervisor).
