Cannot connect to VM console

[kamanwu]

I have 2 machines. Both of installed version 8.2.2
Both hosts do NOT have any issue to open shell.

One machine 1, I created a VM (ubuntu 24.4 server). Use noVNC console to connect the VM, no issues as well.
One machine 2, I created a same VM (ubuntu 24.4 server). But noVNC cannot connect to the VM. If I use ssh to login, no issues as well.

When noVNC cannot connect to the VM, there is no errors show up. Just the screen freeze at the ubuntu server starting process. Any suggestion to debug this issue?

Thanks.

Upate:
If I reboot the VM on 2nd machine, I get the same results. So rebooting will not solve the issue, and it's NOT a random issue.
