I had an issue with VNC keeps disconnecting and having the "Request failed" error thrown when trying to use VNC on a VM (system VM included). Sometime VNC works, sometime it doesn't.
I've read here https://www.mail-archive.com/users@cloudstack.apache.org/msg35058.html that issues with VNC might be because of CPVM and its host time aren't synced. I've set the host is configured with Asia/Kuala_Lumpur meanwhile CPVM is configured with UTC. My question is what's the best practice in setting up time zone for MS, KVM hosts etc? Do I leave everything to UTC? Is there any related links that I can refer to? Thank you.
