VNC in KVM
Can anyone tell me why I cannot VNC into a KVM guest? I can, of course, connect to the external VNC provided by the providers that I have used, but I am always rejected when trying to connect directly to the guest. This remains true when using any VNC server that attempts to share the existing display (the one I am viewing via the provided external VNC). I am using desktop distributions, currently Ubuntu.
My errors range from just unable to connect to rejected, etc. The clients aren't very specific, but I've used multiple clients on two different operating systems. It would seem as though I am completely missing something about how KVM virtualization effects what I'm trying to do. Providers used have been Hostigation, BuyVM, and SonicVPS. The external VNC messes with my keyboard input and some of my preferred VNC client features, so it is not an option to simply use it.
Hoping someone here can shed some light on it.
