When i am going to the System state -> Graphical Console for windows VPS and i it shows me the following error:

VNC has been configured on this system by Cloudmin, but the VNC server on port 5903 on host system cloudmin.postcy.com is not accessible. If it was just enabled, the system will need to be rebooted before VNC is available.



Are you using Xen or KVM virtualization there?

Also, are ports 5900 - 5910 open on the host system's firewall?

I using XEN. port is open also I disable the iptables but still the same..

So this could be a VNC issue, or a Windows VM issue ..

If you edit the VM's Xen .cfg file on the host system (usually under the /xen directory), does it contain a line like :

vfb = "type=vnc,vncunused=1,vncpasswd=yourpassword,vnclisten="

can i send you details on private email?

Did you ever get this resolved?

I have the exact same issue trying to connect to a XEN domU.

Here's what's in the config file:
