You have VMware Server intalled on Linux and you are not able to view console of the VM. You know that your VM is running as you can ping it, ssh it and you know that your resources are consumed. Sometimes, it could be that you can view the console with your account but when accessed remotely or via an application which uses VMware Server, you are not able to view the console.
This is typically a permission issue. Most likely, you would have installed VMware Server as root and the other application might be accessing with another account which doesnt have enough permissions to view the console.
Try doing a chmod -r 777 on all the virtual machine folders having this problem before launching it. You can give the appropriate permissions afterwards.
