[one-users] VM status is runn but it doesn't make contact

[Carlos Martín Sánchez]

Hi,

You don't need to start the VNC server inside the guest OS, OpenNebula can
create a VNC connection directly to the hypervisor. To do that, use the
GRAPHICS attribute [1]. You can then connect to the Host's IP, or just
click the VNC icon in Sunstone.

Regards
