A remote proxy provides remote control to a virtualization system. The virtualization system includes a computer having virtualization software executing on the computer, and one or more virtual machines executing on the computer by way of the virtualization software, each of the virtual machines having a guest operating system. The remote proxy receives over a network connection a plurality of logical channels of a multi-channel remote control protocol at a first domain of a plurality of domains of the virtualization system. Each of the logical channels convey information corresponding to one of the domains. For each logical channel, the remote proxy identifies the corresponding domain. Further, for each of the logical channels corresponding to a domain other than the first domain, the remote proxy forwards the logical channel to the corresponding domain.
