[libvirt-users] virt-manager thru window's remote desktop

Hi, I am trying to operate the remote KVM host's virt-manager thru Terminal Server Client. This KVM hosts is CentOS6.0 and running KVM guest and xrdp is installed from "epel" repo. And I'm using fedora 14's Terminal Server Client. After I started Virtual Machine Manager and try to connect to the hypervisor, following error happened. Is there any way to resolve this error? I know that when I use VNC server , this error does not happened, but I want to use Terminal Server rather than VNC, because this doesn't need extra software for windows client PCs. -- Error snip -- Virtual Machine Manager Connection Failure Unable to open a connection to the libvirt management daemon.
