libvirt users - Feb 2012 - 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.
Libvirt URI is: qemu:///system

- The 'libvirtd' daemon has been started

111,in openAuth
   if ret is None:raise libvirtError('virConnectOpenAuth()

-- end --

Is virt-manager running on the kvm host or guest?

If its the guest you cant connect to local host.  The VM is not aware its a
VM so you have to connect to the KVM server using the remote connection
URI.  Like this ..

qemu+ssh://user at kvmhost.tld/

Id recommend looking up setting a normal user to manage KVM so you can use
SSH + auth key.
