Having newly compiled a Libvirt on a Windows Vista machine (many thanks to Matthias Bolte) I have attempted to connect to a remote Ubuntu machine using virsh.exe.  However, the connection fails as follows:

$ virsh -c qemu+tcp:///system

error: unable to connect to libvirtd at 'localhost': errno=10061

error: failed to connect to the hypervisor

1.  I have modified /etc/libvirt/libvirt.conf to set listen_tcp=1.

2.  I cannot find /etc/sysconfig/libvirtd so I am unable to set LIBVIRTD_ARGS="--listen".

As stated on a previous post, my background is Windows rather than Linux, so I am at a loss as to know where to look next.  I would very much appreciate some guidance.  Many thanks in anticipation...
