The first thing to say is that this isn't a port of virt-manager. We
couldn't get that working on Windows because the Python stuff for
Win32 was too complicated. This is a port of virt-ctrl instead
(http://et.redhat.com/~rjones/virt-ctrl/) which is a far less powerful
virt-manager clone that I wrote in my spare time, just as an
experiment. (It's also a rather old version of virt-ctrl. I really
must update that package ...)
Anyway, you should be able to set up your Xen hosts so that TCP
(insecure) connections are possible. Assuming that libvirtd is
running, there should be a file /etc/libvirt/libvirtd.conf which you
can edit to enable TCP connections:
listen_tcp = 1
I believe you also need to edit /etc/sysconfig/libvirtd and uncomment:
and of course open firewall port 16509 if necessary.
Then you should be able to connect remotely using this URI:
TCP connections are totally insecure, so you should only do this on a
