Hi,
I can't seem to get libvirtd to accept remote connections. Both systems are
built using genunix's b130.
It seems that connections originating from the xvm0 server itself are fine but
as soon as I go on to the other box and run the same python script (or simply
virsh) the connection gets dropped immediately. Telnetting to port 16509
confirms that it drops the connection when it originates from outside of the
box, but telnetting from xvm0 it does work, connection doesn't get dropped.
Both systems are on the same subnet.
Looks like it's got something to do with credentials but I've not been able to
figure out what, or maybe I'm just doing something wrong.
