on the client side:
virt-manager-0.5.3-8.el5
on the server side:
nc-1.84-10.fc6
libvirt-0.3.3-7.el5
xen-3.0.3-64.el5
both machines run with RHEL5.2. On the server I can loging without a password
(my pub key is in /root/.ssh/authorized_keys)
Attached is the relevant part of virt-manager.log
Any more info I can provide?
Thanks,
Alexander.
