Hi,
Does the transport have any configuration file to throttle the
connections through ssh made from a client ?
The logs are huge even after compressing(5MB). Is there a site
where I can upload this to ?
Regards,
Navin

Hm those errors you pasted seem really strange. As it appears to work on
localhost, the problem will be probably in the transport itself.
As the log you posted contains only error messages it's hard to tell the reason
for this behavior.
One of the reasons might be that the machine name isn't resolving correctly.
Please try to fix your DNS or /etc/hosts file so that the resolution works.
Could you please post logs containing debug logs both from the client (refer to
http://libvirt.org/logging.html#log_library for steps to enable them) and also
from the server. Please attach them compressed as they tend to grow really
large after a short time.
Thanks
Peter
