Xen devel - Oct 2006 - Xen save/restore problem

Hi there,

I have noticed a problem when saving and restoring a domain. In my setup the
network backend of a domain (domain A) is another guest domain (domain B) and
not dom0. When I save and restore domain A, it fails to re-establish the
connection to the network backend on domain B. The error message I get is:

vif vif-0: 2 reading other end details from device/vif/0
xenbus: resume (talk_to_otherend) vif-0 failed: -2

This error does not appear when the backend is dom0. I have all the xen scripts
in /etc/xen in domain B. Not sure why I am getting this error. It would be
great if someone can give me leads to solve the problem.

thanks,
Sanjee

The tools save/restore code is simply not there for driver domains.
