Xen devel - Oct 2006 - Problem with xen save/restore

Hi there,

 

I have noticed a problem when saving and restoring a domain. I''m using
xen-unstable on i386. 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

Save/restore integration with Œdriver domains¹ simply does not exist. More
than anything this is a limitation of our save image format. It¹ll get
addressed as we design the new format, hopefully in time for 3.0.4.
