RE: [Xen-devel] out-of-memory problem when restoring ballooneddomains
Please can you try this out with 2.0.5 -- there have been a bunch of fixes in these general areas, though I''m not sure it''ll be fixed for you.

RE: [Xen-devel] out-of-memory problem when restoring ballooneddomains
No, unfortunately that didn''t help. (I was already running
2.0-testing from this morning PST, so I guess I already had most
(all?) of the patches, but I guess it was worth a try...)
Perhaps it is not related to memory... When I try
to restore only t1 and t3, they also fail with ''Error: 1''
Perhaps it is because t1 and t3 both did run on CPU 0 while
t2 did run on CPU 1 (at least it says ''(cpu 0)'' in
{t1,t3}.saved.
It was only a guess that it was memory related. Could there
be some other explanation - CPU related?
Perhaps it is useful to see the trace from xend...
I started it with /usr/sbin/xend trace_start and
I cut out the relevant part (I think), where xend starts
to process the request to restore t3.saved. It
eventually ends up at _perform_err which logs the
error I mentioned earlier:
[2005-03-10 12:43:44 xend] ERROR (SrvBase:162) op=restore: 1
None
Thanks again for looking into this!
