xen discuss - Nov 2009 - xen start error after upgrade to b125

Hi,

just upgraded a machine from snv_b98 to snv_b125. Unfortunately domUs do
not start anymore:

# virsh start win2008ss
error: Failed to start domain win2008ss
error: POST operation failed: xend_post: error from xen daemon:
(xend.err ''signed integer is greater than maximum'')

Problem solved by re-defining all domains, i.e.
virsh dumpxml $domain >/tmp/$domain
virsh undefine $domain
virsh define /tmp/$domain

Adding an appropriate note to the wiki (e.g.
http://hub.opensolaris.org/bin/view/Community+Group+xen/SolarisAsGuestHost )
might be a good idea ...

Regards,
jel.

Did you keep any of the original xend config files by any chance? We''d
need those to have a chance to triage this bug.

We''re not familiar with this failure mode.
