<div class="gmail_quote">2012/3/15 Jim Fehlig <<a href="mailto:jfehlig@suse.com">jfehlig@suse.com</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> While testing this patch, I noticed some strange problems wrt concurrent operations in the driver. E.g. if I start a migration and then query dominfo on the migrating domain, it kills the migration xen134: # virsh migrate --live sles11sp1-pv xen+ssh://xen142 error: internal error Failed to save domain '7' with libxenlight </blockquote><div>Strange. Found that doing whatever operation that needs to open a connect to the hypervisor (even "virsh version") will cause the same issue to live migration. While trying operation that calls do_open the connect, xc_shadow_control( in xc_domain_save) will fail. Non-live migration is OK. </div><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> Thanks! Jim </blockquote></div>
