äé: live-migration restore failed error We are working on live-migration based on Xen-4.0.1(For history reason, and meantime we are upgrading our Xen to very latest version). Restore failed when live migrating ubuntu12.04 on xen-4.0.1. To be more specific, error occurred when populating memory. Error messages are as follow: [2014-09-12 22:40:40 7331 1189091648] DEBUG (XendCheckpoint:307) [xc_restore]: /usr/lib64/xen/bin/xc_restore 4 2763 3 4 1 1 1 0

As I am debugging this issue, I'm sending this email to ask for suggestions on this issue. |
