Hi, thanks for your swift response. Unfortunately, it's not that kind of problem. The network isn't slow, since I'm using ONE for my diploma thesis I am writing at the university, so the connection is quite good. Also, the VMs aren't utilized at all, although yesterday it worked even under full utilization. The migration needed some time, but still it finished successfully. The problem I'm now having appears unfortunately even with the example-ttylinux-VM, so it has to be something else! :-/

Nothing else happens. For live-migration: Is the VM quite busy ? During live-migrate the RAM is synch'ed over to the new node, until nothing changes anymore. So if 1) your network is slow-ish (say, 100Mbit) and/or 2) you have one or many processes running within the VM which alter RAM, then the sync'ing can't keep up with the changes, hence the migration never finished. => ssh into the VM, "kill -STOP pids" the most active processes. You might observe that your cursor freezes for a second, then that was the migration (optionally: verify RUNNING), and "kill -CONT pids". Of course, it could also be something else Yours, Steffen -- IPB Halle AG Massenspektrometrie & Bioinformatik Dr. Steffen Neumann http://www.IPB-Halle.DE Weinberg 3 http://msbi.bic-gh.de 06120 Halle Tel. +49 (0) 345 5582 - 1470 +49 (0) 345 5582 - 0 sneumann(at)IPB-Halle.DE Fax. +49 (0) 345 5582 - 1409 _______________________________________________ Users mailing list [email protected] http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
