[ovirt-users] migration infinite loop

Hi, I switch an host in "PreparingForMaintenance" state to prepare an upgrade. In this stage the host migrating all VM but failed on one due to a network's congestion. Because the host try to migrate this VM and the constant failure of the migration, we enter in an infinite loop. How can I stop this loop ? I’m not able to cancel the mainteance mode with the WebUI. Any idea ? Thanks -- Renaud
