Hi guys Today I've found out that I need to update my nodes and reboot them. In order to prevent downtime in my production servers, I was live migrating VMs one by one to other nodes in my cluster. and migration problem occurred while migrating two of my VMs. They got rebooted and we experienced 2 minutes of downtime. I've just found this in error log as "migration problem" 2018-05-17 16:55:54 migration status: completed 2018-05-17 16:55:56 ERROR: tunnel replied 'ERR: resume failed - VM 130 not running' to command 'resume 130' 2018-05-17 16:56:24 ERROR: migration finished with problems (duration 00:02:42) TASK ERROR: migration problems Any Idea ?
