             Summary: Jenkins snapshot creation failed
                 Key: OVIRT-609
                 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-609
             Project: oVirt - virtualization made easy
          Issue Type: Bug

            Assignee: infra


[~ngoldin at redhat.com] issued a live snapshot creation on the Jenkins VM to prepare it for cluster move. This failed and it's not really clear why. Relevant event logs below, suggesting that the hypervisor  started dumping VM memory to the snapshot which caused a storage slowdown.

2016-Jun-23, 18:06 Snapshot 'ngoldin_before_cluster_move' creation for VM 'jenkins-phx-ovirt-org' was initiated by admin.

2016-Jun-23, 18:09 Failed to create live snapshot 'ngoldin_before_cluster_move' for VM 'jenkins-phx-ovirt-org'. VM restart is recommended. Note that using the created snapshot might cause data inconsistency.

2016-Jun-23, 18:13 Host ovirt-srv02 has network interface which exceeded the defined threshold [95%] (em1: transmit rate[100%], receive rate [0%])

2016-Jun-23, 18:13 Storage domain Production experienced a high latency of 18.7802 seconds from host ovirt-srv11. This may cause performance and functional issues. Please consult your Storage Administrator.
