Looks like VDSM was slow to respond (probably due to storage slowness) while the snapshot
is likely to have completed fine. I'll review host logs and share my findings.
Jenkins snapshot creation failed

Key: OVIRT-609
URL: https://ovirt-jira.atlassian.net/browse/OVIRT-609
Project: oVirt - virtualization made easy
Issue Type: Bug
Reporter: Evgheni Dereveanchin
Assignee: infra
[~ngoldin(a)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, 18:09 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.{quote}
