Hi, I have observed strange ping timeouts/network issues when one of nodes is down, for example, for RAM upgrade. Powering up and connecting node back solves this. Each node have 2 networks (connected to different Ethernet interfaces), ovirtmgmt 192.168.0.xxx and DMZ 192.168.1.x. Additionally, time consuming operations like VM cloning causes increase of ping latency to ALL nodes from local workstations. VM cloning should load only 1 node but it should not affect the whole ovirt mgmt network on all nodes. How to fix this issue? Thanks in advance for any help. Andrei
