Hello to all, I am trying to build a two-node ovirt cluster, using a VNXe 3150 iSCSI SAN. The two physical machines used for hypervisors are HP DL380p servers, with 128GB RAM and two E5-2630. On both servers I created a 100GB logical volume used for GlusterFS, to install on top of it both the hosted engine used and the ISO repository. Installation was fine, and under Virtualization Manager, the datacenter seems OK and both hypervisors seems to be registered properly. I have also added the two hosts to the VNXe, created some iSCSI LUNs to test the whole platform and created iSCSI bond interfaces to enabled multipathing. My problem is that live VM migration only works to one direction, lets say from server VH1 to VH2, and not backwards. If I try to bring the VM back to VH1, I get the following: ===== Migration failed due to Error: Fatal error during migration (VM: Test_Centos_7, Source: hosted_engine_2, Destination: hosted_engine_1). ===== I cant seem (and to be honest dont know exactly how) to identify something in the log files. I have verified though that both servers are identical, with the same services up, SELinux disabled, firewalls down and ntp enabled and reporting same time. Now, if I powerdown the VM from VH2 and start it up again, it starts OK on VH1. Also, if I try to migrate the Hosted Engine itself, I get: ===== Error while executing action: HostedEngine: Cannot migrate VM. There are no available HA hosts in the VM's Cluster. Cannot migrate VM. There is no host that satisfies current scheduling constraints. See below for details: The host hosted_engine_2 did not satisfy internal filter HA. ===== and I have already enabled HA Reservation on the Cluster properties. Thank you in advance, Nick Vidiadakis
