So, I'm attempting to understand something fully. My setup might not be ideal, so please provide me whatever education I may need. RE: https://access.redhat.com/solutions/202823 Quick background: I have (3) RHEV-H (ovirt node) Hypervisors with a hosted-engine. VM Migrations currently are not working and I have the following errors in the vdsm.log: --- "[RHEV]Failed to migrate VM between hypervisor with error "gaierror: [Errno -2] Name or service not known" in vdsm.log" --- Reading the RedHat article leads me to believe that this is a name resolution issue (for the FQDNs), but that leads to another question which I'll get to. First, a little more about the setup: I have separate IP networks for Management (ovirtmgmt), Storage, and VM Migration. These are all on unique IP ranges. I'll make up some for my purposes here: MGMT_VLAN: 10.25.250.x/24 STORAGE_VLAN: 10.26.3.x/24 MIGRATE_VLAN: 10.26.5.x/24 In anticipation for setting all of this up, I assigned hostnames/IPs for each role on each node/hypervisor, like so: vnode01 vnode01-sto (storage) vnode01-vmm vnode02 vnode02-sto vnode02-vmm etc., etc. So, I'm trying to understand what my best procedure for setting up a separate migration network and what IP/hostname settings are necessary to ensure that this works properly and wouldn't affect other things. I'm going to do some more reading right now, but at least I feel like I'm on the right path to getting migrations working. Please help lol Thanks as always, -- Chris
