Hosted Engine setup issues
by Jeremy Tourville 21 Aug '18

21 Aug '18

If I try to setup hosted engine with the option to use Ansible it eventually fails on me. See https://lists.ovirt.org/archives/list/users@ovirt.org/thread/LPK7OGFALSQFAN… However if I run hosted-engine --deploy --noansible the setup does complete. There is further trouble though, it seems the networks are not being configured properly. If I browse to Compute>Hosts>Hostname and click on the Setup Host Networks button I am presented with a new window that contains an unassigned logical network of "oivrtmgmt" On the left side pane there are two columns for Interfaces and Assigned Logical Networks. Both of those columns are completely empty. I think if I understand correctly the interfaces column should at least have some info in it. [cid:bb1f29b4-888c-410a-9b47-7589f866539a] So my best guess is that for some unknown reason (at least to me) the Engine doesn't '"know how to get setup properly" either with or without Ansible. That's about as well as I can describe it. I hope it makes sense.... Anyone have ideas on what is going wrong here? Thanksfor any troubleshooting advice you can provide!

IPTables firewall to firewalld
by p.staniforth＠leedsbeckett.ac.uk 21 Aug '18

Hello, I get the following messages. "Cluster Default uses IPTables firewall, which has been deprecated in 4.2 of the engine, and will no longer be supported starting with version 4.3. Make sure to switch to Firewalld before upgrading to 4.3." If the correct way to change to firewalld edit cluster, and run reinstall? Thanks, Paul S.

Failed to run check-update of host
by Jayme 20 Aug '18

20 Aug '18

I have a fairly recent three node HCI setup running 4.2.5. I've recently updated hosted engine to the latest version (including yum updates). When I check for host updates through the engine gui I get the following error for all three of my hosts: Failed to check for available updates on host XXXXX with message 'Failed to run check-update of host 'XXXXXX'.'. The engine.log shows not much more detail: 2018-08-20 14:26:28,396-03 ERROR [org.ovirt.engine.core.bll.host.HostUpgradeManager] (EE-ManagedThreadFactory-commandCoordinator-Thread-2) [4400c1d5-5412-4f1a-9c25-40fe0fb53295] Failed to run check-update of host 'XXXXX'. 2018-08-20 14:26:28,397-03 ERROR [org.ovirt.engine.core.bll.hostdeploy.HostUpdatesChecker] (EE-ManagedThreadFactory-commandCoordinator-Thread-2) [4400c1d5-5412-4f1a-9c25-40fe0fb53295] Failed to check if updates are available for host 'Orchard2' with error message 'Failed to run check-update of host 'XXXXX'.' 2018-08-20 14:26:28,411-03 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-commandCoordinator-Thread-2) [4400c1d5-5412-4f1a-9c25-40fe0fb53295] EVENT_ID: HOST_AVAILABLE_UPDATES_FAILED(839), Failed to check for available updates on host Orchard2 with message 'Failed to run check-update of host 'XXXXX'.'.

after upgrade from 4.2.3 to 4.2.5, problems with consoles + cockpit
by Jason Keltz 20 Aug '18

20 Aug '18

Hi.. After an upgrade from 4.2.3 to 4.2.5 last week, I notice that I have a console + cockpit problem. Immediately following the upgrade, everything seemed to be working fine. However, today, a couple of days after the upgrade, when I try to view any CentOS VM console, virt-viewer starts, and I see "Connected to graphic server", but there's no console output. This happens on all Linux VMs, though on my two windows VMs, the console still works. If I restart a Linux VM, I get the console back again, but what made me lose access to all the consoles? In addition, if I right click on one of my 4 hosts, and choose "Host Console", it connects to cockpit which reports: "No VM is running or defined on this host" even though there are plenty. I brought one host into maintenance mode, and rebooted it. I then started a few VMs there, and cockpit still doesn't show anything running. All of the hosts have all available ovirt updates, and are running the latest CentOS 7 kernel + O/S updates. Any ideas? There is no issue with firewall. Jason.

info about changing engine ip mode from dhcp to static
by Gianluca Cecchi 17 Aug '18

17 Aug '18

Hello, a colleague of mine installed oVirt engine 4.2.5 on a test CentOS 7.5 system and in its initial configuration he configured its ip via dhcp (using static ip assignment configured at dhcp server side). Now he would like to maintain the same ip/hostname for the engine but with a static configuration on the server. Any hint about how to achieve this? Thanks in advance, Gianluca

Network issues with oVirt 4.2 and cloud-init
