[OLVM] Host non responsive after installation
by alan＠softdrive.co 12 May '21

12 May '21

I am using Oracle Linux Virtualization Manager, following this guide: https://docs.oracle.com/en/virtualization/oracle-linux-virtualization-manag… After adding a host to the engine, the host becomes non responsive due to network errors: engine.log 2021-04-27 14:53:02,255Z ERROR [org.ovirt.engine.core.bll.hostdeploy.InstallVdsInternalCommand] (EE-ManagedThreadFactory-engine-Thread-32356) [38586e0e] Host installation failed for host 'c97604b3-5774-4260-92fd-633257aa7498', 'GPU2-2': Network error during communication with the host Help resolving this would be much appreciated!

Moving interfaces for switch maintenance
by David White 12 May '21

12 May '21

So I have two switches. All 3 of my HCI oVirt servers are connected to both switches. 1 switch serves the ovirtmgmt network (internal, gluster communication and everything else on that subnet) The other switch serves the "main" front-end network (Private). It turns out that my datacenter plugged the switches into the wrong power supplies, and now needs to move them. My switches have single PSUs, so when we move them, the network will go down. Obviously, I'm just going to move 1 switch at a time. What I'm wondering, though, is there's an "easy" way to force all the traffic for both networks out one of the single interfaces, so that I don't experience any more downtime during this switch maintenance. Should I assign another temporary IP address on each of the interfaces for each server that is in the same subnet as the switch we're going to take down? Sent with ProtonMail Secure Email.

Issue upgrading from 4.3 (Centos 7) to 4.4 (Centos 8)
by ling＠aliko.com 12 May '21

12 May '21

Hello, I have been trying to upgrade my self-hosted engine from 4.3 to 4.4 but running into issue while performing hosted-engine deploy. Old hypervisor hosts are all running Centos 8 and old ovirt-engine is also running Centos 7. I created a brand new baremental node running Centos 8, Kernel 4.18.0-240.15.1.el8_3.x86_64 and the following engine versions: ovirt-hosted-engine-setup-2.4.9-1.el8.noarch ovirt-hosted-engine-ha-2.4.6-1.el8.noarch ovirt-engine-appliance-4.4-20210323171213.1.el8.x86_64 python3-ovirt-engine-sdk4-4.4.10-1.el8.x86_64 I have many VLANs in my environment. But on this host, I only have these network devices set up (eth0 is the main network, eth1 for storage): # nmcli con NAME UUID TYPE DEVICE ovirtmgmt 02f64861-d992-4e56-8cec-da1906bac09f bridge ovirtmgmt System eth1 bd9e565f-bdc3-4e43-bbd3-5875b9d7fed7 ethernet eth1 virbr0 78e6875d-70f6-4c89-89dd-180dbb9250b1 bridge virbr0 eth0 743b0e26-aae7-44b8-9215-3754a537e90b ethernet eth0 vnet0 bcfead6d-c5b6-4428-9f89-41589735be02 tun vnet0 When I run hosted-engine --deploy --restore-from-file=backup_050321.bck, it hangs after showing: [ INFO ] TASK [ovirt.ovirt.engine_setup : Copy yum configuration file] [ INFO ] changed: [localhost -> ovirt.safari.apple.com] [ INFO ] TASK [ovirt.ovirt.engine_setup : Set 'best' to false] [ INFO ] changed: [localhost -> ovirt.safari.apple.com] [ INFO ] TASK [ovirt.ovirt.engine_setup : Update all packages] virsh shows the VM is in paused state: # virsh list Id Name State ---------------------------------- 1 HostedEngineLocal paused I was able to ssh onto the VM until that point. Do I need to set up all the network connection for all the VLANs before running the deploy script? And how about engine storage domain? I have a new NFS mount ready but it did not ask me about which storage domain to use. Will it ask in later stage? Thanks.

Something broke & took down multiple VMs for ~20 minutes
by David White 12 May '21

12 May '21

As the subject suggestions, something in oVirt HCI broke. I have no idea what, and it recovered on its own after about 20 minutes or so. I believe that the issue was limited to a single host (although I don't know that for sure), as we had two VMs go completely unresponsive, but a 3rd VM remained operational. For a while during the outage, I was able to log into the oVirt admin web portal, and I noticed at least 1-2 of my hosts (I have 3 hosts) showed the problematic VMs as being problematic inside of oVirt. Reviewing the oVirt Events, I see that this basically started right when the ETL Service Started. There were no events before that point since yesterday, but right when the ETL Service started, it seems like all hell broke loose. oVirt detected "No faulty multipaths" on any of the hosts, but then very quickly started indicating that hosts, vms, and storage targets were unavailable. See my screenshot below. Around 30 - 35 minutes later, it appears that the Hosted Engine terminated due to a storage issue, and auto recovered on a different host. There's a 2nd screenshot beneath the first. Everything came back up shortly before 9am, and has been stable since. In fact, the Volume replication issues that I saw in my environment after I performed maintenance on 1 of my hosts on Friday are no longer present. It appears that the Hosted Engine sees the storage as being perfectly healthy. How do I even begin to figure out what happened, and try to prevent it from happening again?

pool list vm assign user
by Dominique D 11 May '21

11 May '21

Is there a way to know how to see who the vm of a pool assigned to? I am able on the portal to see those who are "logged-in user" but the others VM I don't know to whom they are assigned.

Re: Changing the ovirtmgmt IP address

Found the answer: Update /var/lib/vdsm/persistence/netconf/nets/ovritmgmt and reboot. From: Matthew.Stier(a)fujitsu.com <Matthew.Stier(a)fujitsu.com> Sent: Monday, May 10, 2021 3:18 PM To: users(a)ovirt.org Subject: [ovirt-users] Changing the ovirtmgmt IP address Version: 4.3.10 I'm attempting to change the IP address, netmask and gateway of the ovirtmgmt NIC of a host, but everytime I reboot the host, the old address/netmask/gateway re-assert themselves. Where do I need to make the changes, so they will be permanent? I've modified /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt and route-ovirtmgmt, but they don't stick through a reboot.
