Yes, I have only the gold crown on the host where the hosted engine is running. On the second host, there is no crown; that field is empty. When I installed it, I deployed the hosted engine on the host where I have the gold crown. After this step, I created the cluster and added the second host. Do I need to perform any additional steps every time I add a new host to the cluster to be able to migrate the hosted engine VM?

The "crown" symbol is on the host where the engine-host vm is running.

Hosted engine deployment fails on Rocky Linux 9
by mpelicci＠cisco.com 18 Jul '24

18 Jul '24

Trying to do a fresh install of ovirt 4.5 on a Rocky Linux 9 host. While running the hosted-engine --deploy --4, I input all of the information. Why is it that the hosted engine is trying to reach out to the CentOS8 repos and is there a way for me to pause the deployment to modify the repo files on the vm? [ INFO ] TASK [ovirt.ovirt.engine_setup : Install oVirt Engine package] [ ERROR ] fatal: [localhost -> 192.168.1.103]: FAILED! => {"changed": false, "msg": "Failed to download metadata for repo 'centos-ceph-pacific': Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=storage-cep… [Could not resolve host: mirrorlist.centos.org]", "rc": 1, "results": []} [root@lab-node1]# cat /etc/rocky-release Rocky Linux release 9.4 (Blue Onyx)

oVirt 4.5.5 compatibility with CPU
by jakov.jelinic＠adriatic.hr 18 Jul '24

18 Jul '24

Hi, We plan to install ovirt node 4.5.5 (https://resources.ovirt.org/pub/ovirt-4.5/iso/ovirt-node-ng-installer/) on our 2 new servers, but looking at the documentation (https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engin…) it seems that oVirt is not compatible with our CPU Intel Xeon Silver 4410Y 12C 150 W 2 .0 GHz processor? Can you help us?

fence_rhevm with oVirt >4.5
by justindavis＠mail.utexas.edu 18 Jul '24

18 Jul '24

Hello Folks Is the "fence_rhevm" package compatible with oVirt >4.5? We're converting our legacy RHV cluster to a new install of oVirt latest with NFS backed storage. Everything has been working smoothly with the exception of the RHV-M fencing device on this newly provisioned oVirt 4.5.7 cluster with RHEL 9.4 hosts -- I haven't been able to get authentication working between the fencing device and the manager appliance. The same configuration is working on both the legacy RHV 4.4 cluster (RHV nodes) and a test oVirt 4.5.6 cluster (RHEL 8.9 hosts). The primary difference that comes to mind between my test and new cluster is that the newest one was installed with Keycloak SSO default configs while it was disabled on the older test environment. I suspect it has something to do with dropping basic auth? Assuming this is the case, can Keycloak be removed without having to rebuild the cluster? Are there any significant drawbacks to disabling it? I've found docs for converting from AAA to Keycloak, but not the reverse. I see on the mailing list that the `ovirt-aaa-jdbc-tool` is deprecated and that Keycloak is strongly recommended moving forward -- is it possible to integrate an internal Keycloak implementation with the existing "fence_rhevm" package? The errors I'm seeing are: 401 Unauthorized This server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required. I've tried every variation of the <domain> value suggested -- including "admin@internal", "admin@ovirt@internal", "@admin@ovirt@internal-authz" Thanks in advance, Justin

Network issue - self-hosted engine on a single host
by jakov.jelinic＠adriatic.hr 16 Jul '24

16 Jul '24

Hi, I'm confused about installing ovirt as a self-hosted engine on a single host with local storage. I have one server which I have connected to 2 switches (which are in "Cisco stack"). I have connected the server with 2 UTP cables in master switch and 2 UTP cables in slave. I have installed on server Rocky Linux 9.4. And now i have 4 network interfaces (4 ip addresses) which i can ping from my computer. After that I installed ovirt engine 4.5.6-1.el9 with the next commands: > dnf install centos-release-ovirt45 > dnf install ovirt-engine > engine-setup Next step, I want to add a new host through my engine (Compute -> Hosts -> New). I started installing a new host. I choose my hostname to be my one and only server. After installation, I can no longer connect to my server: https://vhost01.testing.local/ovirt-engine/ because the ip address behind the dns name can no longer be pinged. Out of my 4 IP addresses, I can now ping only one from my computer. And then, of course, I change the DNS record and set it to that one-onlyworking IP address. So I think after adding the host my network is messed up. It even makes sense to me since everything is done on one host, and it seems to me that if I had separated the engine, it would not have these problems. This was my network before adding new host: ens13f0np0: connected to ens13f0np0 "Broadcom and subsidiaries BCM57454 NetXtreme-E 10Gb/25Gb/40Gb/50Gb/100Gb" ethernet (bnxt_en), 14:23:F2:5A:B8:E4, hw, mtu 1500 ip4 default inet4 192.168.50.60/24 route4 192.168.50.0/24 metric 100 route4 default via 192.168.50.2 metric 100 inet6 fe80::1623:f2ff:fe5a:b8e4/64 route6 fe80::/64 metric 1024 ens13flnpl: connected to ens13flnpl "Broadcom and subsidiaries BCM57454 NetXtreme-E 10Gb/25Gb/40Gb/50Gb/100Gb" ethernet (bnxt_en), 14:23:F2:5A:B8:E5, hw, mtu 1500 inet4 192.168.50.54/24 route4 192.168.50.0/24 metric 101 route4 default via 192.168.50.2 metric 101 inet6 fe80::1623:f2ff:fe5a:b8e5/64 route6 fe80::/64 metric 1024 ens13f2np2: connected to ens13f2np2 "Broadcom and subsidiaries BCM57454 NetXtreme-E 10Gb/25Gb/40Gb/50Gb/100Gb" ethernet (bnxt_en), 14:23:F2:5A:B8:E6, hw, mtu 1500 inet4 192.168.50.78/24 route4 192.168.50.0/24 metric 102 route4 default via 192.168.50.2 metric 102 inet6 fe80::1623:f2ff:fe5a:b8e6/64 route6 fe80::/64 metric 1024 ens13f3np3: connected to ens13f3np3 "Broadcom and subsidiaries BCM57454 NetXtreme-E 10Gb/25Gb/40Gb/50Gb/100Gb" ethernet (bnxt_en), 14:23:F2:5A:B8: E7, hw, mtu 1500 inet4 192.168.50.109/24 route4 192.168.50.0/24 metric 103 route4 default via 192.168.50.2 metric 103 inet6 fe80::1623:f2ff:fe5a:b8e7/64 route6 fe80::/64 metric 1024 lo: connected (externally) to lo "10" loopback (unknown), 00:00:00:00:00:00, sw, mtu 65536 inet4 127.0.0.1/8 inet6 ::1/128 route6:1/128 metric 256 virbro: connected (externally) to virbro "virbro" bridge, 52:54:00:11:F7:8C, sw, mtu 1500 inet4 192.168.122.1/24 route4 192.168.122.0/24 metric 0 and this is after adding new host: ens13f1np1: connected to ens13f1np1 "Broadcom and subsidiaries BCM57454 NetXtreme-E 10Gb/25Gb/40Gb/50Gb/100Gb" ethernet (bnxt_en), 14:23:F2:5A:B8:E5, hw, mtu 1500 ip4 default inet4 192.168.50.54/24 route4 192.168.50.0/24 metric 100 route4 default via 192.168.50.2 metric 100 inet6 fe80::1623:f2ff:fe5a:b8e5/64 route6 fe80::/64 metric 1024 ovirtmgmt: connected to ovirtmgmt "ovirtmgmt" bridge, 14:23:F2:5A:B8:E4, sw, mtu 1500 inet4 192.168.50.60/24 route4 192.168.50.0/24 metric 425 inet6 fe80::1623:f2ff:fe5a:b8e4/64 route6 fe80::/64 metric 1024 ens13f2np2: connected to ens13f2np2 "Broadcom and subsidiaries BCM57454 NetXtreme-E 10Gb/25Gb/40Gb/50Gb/100Gb" ethernet (bnxt_en), 14:23:F2:5A:B8:E6, hw, mtu 1500 inet4 192.168.50.78/24 route4 192.168.50.0/24 metric 101 route4 default via 192.168.50.2 metric 101 inet6 fe80::1623:f2ff:fe5a:b8e6/64 route6 fe80::/64 metric 1024 ens13f3np3: connected to ens13f3np3 "Broadcom and subsidiaries BCM57454 NetXtreme-E 10Gb/25Gb/40Gb/50Gb/100Gb" ethernet (bnxt_en), 14:23:F2:5A:B8:E7, hw, mtu 1500 inet4 192.168.50.109/24 route4 192.168.50.0/24 metric 102 route4 default via 192.168.50.2 metric 102 inet6 fe80::1623:f2ff:fe5a:b8e7/64 route6 fe80::/64 metric 1024 ens13f0np0: connected to ens13f0np0 "Broadcom and subsidiaries BCM57454 NetXtreme-E 10Gb/25Gb/40Gb/50Gb/100Gb" ethernet (bnxt_en), 14:23:F2:5A:B8:E4, hw, mtu 1500 master ovirtmgmt lo: connected (externally) to lo "lo" loopback (unknown), 00:00:00:00:00:00, sw, mtu 65536 inet4 127.0.0.1/8 inet6 ::1/128 route6 ::1/128 metric 256 br-int: disconnected "br-int" ovs-interface (openvswitch), 12:47:1C:18:8F:E2, sw, mtu 1500 Can you plese help?

HostedEngine migration fail
by doboscsongor＠gmail.com 16 Jul '24

16 Jul '24

Hi, I have two hosts in one cluster, where the hosts are exactly the same physical servers. The migration of virtual machines works fine, but I can't migrate the hosted engine VM. When I try to migrate it to the second host/server, the "Destination host" field in the migration pop-up window shows "No available host to migrate VMs to." However, if I try to migrate any other running VMs, the field becomes active and I can choose the second host/server. Screenshot: https://i.postimg.cc/YCnddhs1/ovirt.jpg Server software information: - OS Version: RHEL - 9.1.2206.0 - 23.el9 - OS Description: oVirt Node 4.5.5 - Kernel Version: 5.14.0 - 388.el9.x86_64 - KVM Version: 8.1.0 - 4.el9 - LIBVIRT Version: libvirt-9.5.0-6.el9 - VDSM Version: vdsm-4.50.5.1-1.el9 Thanks in advance!
