Network issue - self-hosted engine on a single host
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?
Hi Jakov, The oVirt architecture basics: - The self-host engine is a VM running on a KVM host. To deploy a self-hosted engine, you must have a shared storage like a NFS share or iSCSI LUN. - Running the engine-setup command will deploy the stand-alone engine. The host running a stand-alone engine cannot act as a hypervisor at the same time. Acting as an Administration server and a Hypervisor at the same time is not allowed.
