Re: Should I migrate existing oVirt Engine, or deploy new?

Hi Paul, Thanks for the response. I think you're suggesting that I take a hybrid approach, and do a restore of the current Engine onto the new VM. I hadn't thought about this option. Essentially what I was considering was either: - Export to OVA or something OR - Build a completely new oVirt engine with a completely new domain, etc... and try to live migrate the VMs from the old engine to the new engine. Do I understand you correctly that you're suggesting I install the OS onto a new VM, and try to do a restore of the oVirt settings onto the new VM (after I put the cluster into Global maintenance mode and shutdown the old oVirt)?

Migrating VM from old ovirt to a new one
by Facundo Badaracco 18 Sep '22

18 Sep '22

Hi everyone I would like to ask you a question I have an ovirt 4.4 which got corrupted certs and I can't access the gui. It gives me error 500 internal when I want to access. I have a new ovirt 4.5 on glusterfs which I would like to migrate all my vm's to. Is this possible? Can it be done by cli? It would save me from having to reinstall all the vm's.

Gluster setup for oVirt
by Jonas 18 Sep '22

18 Sep '22

Hello all I tried to setup Gluster volumes in cockpit using the wizard. Based on Red Hat's recommendations I wanted to put the Volume for the oVirt Engine on a thick provisioned logical volume [1] and therefore removed the line thinpoolname and corresponding configuration from the yml file (see below). Unfortunately, this approach was not successful. My solution is now to only create a data volume and manually create a thick provisioned gluster volume manually. What would you recommend doing? Thanks your any input :) Regards, Jonas [1]: https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infras… hc_nodes: hosts: server-005.storage.int.rabe.ch: gluster_infra_volume_groups: - vgname: vg_tier1_01 pvname: /dev/md/raid_tier1_gluster gluster_infra_mount_devices: - path: /gluster_bricks/tier1-ovirt-engine-01/gb-01 lvname: lv_tier1_ovirt_engine_01 vgname: vg_tier1_01 - path: /gluster_bricks/tier1-ovirt-data-01/gb-01 lvname: lv_tier1_ovirt_data_01 vgname: vg_tier1_01 blacklist_mpath_devices: - raid_tier1_gluster gluster_infra_thinpools: - vgname: vg_tier1_01 thinpoolname: lv_tier1_ovirt_data_01_tp poolmetadatasize: 16G gluster_infra_lv_logicalvols: - vgname: vg_tier1_01 lvname: lv_tier1_ovirt_engine_01 lvsize: 100G - vgname: vg_tier1_01 thinpool: lv_tier1_ovirt_data_01_tp lvname: lv_tier1_ovirt_data_01 lvsize: 16000G server-006.storage.int.rabe.ch: gluster_infra_volume_groups: - vgname: vg_tier1_01 pvname: /dev/md/raid_tier1_gluster gluster_infra_mount_devices: - path: /gluster_bricks/tier1-ovirt-engine-01/gb-01 lvname: lv_tier1_ovirt_engine_01 vgname: vg_tier1_01 - path: /gluster_bricks/tier1-ovirt-data-01/gb-01 lvname: lv_tier1_ovirt_data_01 vgname: vg_tier1_01 blacklist_mpath_devices: - raid_tier1_gluster gluster_infra_thinpools: - vgname: vg_tier1_01 thinpoolname: lv_tier1_ovirt_data_01_tp poolmetadatasize: 16G gluster_infra_lv_logicalvols: - vgname: vg_tier1_01 lvname: lv_tier1_ovirt_engine_01 lvsize: 100G - vgname: vg_tier1_01 thinpool: lv_tier1_ovirt_data_01_tp lvname: lv_tier1_ovirt_data_01 lvsize: 16000G server-007.storage.int.rabe.ch: gluster_infra_volume_groups: - vgname: vg_tier0_01 pvname: /dev/md/raid_tier0_gluster gluster_infra_mount_devices: - path: /gluster_bricks/tier1-ovirt-engine-01/gb-01 lvname: lv_tier1_ovirt_engine_01 vgname: vg_tier0_01 - path: /gluster_bricks/tier1-ovirt-data-01/gb-01 lvname: lv_tier1_ovirt_data_01 vgname: vg_tier0_01 blacklist_mpath_devices: - raid_tier0_gluster gluster_infra_thinpools: - vgname: vg_tier0_01 thinpoolname: lv_tier1_ovirt_data_01_tp poolmetadatasize: 1G gluster_infra_lv_logicalvols: - vgname: vg_tier0_01 lvname: lv_tier1_ovirt_engine_01 lvsize: 20G - vgname: vg_tier0_01 thinpool: lv_tier1_ovirt_data_01_tp lvname: lv_tier1_ovirt_data_01 lvsize: 32G vars: gluster_infra_disktype: JBOD gluster_infra_daling: 1024K gluster_set_selinux_labels: true gluster_infra_fw_ports: - 2049/tcp - 54321/tcp - 5900/tcp - 5900-6923/tcp - 5666/tcp - 16514/tcp gluster_infra_fw_permanent: true gluster_infra_fw_state: enabled gluster_infra_fw_zone: public gluster_infra_fw_services: - glusterfs gluster_features_force_varlogsizecheck: false cluster_nodes: - server-005.storage.int.rabe.ch - server-006.storage.int.rabe.ch - server-007.storage.int.rabe.ch gluster_features_hci_cluster: '{{ cluster_nodes }}' gluster_features_hci_volumes: - volname: tier1-ovirt-engine-01 brick: /gluster_bricks/tier1-ovirt-engine-01/gb-01 arbiter: 1 - volname: tier1-ovirt-data-01 brick: /gluster_bricks/tier1-ovirt-data-01/gb-01 arbiter: 1

static IP with OVN subnet
by ravi k 16 Sep '22

16 Sep '22

Hello, Hope you are all doing well. We have an interesting thing going on and so wanted to share with you all for some ideas and feedback. We configured a cluster with OVS switch and added an external network with subnet. So OVN started managing the subnet using DHCP. But here's the problem. When we add a nic with this network, an ip is assigned by DHCP. But we want an IP of our choice to be assigned. Here's what we tried. 1. We tried using the ovn-nbctl lsp-set-address like ovn-nbctl lsp-set-addresses 7840c97b-73c2-4246-a2a8-0e9e5b7f420a "56:6f:6b:54:00:ec 10.19.3.8" to update the static IP. But this does not persist a NIC unplug or a VM reboot. So you might ask why not just try assigning a static IP and not add the external subnet. We want to use security groups. For security groups to work, the ip assigned to the NIC and the IP in the value for fixed_ips in `openstack port show` should be the same. So the same thing repeats here as well. If we use the `openstack port set` to update the fixed_ips, a NIC unplug or a VM reboot will remove the IP. We have an internal IPAM that provides us IPs during our automated provisioning. Did anyone try this or have any ideas how to work around this? The only option seems to be just use DHCP and then update that IP in our internal IPAM tool. Please let me know if I'm unclear and any more info is required. Regards, rav

How does ovirt use cloudbase-init to initialize the Windows image

How does ovirt use cloudbase-init to initialize the Windows image? Sorry, I'm a beginner. I don't know if I use cloudbase-init, I install this program in the virtual machine image, but I don't know how to operate it in the ovirt console.
