As far as I know several orgs are using AMD Ryzen CPUs with oVirt. Ryzen CPUs are quite nice from price/performance perspective.

Re: ovirt_disk and ubuntu issues
by Vrgotic, Marko 16 Jul '19

Dear oVIrt, Even though I would like to get some insight into what could be reason this is no working, I did find a workaround: Instead of trying to get Ubuntu disk specified with ovirt_disk size, I used qemu-img resize to increase the disk size before importing it to oVIrt. This works, but it still going to present the problem if User eventually wants to increase for example disk from 40GBto 80GB. Kindly awaiting your reply. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic Sr. System Engineer @ System Administration m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> From: "Vrgotic, Marko" <M.Vrgotic(a)activevideo.com> Date: Wednesday, 10 July 2019 at 16:19 To: "users(a)ovirt.org" <users(a)ovirt.org> Subject: ovirt_disk and ubuntu issues Dear oVirt, I am downloading the ubuntu cloud image 16.04 and or 18.04: - name: "Download base cloud image from server" get_url: url: "{{ image_url }}" checksum: "sha256:{{ image_checksum }}" validate_certs: yes dest: "/tmp/{{ inventory_hostname_short }}.qcow2" delegate_to: localhost creating a 40GB HDD and attaching image to it: - name: "Create oVirt disk with base image (with 40Gb allocated)" ovirt_disk: name: "{{ inventory_hostname_short }}" interface: virtio size: 40GiB format: cow upload_image_path: "/tmp/{{ inventory_hostname_short }}.qcow2" storage_domain: ovirt_production wait: true delegate_to: localhost creating VM afterwards: - name: "Create new Ubuntu VMs from cloud image" delegate_to: localhost ovirt_vm: auth: "{{ ovirt_auth }}" name: "{{ inventory_hostname_short }}" disks: - name: "{{ inventory_hostname_short }}" graphical_console: protocol: vnc serial_console: true usb_support: true soundcard_enabled: false operating_system: "{{ operating_system_type }}" type: server nics: - name: nic1 profile_name: tenant1 interface: virtio nic_on_boot: true cloud_init: host_name: "{{ inventory_hostname }}" user_name: ubuntu authorized_ssh_keys: "{{ ssh_agent_pubkeys.stdout }}" state: "running" cluster: "{{ ovirt_cluster }}" when: inventory_hostname in groups['ubuntu-baker'] When VM gets created, I can see in oVIrt VM details disk created is 40GB.

Moving Hosted Engine Storage
by Dan Poltawski 16 Jul '19

16 Jul '19

Hello, I've read various posts[1] on this list, but I must confess that I am still not entirely clear on the process for moving a hosted engine to a new storage domain (in my case I want to move from an existing NFS server to a new iSCSI target). Some of what i've read make me slightly concerned it's a risky operation and in my situation I am just prototyping and retaining the existing engine will be saving some time rather than mission critical. Is anyone able to outline the steps to me? thanks, Dan [1] https://lists.ovirt.org/pipermail/users/2017-June/082466.html ________________________________ The Networking People (TNP) Limited.

I'm addding gluster-users as I'm not sure if you can go gluster v3 -> v6 directly. Theoretically speaking , there should be no problem - but I don't know if you will observe any issues. @Gluster-users, Can someone share their thoughts about v3 to v6 migration ?

VM status codes
by Mitja Mihelič 15 Jul '19

15 Jul '19

Hi! We are graphing certain parameters we collect from the engine database. We use following query to get the count of running VMs: select count(*),cluster.name as cluster from vms, cluster where vms.cluster_id = cluster.cluster_id and vms.status = 1 group by cluster; It would help extremely if we knew what the numeric VM status codes mean. For example, I know that "status = 1" means the VM is running. The ones we can cause through the web interface are easy enough to figure out. But there are error states, that cannot be produced by standard use. For instance, when the event log says "VM foobar has been paused due to storage I/O problem." the following states get set in the DB (Query used: select * from vm_dynamic where vm_guid =(select vm_guid from vm_static where vm_name = 'foobar';): status | 4 exit_status | 0 pause_status | 2 guest_agent_status | 0 What do they mean? If you could point me to a table somewhere with the state descriptions it would be extremely helpful. Kind regards, Mitja Mihelič

SSH Authorized_keys
by Vrgotic, Marko 15 Jul '19

15 Jul '19

Dear oVIrt, Would it be possible to utilize SSH Pub key from User config [cid:image001.png@01D53B2B.0E387070] In such a way that it is offered or autoloaded into Cloud-init SSH Authorized keys field when exists? This would bring one less action required before VM can be created. Kindly awaiting your reply. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic

Re: ovirt-engine-appliance ova
by Strahil 15 Jul '19

15 Jul '19

Exactly. Ovirt (and RHV respectively) can be installed as: 1. VM in an oVirt Cluster 2. Separate machine(s) In point 2 , the Virt admin should take care about the high availability of the engine. So, you can install CentOS7 and then deploy the engine's software ontop of it. Extracting the OVA will not provide you with fully working engine, as the deployment scripts on the hosts will not inject the necessary data on remote system. (Only on local) Best Regards, Strahil NikolovOn Jul 15, 2019 04:08, Jingjie Jiang <jingjie.jiang(a)oracle.com> wrote: > > > On 7/13/2019 6:28 AM, Strahil Nikolov wrote: > > I still don't get why you need the OVA . > Are you trying to extract and put it into another virtualization.
