Super Low VM disk IO via Shared Storage
by Vrgotic, Marko 24 Sep '19

24 Sep '19

Dear oVirt, I have executed some tests regarding IO disk speed on the VMs, running on shared storage and local storage in oVirt. Results of the tests on local storage domains: avlocal2: [root@mpollocalcheck22 ~]# dd if=/dev/zero of=/tmp/test2.img bs=512 count=100000 oflag=dsync 100000+0 records in 100000+0 records out 51200000 bytes (51 MB) copied, 45.9756 s, 1.1 MB/s avlocal3: [root@mpollocalcheck3 ~]# dd if=/dev/zero of=/tmp/test2.img bs=512 count=100000 oflag=dsync 100000+0 records in 100000+0 records out 51200000 bytes (51 MB) copied, 43.6179 s, 1.2 MB/s Results of the test on shared storage domain: avshared: [root@mpoludctest4udc-1 ~]# dd if=/dev/zero of=/tmp/test2.img bs=512 count=100000 oflag=dsync 100000+0 records in 100000+0 records out 51200000 bytes (51 MB) copied, 283.499 s, 181 kB/s Why is it so low? Is there anything I can do to tune, configure VDSM or other service to speed this up? Any advice is appreciated. Shared storage is based on Netapp with 20Gbps LACP path from Hypervisor to Netapp volume, and set to MTU 9000. Used protocol is NFS4.0. oVirt is 4.3.4.3 SHE.

Hello When running neofetch in spice/vnc console, terminal become unreadable, does it come from spice/vnc or graphic emulation or neofetch binary? Screenfetch alternative is ok. -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Internal Memory filter not satisfied question
by Vrgotic, Marko 24 Sep '19

24 Sep '19

Dear oVirt, I need help clarifying how internal memory filter is used, at which values it looks at. The log message below is clear, but I am failing to see from where are the memory values calculated, is it based on Guarenteed, Allocated or MaxAvailable memory a VM can get/have? Or something else. We have a shared cluster, with hosts having different memory amount: Tried to create 17VMs, and following errors were observed: 2019-09-20 11:46:10,496Z WARN [org.ovirt.engine.core.bll.RunVmCommand] (EE-ManagedThreadFactory-engine-Thread-967) [2d316914-84dc-4410-856f-f8576e411574] Validation of action 'RunVm' failed for user mvrgotic@ictv.com@ictv.com-authz.

Unexpected SSO error with first task
by Vrgotic, Marko 24 Sep '19

24 Sep '19

Dear oVirt, In our software tests, we deploy oVirt VMs using ansible and teardown also using ansible. We noticed that each time we run nightly tests, using Jenkins user in ovirt, in one of the Jobs, first task, creating VM, fails with following error, TASK [Login to oVirt] ********************************************************** An exception occurred during task execution. To see the full traceback, use -vvv. The error was: AuthError: Error during SSO authentication invalid_grant : The provided authorization grant for the username and password has expired. fatal: [PVyrZMy0-csm-2.avinity.tv<http://pvyrzmy0-csm-2.avinity.tv/> -> localhost]: FAILED! => {"changed": false, "msg": "Error during SSO authentication invalid_grant : The provided authorization grant for the username and password has expired."} Immediately after, Token seem to be renewed and all other VMs are created without issue. The play looks like following: --- # file: provision-ovirt.yml - name: Create VM in OVirt hosts: ovirt-vms gather_facts: false vars: - state: running pre_tasks: - name: Login to oVirt delegate_to: localhost ovirt_auth: url: "{{ ovirt_engine_url }}" username: "{{ ovirt_engine_user }}" password: "{{ ovirt_engine_password }}" ca_file: "{{ ovirt_engine_cafile | default(omit) }}" insecure: "{{ ovirt_engine_insecure | default(true) }}" run_once: true tasks: - name: "Get agent keys" delegate_to: localhost command: ssh-add -L register: ssh_agent_pubkeys run_once: true changed_when: False - name: Create new VMs from template delegate_to: localhost ovirt_vm: auth: "{{ ovirt_auth }}" name: "{{ inventory_hostname_short }}" nics: - name: nic1 profile_name: tenant1 interface: virtio cloud_init_nics: - nic_name: eth0 nic_boot_protocol: dhcp nic_on_boot: true cloud_init: host_name: "{{ inventory_hostname_short }}" authorized_ssh_keys: "{{ ssh_agent_pubkeys.stdout }}" state: "{{ state }}" cluster: "{{ovirt_cluster}}" template: "{{ images_to_template[os_image] }}" instance_type: "{{ os_flavor_to_ovirt_instance_type[os_flavor] }}" - name: "Wait until the ansible user can log into the host (cloud-init needs to have finished)" command: ssh -oPasswordAuthentication=no -oStrictHostKeyChecking=no {{ansible_user}}@{{inventory_hostname}} exit register: ssh_output delegate_to: localhost until: ssh_output.rc == 0 retries: 30 delay: 5 changed_when: False post_tasks: - name: Logout from oVirt delegate_to: localhost run_once: true ovirt_auth: state: absent ovirt_auth: "{{ ovirt_auth }}" tags: - always How does token relates to user session in oVirt? We would expect that once we logout, token should be expired and upon new login just get renewed/new token to proceed. Is it a bug? Is it in the play that we are doing something incorrectly? Kindly awaiting your eply. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic

Reboot a guest via ansible in oVirt
by Gianluca Cecchi 24 Sep '19

24 Sep '19

Hello, I see that there is this Ansible module for vSphere that contains also the state "restarted": https://docs.ansible.com/ansible/latest/modules/vmware_guest_powerstate_mod… For oVirt I see the ovirt_vm module where state can be one of: [ absent, next_run, present, registered, running, stopped, suspended, exported ] Can we think to add a restart / restarted one to it too? BTW: I see discrepancy between this page: https://www.ovirt.org/develop/release-management/features/infra/ansible_mod… where many module names and links to github source are plural (eg ovirt_disks) and actual ansible docs and github sources that are singular (eg. ovirt_disk) Thanks, Gianluca

ovirtmgmt STP disabled - any reason behind that
by Strahil Nikolov 23 Sep '19

23 Sep '19

Hi All, I recently got an issue and due to lack of debug time , I'm still not sure if it was a loop on the network.Can someone clarify why the ovirtmgmt bridge has STP disabled ? Any reason behind that ? Also, what is the proper way to enable STP on those bridges ? For now , I have set highest priority of the STP on my router and I don't expect the issue to reoccur (if it really was a loop), but I want to avoid future issues like that. Best Regards,Strahil Nikolov

Is there anyone who uses oVirt as a full VDI environment? I would have a bunch of questions...
