Add External Provider - OpenStack Glance - Test Failed - "Failed to communicate with the External Provider"
by Pravin Mohandass 25 Sep '19

25 Sep '19

We have installed Ovirt Manager 4.3 with couple of KVM compute host added into cluster. When we add OpenStack Glance as an External Provider, failing with following error message - "Failed to communicate with the External Provider" We are able to add the external provider for Openstack Neutron and Openstack Cinder and import the storage and network in to ovirt manager and use it for vm. We are getting following error message on engine.log file "Failed with error PROVIDER_FAILURE and code 5050". But we are able to fetch the images using postman tool. Requesting you to provide some insights on adding the Glance provider.

Messed up 4.2.3.1 installation - SSL handshake ERROR
by souvaliotimaria＠mail.com 25 Sep '19

25 Sep '19

Hello, everyone! So, I have an experimental installation of ovirt 4.2.3.1 with 3 nodes and glustered. Recently I deployed a new installation with ovirt 4.3.5.2, 3nodes and glustered storage here as well. The thing is, in my enthousiasm I thought "hey! what if I can import the experimental nodes as hosts in the new installation in a new cluster and see what happens? Will the 4.3.5.2 engine see them? Probably yeah. But will it see the VMs I have there?" And so I imported the experimental nodes. Without detaching them from their hosted engine. I could see the only VM that was active at the moment and not one of the suspended ones and of course I could not see the 4.2.3.1 HE VM. I have removed the hosts from the new installation and I have tried reconnecting the old engine and its nodes. Passwordless ssh works just fine, but the problem persists. hosted-engine --vm-status reports stale-data on node 2 and node 3 The thing is I know I messed the experimental installation (and I blame only my curiosity), SSL handshake is no longer feasable and I can't remove the hosts from the initial Cluster to Import them again. Basically everything is either in the process of activating without ever being able to do so or down or Non responsive. I would like to find a way around this, as I have seen in other posts in the ovirt forum that the SSL handshake error appears in some other cases and I would like to have a know-how if an occasion like this occurs in the future in production. Is it possible to re-deploy the engine on the nodes and not lose the glustered space or the existing VMs? Can the HE be destroyed and then deployed from scratch? What about the glustered space and the VMs' space? Will the VMs just take up space without being able to neither bring them up nor destroy them? I know I'm asking a lot and it was my fault to begin with but I am really curious if we can see this through. Thanks in advance

oVirt node - post-upgrade tasks
by dan.munteanu＠mdc-berlin.de 25 Sep '19

25 Sep '19

Dear oVirt community, recently I've started to use oVirt as a replacement for KVM + VirtManager and I've decided to use the oVirt Node installed on Dell EMC servers with self-hosted engine. So far, everything works fine, except that, each time I'm updating the nodes, I must reinstall Dell OMSA needed by the monitoring system (via SNMP). Is there any way to automatize the OMSA installation as a post-upgrade task/hook? Thank you Dan

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.

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
