[Feedback Needed] oVirt metrics store
by Shirly Radco 23 May '19

23 May '19

Hi, In the latest oVirt 4.3.z and 4.2.z releases we have simplified the metrics store installation immensely and updated it to be based on OpenShift 3.11, with Elasticsearch and Kibana 5. The oVirt metrics store provides monitoring for the oVirt hosts and vms, for both metrics and logs with pre-built example dashboards and self service visualizations in Kibana. 5 steps for installing oVirt metrics store: 1. Update variables files 2. Run 1st ansible playbook -> creates the vms 3. Run 2nd ansible playbook -> deploys the metrics store on the created vms 4. Run 3rd ansible playbook -> configures the data collectors on the oVirt hosts and engine 4. Load example dashboards to Kibana In addition, we have replaced Fluentd with Rsyslog in 4.3.z hosts, for better performance. I invite you to try it out and give us feedback. - Installation guide - https://ovirt.org/documentation/metrics-install-guide/metrics_store_install… - User guide - https://ovirt.org/documentation/metrics-user-guide/metrics-user-guide.html - Short installation video <https://dms.licdn.com/playback/C5605AQHirxO3r-3OFw/14a815a1904945ac83774d7e…> Best regards, -- SHIRLY RADCO BI SENIOR SOFTWARE ENGINEER Red Hat Israel <https://www.redhat.com/> <https://red.ht/sig>

enabling vPMU for virtual machine
by Jarosław Prokopowski 23 May '19

23 May '19

Hi Guys, Is there a way to enable vPMU for VM in oVirt? I already enabled Nested Virtualization on hosts and installed vdsm-hook-nestedvt. In libvirt it is possible to set <cpu mode='host-passthrough'/> This blog post shows how to set it in libvirt xml vm config: https://stackoverflow.com/questions/46490857/how-to-enable-pmu-in-kvm-guest A clue from Red Hat: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/ht… Maybe something with cpuflags? https://mpolednik.github.io/2017/07/31/cpuflags-ovirt-hook-cpu-features/ Thanks Jarek

"Upgrade" from oVirt to RHV
by Vinícius Ferrão 23 May '19

23 May '19

Hello, I would like to know if there’s a supported path to move from oVirt to RHV. oVirt is running on version 4.3.0.4-1.el7. RHV would be version 4.3.3.7-0.1.el7. I was thinking in reinstalling a host with RHV 4.3 and adding it to the oVirt HE. Move all the VM’s to the RHV host and than do the same process. After it install a new RHVH-M to remove the oVirt Engine. Not sure if this would work or not. Thanks,

Unable to deploy Hyperconverged Engine Node - v4.3.3
by anonmix＠gmail.com 22 May '19

22 May '19

Hi everyone, I am trying a Gluster Hyperconvergence deployment where the Gluster part has been completed successfully. All hosts are Centos 7.6.1810 (fresh install) and two HP DL20 G9 (for VM's) and one HP 120 G7 (which hosts the Gluster arbiter volumes). Unfortunately I am unable to deploy the Engine, both CLI and GUI approaches fail with the error below. On first sight it looks similar to https://lists.ovirt.org/pipermail/users/2018-March/087802.html but I've configured a static IP (same subnet as the host), no DHCP. I also tried to force ipv4 with "/usr/sbin/ovirt-hosted-engine-setup --4" but the very same error was thrown in every case when trying to deploy the engine: [ ERROR ] fatal: [localhost]: FAILED! => {"ansible_facts": {"ovirt_hosts": [{"address": "sub.sub.domain.tld", "affinity_labels": [], "auto_numa_status": "unknown", "certificate": {"organization": "sub.domain.tld", "subject": "O=sub.domain.tld,CN=sub.sub.domain.tld"}, "cluster": {"href": "/ovirt-engine/api/clusters/f083f056-74fd-11e9-bba9-00163e522076", "id": "f083f056-74fd-11e9-bba9-00163e522076"}, "comment": "", "cpu": {"speed": 0.0, "topology": {}}, "device_passthrough": {"enabled": false}, "devices": [], "external_network_provider_configurations": [], "external_status": "ok", "hardware_information": {"supported_rng_sources": []}, "hooks": [], "href": "/ovirt-engine/api/hosts/dc4f5c15-4989-4454-ba46-3bd600796b69", "id": "dc4f5c15-4989-4454-ba46-3bd600796b69", "katello_errata": [], "kdump_status": "unknown", "ksm": {"enabled": false}, "max_scheduling_memory": 0, "memory": 0, "name": "sub.sub.domain.tld", "network_attachments": [], "nics": [], "numa_nodes": [], "numa_supported": fals e, "os": {"custom_kernel_cmdline": ""}, "permissions": [], "port": 54321, "power_management": {"automatic_pm_enabled": true, "enabled": false, "kdump_detection": true, "pm_proxies": []}, "protocol": "stomp", "se_linux": {}, "spm": {"priority": 5, "status": "none"}, "ssh": {"fingerprint": "SHA256:L8YyAMcxLFJEng+CoDympwkpMwoagcBafI4fpLP4Kk0", "port": 22}, "statistics": [], "status": "install_failed", "storage_connection_extensions": [], "summary": {"total": 0}, "tags": [], "transparent_huge_pages": {"enabled": false}, "type": "rhel", "unmanaged_networks": [], "update_available": false, "vgpu_placement": "consolidated"}]}, "attempts": 120, "changed": false} Unfortunately I don't really have an idea where to check for what considering the error message. The to be deployed engine VM gets listed as KVM VM, is accessible through the bridge and seems to be started up completely, I can even access the Engine web interface (engine01.sub.domain.tld/ovirt-engine). In /var/log/messages the following can be found ... "May 13 12:40:55 host ansible-async_wrapper.py: 15505 still running (86015) May 13 12:40:57 host python: ansible-ovirt_host_facts Invoked with all_content=False pattern=name=sub.sub.domain.tld fetch_nested=False nested_attributes=[] auth={'timeout': 0, 'url': 'https://engine01.sub.domain.tld/ovirt-engine/api', 'insecure': True, 'kerberos': False, 'compress': True, 'headers': None, 'token': '8s-vELzQqNTR6l7-KRuqnYLE3sVwVWU5NxiNWzc-s2CllaQG_5YZ32fCFkVsAgwEyLWjPIOxvyS-_4js-VYFFQ', 'ca_file': None}" ... and after 120 attempts Ansible stops and fails with a deployment error. When re-trying after removing the VM and ovirt-hosted-engine-cleanup the very same error is thrown.

ovirt 4.3.3.7 cannot create a gluster storage domain
by Strahil Nikolov 22 May '19

Hey guys, I have recently updated (yesterday) my platform to latest available (v4.3.3.7) and upgraded to gluster v6.1 .The setup is hyperconverged 3 node cluster with ovirt1/gluster1 & ovirt2/gluster2 as replica nodes (glusterX is for gluster communication) while ovirt3 is the arbiter. Today I have tried to add new domain storages but they fail with the following: 2019-05-16 10:15:21,296+0300 INFO (jsonrpc/2) [vdsm.api] FINISH createStorageDomain error=Command ['/usr/bin/dd', 'iflag=fullblock', u'of=/rhev/data-center/mnt/glusterSD/gluster1:_data__fast2/591d9b61-5c7d-4388-a6b7-ab03181dff8a/dom_md/xleases', 'oflag=direct,seek_bytes', 'seek=1048576', 'bs=256512', 'count=1', 'conv=notrunc,nocreat,fsync'] failed with rc=1 out='[suppressed]' err="/usr/bin/dd: error writing '/rhev/data-center/mnt/glusterSD/gluster1:_data__fast2/591d9b61-5c7d-4388-a6b7-ab03181dff8a/dom_md/xleases': Invalid argument\n1+0 records in\n0+0 records out\n0 bytes (0 B) copied, 0.0138582 s, 0.0 kB/s\n" from=::ffff:192.168.1.2,43864, flow_id=4a54578a, task_id=d2535d0f-c7f7-4f31-a10f-704923ce1790 (api:52) 2019-05-16 10:15:21,296+0300 ERROR (jsonrpc/2) [storage.TaskManager.Task] (Task='d2535d0f-c7f7-4f31-a10f-704923ce1790') Unexpected error (task:875) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 882, in _run return fn(*args, **kargs) File "<string>", line 2, in createStorageDomain File "/usr/lib/python2.7/site-packages/vdsm/common/api.py", line 50, in method ret = func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/storage/hsm.py", line 2614, in createStorageDomain storageType, domVersion, block_size, alignment) File "/usr/lib/python2.7/site-packages/vdsm/storage/nfsSD.py", line 106, in create block_size) File "/usr/lib/python2.7/site-packages/vdsm/storage/fileSD.py", line 466, in _prepareMetadata cls.format_external_leases(sdUUID, xleases_path) File "/usr/lib/python2.7/site-packages/vdsm/storage/sd.py", line 1255, in format_external_leases xlease.format_index(lockspace, backend) File "/usr/lib/python2.7/site-packages/vdsm/storage/xlease.py", line 681, in format_index index.dump(file) File "/usr/lib/python2.7/site-packages/vdsm/storage/xlease.py", line 843, in dump file.pwrite(INDEX_BASE, self._buf) File "/usr/lib/python2.7/site-packages/vdsm/storage/xlease.py", line 1076, in pwrite self._run(args, data=buf[:]) File "/usr/lib/python2.7/site-packages/vdsm/storage/xlease.py", line 1093, in _run raise cmdutils.Error(args, rc, "[suppressed]", err) Error: Command ['/usr/bin/dd', 'iflag=fullblock', u'of=/rhev/data-center/mnt/glusterSD/gluster1:_data__fast2/591d9b61-5c7d-4388-a6b7-ab03181dff8a/dom_md/xleases', 'oflag=direct,seek_bytes', 'seek=1048576', 'bs=256512', 'count=1', 'conv=notrunc,nocreat,fsync'] failed with rc=1 out='[suppressed]' err="/usr/bin/dd: error writing '/rhev/data-center/mnt/glusterSD/gluster1:_data__fast2/591d9b61-5c7d-4388-a6b7-ab03181dff8a/dom_md/xleases': Invalid argument\n1+0 records in\n0+0 records out\n0 bytes (0 B) copied, 0.0138582 s, 0.0 kB/s\n" 2019-05-16 10:15:21,296+0300 INFO (jsonrpc/2) [storage.TaskManager.Task] (Task='d2535d0f-c7f7-4f31-a10f-704923ce1790') aborting: Task is aborted: u'Command [\'/usr/bin/dd\', \'iflag=fullblock\', u\'of=/rhev/data-center/mnt/glusterSD/gluster1:_data__fast2/591d9b61-5c7d-4388-a6b7-ab03181dff8a/dom_md/xleases\', \'oflag=direct,seek_bytes\', \'seek=1048576\', \'bs=256512\', \'count=1\', \'conv=notrunc,nocreat,fsync\'] failed with rc=1 out=\'[suppressed]\' err="/usr/bin/dd: error writing \'/rhev/data-center/mnt/glusterSD/gluster1:_data__fast2/591d9b61-5c7d-4388-a6b7-ab03181dff8a/dom_md/xleases\': Invalid argument\\n1+0 records in\\n0+0 records out\\n0 bytes (0 B) copied, 0.0138582 s, 0.0 kB/s\\n"' -

I see that this was apparently a bug in previous version, but I'm currently using oVirt Node 4.3.3.1. This was working fine before updating from oVirt Node 4.2. This occurs when trying to change the CD on a running VM.

vGPU becomes very inefficient when I use it in ovirt instead of qemu-kvm
by weizhengya16＠gmail.com 22 May '19

22 May '19

We distribute vGpu in order to use it in virtual machines. I find the same type vGpu get differently performance in Ovirt and Qemu-kvm . when I distribute a vGPU to Ovirt virtual machine,it's performance becomes very strange.Some games can run efficiently and attach 200+ fps.However,in some other games,it's can't even attach 10 FPS. But in Qemu-kvm,the vGpu's performance always efficiently,can run these games all in 200+fps. I've been stuck with this for weeks and I have to make it always runs efficiently. Can someone help me?Thank you very very very much....
