ovirt_vm ansible module -- how to wait for ova export to finish
by Jayme 27 Jan '20

27 Jan '20

I wrote a simple task that is using the ovirt_vm module https://docs.ansible.com/ansible/latest/modules/ovirt_vm_module.html -- it essentially loops over a list of vms and exports them to OVA. The problem I have is the task is deemed changed once it successfully submits the export task to oVirt. This means that if I gave it a list of 100 Vms I believe it would start an export task on all of them. I want to prevent this and have it only export one VM at a time. In order to do this I believe I will need to find a way for the task to wait and somehow verify that the export was completed before submitting a task for the next VM export. Any ideas? - name: Export the VM ovirt_vm: auth: "{{ ovirt_auth }}" name: "{{ item }}" state: exported cluster: default export_ova: host: Host0 filename: "{{ item }}" directory: /backup/ with_items: "{{ vms }}"

Hi Team, I need a quick help from you. I need to upgrade ovirt host server from 4.1 to 4.2 version but i am getting below errors :- --> Finished Dependency Resolution Error: Package: nfs-ganesha-nullfs-2.3.3-1.el7.x86_64 (@ovirt-4.1-centos-gluster38) Requires: nfs-ganesha = 2.3.3-1.el7 Removing: nfs-ganesha-2.3.3-1.el7.x86_64 (@ovirt-4.1-centos-gluster38) nfs-ganesha = 2.3.3-1.el7 Updated By: nfs-ganesha-2.5.5-1.el7.x86_64 (ovirt-4.2-centos-gluster312) nfs-ganesha = 2.5.5-1.el7 Available: nfs-ganesha-2.5.2-1.el7.x86_64 (ovirt-4.2-centos-gluster312) nfs-ganesha = 2.5.2-1.el7 Available: nfs-ganesha-2.5.3-1.el6.x86_64 (ovirt-4.2-centos-gluster312) nfs-ganesha = 2.5.3-1.el6 Available: nfs-ganesha-2.5.3-1.el7.x86_64 (ovirt-4.2-centos-gluster312) nfs-ganesha = 2.5.3-1.el7 You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest This host server also have hosted engine running on it. I am using local storage for hosted engine. Can any one help on above. Thanks Shashank

gluster shard size
by Alex McWhirter 24 Jan '20

24 Jan '20

building a new gluster volume this weekend, trying to optimize it fully for virt. RHGS states that it supports only a 512mb shard size, so i ask why is the default for ovirt 64mb?

Re: KVM (libvirt) VM Import
by jorgevisentini＠gmail.com 24 Jan '20

24 Jan '20

Hi Paul, thanks for your reply. I imported the VM with the command below, but I had that create a Export Domain on oVirt for this task. Only problem this task is that is in two parts, first part is export to Export Domain, on NFS, and second part is import on oVirt through of the Export Domain. This was the only way I managed to import. virt-v2v -ic qemu+ssh://root@10.255.255.23/system TEMPLATE-WINDOWS2019 -o rhev -os 10.255.255.22:/export --network TEMPLATE-WINDOWS2019 Thanks again.

API OVA export - getting job id/job status
by lars.stolpe＠bvg.de 24 Jan '20

24 Jan '20

hi, I tryed this with API 4.2 and 4.3. purpose of the following script is, to export a given list of vm as OVA one after another. To reach that i need to monitor the job status and pause the script till the actual export is done. The script works fine, but not the restriction of the returned jobs to the one spcificaly job i need to monitor. Therefor the script pauses on *any* running job. the working script: #!/usr/bin/python import logging import time import ovirtsdk4 as sdk import ovirtsdk4.types as types connection = sdk.Connection( url='https://ovirtman12/ovirt-engine/api', username='admin@internal', password='***', ca_file='/etc/pki/ovirt-engine/ca-ovirtman12.pem', ) hosts_service = connection.system_service().hosts_service() hosts = hosts_service.list()[0] vms_service = connection.system_service().vms_service() vms = vms_service.list(search='name=blxlic954') for vm in vms: # print("%s (%s)" % (vm.name, vm.id)) vm_service = vms_service.vm_service(vm.id) start_time = (time.strftime('%Y%m%d_%H%M%S', time.localtime(int(time.time())))) vm_service.export_to_path_on_host( host=types.Host(id=hosts.id), directory='/nfs_c3/export', filename=('%s_backup_%s.ova' % (vm.name, start_time)), wait=True, ) # time.sleep(5) jobs_service = connection.system_service().jobs_service() jobs = jobs_service.list(search='') for job in jobs: print(job.id, job.description) # job = jobs_service.job_service(job.id).get() while job.status == types.JobStatus.STARTED: time.sleep(10) job = jobs_service.job_service(job.id).get() print('job-status: %s' % (job.status)) connection.close() The line jobs = jobs_service.list(search='') works fine as long as the search pattern is empty. if i try to restrict the results returned like this: jobs = jobs_service.list(search='description=*blxlic954*') i get an error: bad sql grammar [select * from (select * from job where ( job id in (select distinct job.job id from job where ( ) )) order by start time asc) as t1 offset (1 -1) limit 2147483647]; nested exception is org.postgresql.util.psqlexception: error: syntax error at or near ")" looks like the 'where' clause is not filled correctly. Am i wrong with my syntax or ist that a bug? Is there another way to get the correct job id/status?

Hyperconverged solution
by Benedetto Vassallo 24 Jan '20

24 Jan '20

Hello Guys, Here at University of Palermo (Italy) we are planning to switch from vmware to ovirt using the hyperconverged solution. Our design is a 6 nodes cluster, each node with this configuration: - 1x Dell PowerEdge R7425 server; - 2x AMD EPYC 7301 Processor; - 512GB of RAM (8x 64GB LRDIMM, 2666MT/s, Quad Rank); - 2x Broadcom 57412 Dual Port 10Gb SFP+ ethernet card; - 3x 600GB 10K RPM SAS for the OS (Raid1 + hotspare); - 5x 1.2TB 10K RPM SAS for the hosted storage domain (Raid5 + hotspare); - 11x 2.4TB 10KRPM SAS for the vm data domain (Raid6 + hotspare); - 4x 960GB SSD SAS for an additional SSD storage domain (Raid5 + hotspare); Is this configuration supported or I have to change something? Thank you and Best Regards. -- Benedetto Vassallo Responsabile U.O.

Re: OVA export to NFS share slow
by Jürgen Walch 23 Jan '20

23 Jan '20

➢ I have a very similar setup as you and have just very recently started testing OVA exports for backup purposes to NFS attached storage. ➢ I have a three node HCI on GlusterFS (SSD backed) with 10Gbit and my ovirt management network is 10Gbit as well. My NFS storage server is an 8 x 8Tb 7200 RPM drives in RAID10 running CentOS 8x with 10Gbit link. Our setups are indeed similar, the main difference being, that my management network including the connection to the NFS server is only 1Gbit. Only GlusterFS has 10Gbit here. ➢ I haven't done specific measurement yet as I just setup the storage today but a test export of a 50Gb VM took just about ~10 minutes start to finish. Doing the maths this is ~80MiB/s and 20 times faster than in my setup. Lucky you 😊 Much less than your 10Gbit link between NFS Server and nodes could provide, but maybe close to the limit of the drives in your NFS server. The interesting thing is, that when setting up an export domain, stopping the VM and doing an export to the *same* NFS server, I'm getting write speeds as expected. Only the OVA export is terribly slow. The main difference I can see is the use of a loop device when exporting to OVA. The export to the export domain does something like /usr/bin/qemu-img convert -p -t none -T none -f raw {source disk on GlusterFS} {target disk on NFS server} whereas the OVA export will do /usr/bin/qemu-img convert -T none -O qcow2 {source snapshot on GlusterFS} /dev/loopX with /dev/loopX pointing to the NFS OVA target image. If you have the time and are willing to test, I would be interested in how fast your exports to an export domain are -- juergen
