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.

--nodigest My understanding is all the dependencies should be in the ovirt repository. Also, the repos point to fc$release server. I change the fc to el$releaseserver before it even works. What did I miss? Eric Evans Digital Data Services LLC. 304.660.9080

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

by jorgevisentini＠gmail.com 23 Jan '20

23 Jan '20

Hi all! I have a Suse KVM and I would like to import all VMs to oVirt. There is a easy mode to make it? I am try to import with Compute -> Virtual Machine -> Import. I can visualize the VMs but its show me the error when I try import: "libvirtError: Storage volume not found: no storage vol with matching path '/VMs01/VM/disk.qcow2" Anyone can help-me please?

Gluster storage options
by Shareef Jalloq 23 Jan '20

23 Jan '20

Hi there, I'm wanting to build a 3 node Gluster hyperconverged setup but am struggling to find documentation and examples of the storage setup. There seems to be a dead link to an old blog post on the Gluster section of the documentation: https://www.ovirt.org/blog/2018/02/up-and-running-with-ovirt-4-2-and-gluste… Is the flow to install the oVirt Node image on a boot drive and then add disks for Gluster? Or is Gluster setup first with ovirt installed on top? Thanks.

Disconnecting drive from VM
by anthonywest＠alfatron.com.au 22 Jan '20

22 Jan '20

Hi! For a Virtual Machine that is already shutdown, does anyone know if I can detach a disk from the VM, export the remaining parts of the VM, then reattach the disk without causing any problems with the software installed in the VM? Thanks, Anthony

Memory problem
by Stefan Wolf 22 Jan '20

22 Jan '20

Hi to all, I ve a memory problem I got this error: Used memory of host kvm380.durchhalten.intern in cluster Default [96%] exceeded defined threshold [95%]. after reviewing the server with top command, I found ovn-controller with heavy memory usage: 45055 root 10 -10 46,5g 45,4g 2400 S 51,3 72,4 627:58.60 ovn-controller after restarting ovn-controller, every thing is fine again. after some days, it uses so much memory again. I ve also tried to wait a day or two, after that it seems to restart it self. is there a solution that ovn-controller does not use so much memory or restart automatic? thx shb

Re: possible to export a running VM to OVA?
by Jürgen Walch 22 Jan '20

22 Jan '20

Shutting down the VM during the export will give you a fully consistent state of the VM whereas snapshots without further help from the VM itself will only provide "crash consistency", that is provide you with a disk image equivalent to one where the power cord was plugged out of the running machine, which is usually, but not always consistent enough :) BTW: As far as I understand the OVA export run from the engines web-gui *is* also doing a snapshot. You can see the snapshot if you have a look at the VM's disks while the export is running. -- juergen
