Find MAC for VM

Hi all I've got the following Python snippet which works fine under 4.3 but I need it to work under 4.1 as well. --- nics_service = vms_service.vm_service(vm.id).nics_service() nic = nics_service.list(search='name=nic1')[0] --- Under 4.1, it barfs on "nics_service.list(search='name=nic1')[0]". What do I need to do to make it work under 4.1? Thanks

ISO domains are deprecated. I guess you can upload to regular data domains.

ovirt-imagio-proxy upload speed slow
by Dev Ops 18 Sep '19

18 Sep '19

I am working on integrating a backup solution for our ovirt environment and having issues with the time it takes to backup the VM's. This backup solution is simply taking a snapshot and making a clone and backing the clone up to a backup server. A VM that is 100 gig takes 52 minutes to back up. The same VM doing a file backup using the same product, and bypassing their rhv plugin, takes 14 minutes. So the throughput is there but the ovirt imageio-proxy process seems to be what manages how images are uploaded and is officially my bottle neck. Load is not high on the engine or kvm hosts. I had bumped up the Upload image size from 100MB to 10gig weeks ago and that didn't seem to help. [root@blah-lab-engine ~]# engine-config -a |grep Upload UploadImageChunkSizeKB: 10240000 version: general [root@bgl-vms-engine ~]# rpm -qa |grep ovirt-image ovirt-imageio-proxy-1.4.6-1.el7.noarch ovirt-imageio-common-1.4.6-1.el7.x86_64 ovirt-imageio-proxy-setup-1.4.6-1.el7.noarch I have seen bugs reported to redhat about this but I am running above the affected releases. engine software is 4.2.8.2-1.el7 Any idea what we can tweak to open up this bottleneck?

Yes. But check SELINUX and DAC permissions.

We use Active-Active Hp XP replication between 2 DCs for our VmWare Clusters. I guess you can use the same replication for oVirt or even Hyper-V.

Is GFS/GFS2 supported by oVirt as shared storage?

FW: user role

Hi Kim, If you add them to a group in AD then add the users and group to oVirt you can add the permissions to the group. Then add the VmCreator and DiskProfileUser to the Datacenter. Add the UserTemplateBasedVM permission to any templates you want them to be able to use Add the VnicProfileUser permission to any vNIC profiles they should have access ( make sure public isn't enabled on any vNIC profiles you don't want them to have access to) When they create a VM they will then get UserVmManager permission and the DiskOperator permissions on any disks. This means they should be able to do all 1 to 8 for their own VMs and also delete their VMs and Disks.

Changing ISO domains
by Mark Steele 17 Sep '19

17 Sep '19

Hello, I recently removed our ISO domain from out cluster (oVirt Engine Version: 3.5.0.1-1.el6) because it was on a storage location we no longer want to use. I am now not clear on how to add the new ISO domain in. I created a new ISO domain type via storage and pointed to an NFS share on the new storage, however it does not behave as I anticipated (I cannot see ISO's when creating new VM's) I suspect I missed a step - how are new ISO domains added to a cluster?

Disaster recovery active-active question
by wodel youchi 17 Sep '19

17 Sep '19

Hi, On the active-active DR, in the documentation it is said : "You require replicated storage that is writeable on both sites to allow virtual machines to migrate between sites and continue running on the site’s storage." I know that it's not a direct oVirt question, but if someone has implemented this ... Which type of storage that can offer both real time synchronization and read/write on both ends on the replicated volumes? Regards.

Re: the virtual machine crushed and I cant shutdown the vm successfully
by Strahil 17 Sep '19

Have you checked the Hypervisor's logs. I would start with logs from libvirt and vdsm (host) and then the logs on your engine. What OS is your VM and the version of the VM itself (you can check in the UI).
