Re: Upgrade from 4.3.5 rc5 to 4.3.6 rc5 strange errors
by Strahil
Hm... It seems that I missed the complain about libibverbs.so.1 which is part of package libibverbs-22.1-3.el7.x86_64 .
Once I have deployed that, no more issues are observed.
I guess there is a missing dependency.

no hosted engine deploy while adding new host (oVirt 4.3.5)
by lars.stolpe＠bvg.de
I tryed to add a new host to my oVirt environment. I remember a checkbox whether the engine HA wil depoyed or not in oVirt 4.1.
Now the environmentist oVirt 4.3.5. In the add host dialog windows I cant find that option anymore. In edit window after host installation ther ist also no hosted engine tab.
hosted-engine --deploy don't ask, if it is an additional host (like it used to in 4.1), so it will install a new engine instead of depoying the existing engine.
Is there a new way of depoying the engine HA to additional hosts?

Find MAC for VM
by Colin Coe
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

Re: Changing ISO domains

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

ovirt-imagio-proxy upload speed slow
by Dev Ops
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.

Re: Disaster recovery active-active question
by Strahil
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
by Staniforth, Paul
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
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?
Mark
