The fix should be contained in recent oVirt relases.

Cannot delete snapshot
by Giulio Casella
Hi,
I'm having (another) issue working with snapshots.
Since a few days my backup system (storware vprotect) cannot delete a
snapshot. Message reported by SPM is:
HSMGetAllTasksStatusesVDS failed: value=Volume does not exist:
('6180c2e8-141a-4126-bcb1-5af5caa98175',) abortedcode=201
Other snapshots from other VMs are working fine (created and deleted as
needed).
I verified it, I can reach on SPM filesystem other snapshots from the
same VM, but that one doesn't exist.
I suspect that during normal backup management that snapshot has been
correctly removed from file system, but still live in ovirt database.
I'm pretty sure vProtect use ovirt API to operate, it doesn't directly
interact with ovirt database. That's why I'm talking to you and not to
storware guys.
Is there a (safe) way to get rid of that snapshot?
TIA
Regards,
Giulio Casella

Re: Ansible ovirt.ovirt_vm nics
by Matthew.Stier＠fujitsu.com
I believe I have identified the issue, variable inheritance.
The inventory I include to define the hosts, includes several classes. ‘virtualmachines’ which the script uses to get the list of VMs it is going to process. All VM defaults are defined within its ‘:vars’ section.
I also have groups of VMs where I want to override variables. Unfortunately, what is being defined in ‘virtualmachines’ is not being override in the class level, because they are considered sibling classes.
I have found the ‘ansible_group_priority’ variable, which can be assigned at each class. I assigned the entry in [virtualmachines:vars] with the value of 2 (default is 1) and then in the other classes, I assigned a value of 3.
Now the variable in [class:vars] will override the variables in [virtualmachines:vars]. Of course the host level can still override all.

Subject: [ovirt-users] Re: Ansible ovirt.ovirt_vm nics
It’s basically the one listed in the URL. The changes I’ve made is to add some addition ‘defaults’, and the code I mentioned below, to select different nic profiles for vms that are on different networks.
I’m running an Oracle Linux 7u9 system, and the version of Ansible is 2.9.18
In my environment, I have created different networks, and labeled them based upon their vlan tag number (vlan20, vlan21, vlan22, …)
A VM can be created on any of these vlans, so I need to be able to select the nic profile within ‘ini’ file holding all the configuration information. (hostname, fqdn, IP address, etc…)

Hi Matthew,
Could you please share with us your playbook? Which ansible version are you using? Are you using ovirt_vm module from oVirt Ansible Collection which contains newer versions than the ovirt_vm module included in Ansible 2.9?
https://docs.ansible.com/ansible/latest/collections/ovirt/ovirt/ovirt_vm_...
Thanks,
Martin

The ‘nics’ section of ovirt_vm is vague and with nearly no examples.
My playbook is based upon https://blogs.oracle.com/scoter/ansible-with-oracle-linux-virtualization-...
I’ve made several modifications, (more default) and added a few lines, which I believe is supposed to assign vnic profiles to the primary vnic (nic1), based upon the definition of ‘vm_nic1_profile’ defined in an included ‘ini’ file. (the profile defaulting to blank if it is not defined in the ini file.)
It isn’t doing its job.
nics:
- name: “nic1”
profile_name: "{{ hostvars[item]['vm_nic1_profile'] | default('') }}”
The playbook runs without complaint. If I run it with option ‘-vvv’ part of the output lists the variables, but the ‘nics’ variable is an empty list (nics[])
Any hints on what I’m doing wrong? I’ve checked the forum, but it tends to strip leading spaces, which is bad for indent sensitive code.

HCI - oVirt for CEPH
by penguin pages
I have been building out HCI stack with KVM/RHEV + oVirt with the HCI deployment process. This is very nice for small / remote site use cases, but with Gluster being anounced as EOL in 18 months, what is the replacement plan?
Are their working projects and plans to replace Gluster with CEPH?
Are their deployment plans to get an HCI stack onto a supported file system?
I liked gluster for the control plan for the oVirt engine and smaller utility VMs as each system has a full copy, I can retrieve /extract a copy of the VM without having all bricks back... it was just "easy" to use. CEPH just means more complexity.. and though it scales better and has better features, it means that repair means having critical mass of nodes up before you can extra data (vs any disk can be pulled out of a gluster node, plugged into my laptop and I can at least extract the data).
I guess I am not trying to debate shifting to CEPH.. it does not matter.. that ship sailed... What I am asking is when / what are the plans for replacement of Gluster for HCI. Because right now, for small sites for HCI, when Gluster is no longer supported.. and CEPH does not make it... is to go VMWare and vSAN or some other total different stack.

Re: Attempting to detach a storage domain
by Matthew.Stier＠fujitsu.com
Problem solved.
I used Ansible and ran 'grep Duplicate /var/log/vdsm/vdsm.log' on all 121 of my hosts. Only the log of the host currently running the hosted-engine had entries.
I migrated the hosted-engine, and all other VMs to other hosts, and then put the affected host into maintenance. I then undeployed it; then patched it; and finally deployed it.
Its back up and running and taking VMs, and no more 'Duplicate keys' errors.

I think engine.log would be a good place to start, it would likely
tell us on which host there's a problem (if there is one)

How to reduce load during create VM

Hi everyone, please, can you limit the "Create VM" process somewhere so that setting up quota does not load the server so much, especially storage when duplicating the template disk?

oVirt on GCP
by mario.gandara＠gmail.com
Hello, guys!
I'm trying to deploy oVirt on GCP for the last two weeks.
Someone did it on GCP using nested virtualization?
My scenario is:
One standalone oVirt Engine and two hosts.
In the future I imagine to scale this solution.
Thank you.
