Rename Virtual Machine
by lavi.buchnik＠exlibrisgroup.com
Hi,
We have this scenario:
- VM running Centos-7
- VM running Oracle-8
Then, we shutdown and delete Centos-7 VM (verified by API and UI)
Then, we rename Oracle-8 VM (via API) to have the name of the old Centos-7 VM and then stop/start Oracle-8 VM.
Rename is working and VM is coming up (status is "up" from API and also in the UI).
The problem is that Oracle-8 VM is not really up. it is hanging. not replying to PING nor to SSH.
Seems like the root cause is this:
- Oracle-8 VM name is indeed Centos-7 VM. but its FQDN (seen in UI) is still its Original name.
- So when getting both Centos-7 VM name and Oracle-8 VM name status, I get an answer (via API) about both of them:
Both reply with "up"
I'm using a simple API to rename the VM as followed (vm_name is Oracle-8 VM name, and new_name is Centos-7 VM name):
vm_id_obj = self.get_vm_id(vm_name)
updated_vm = vm_id_obj.update(
vm=types.Vm(
name=new_name
)
)
Thanks,
Lavi

VM disks Block device
by hemak88＠gmail.com
LVM is used underneath the storage domain for disk management in kvm cluster on ovirt. VG which is the storage domain is visbile and active in all hosts in the same datacenter on ovirt. But, LV under this vg (that is the virtual disks of vms) is not active and the corresponding block devices of these LVs is not available on all hosts in cluster.
I find only the running VMs LVs are active on the corresponding host. Is this a feature?
Is it possible to get a corresponding block device and LV on all hosts in cluster?

Resending with Log: Hosted Engine Deploy Fails at "Waiting for Host to be up"
by Angel, Christopher
I've installed 3 Ovirt Nodes and am trying to set up the hosted engine. Every time I run it however, it fails at the 'Waiting for host to be up' stage. I've attached the relevant log.

Ovirt Error after creating a VM image
by lavi.buchnik＠exlibrisgroup.com
Hi,
I wrote an automation that provisioning a VM using ovirtsdk4 (we are using Ovirt 4.3).
In the last week, we notice that sometimes the VM provisioning is failing with this error:
"The response content type 'text/html; charset=iso-8859-1' isn't the expected XML"
This error is happening when the automation is creating the VM image and waiting for its status to get change from "image-locked", this to be able to set affinity on it and later to start the new VM.
So the error is happening while the image is in "image-locked" state.
Can you please let me know why it is happening (note that it is occurring like 1 out of 4 attempts) and how can it get fixed?
Thanks,

Unable to add more than 16 vCPUs to running VM
by David White
I have a fully patched / up-to-date engine:
Software Version:4.5.4-1.el8
And a fully patched, up-to-date host.
[root@cha3-storage dwhite]# yum info ovirt-hostLast metadata expiration check: 1:33:40 ago on Sun 04 Jun 2023 09:28:39 AM EDT.
Installed Packages
Name : ovirt-host
Version : 4.5.0
Release : 3.el8
Architecture : x86_64
Size : 11 k
Source : ovirt-host-4.5.0-3.el8.src.rpm
Repository : @System
From repo : centos-ovirt45
The host has 32GB of RAM, and there's only 1 VM on this host.
When I try to add more CPUs to the VM from the manager UI, I get the following error:
- The requested number of vCPUs is not available on the host the VM is running on
What's going on here, and why can I not add more vCPUs to this VM?

oVirt 4.4 - Integrate event notifications with System Center Operations Manager
by angus＠ajct.uk
Hello
I am looking to integrate oVirt 4.4 event notifications with an incident management tool - M$ System Center Operations Manager.
I need to give examples to SCOM of what an unhealthy email looks like and what a recover/healthy email looks like for each event I want it to manage.
Is there a way of triggering sample notifications (something failed/something recovered) for events or perhaps I can see the email templates used somewhere? (I did try a grep -Hr on the engine VM for "alertMessage" and "resolveMessage" for a VM migration notification but only found an entry in the in the notifier log.
Thanks

Regarding oVirt IP Address Change
by Pro Cloudguru
Hello oVIrt Community,
Presently, I've a healthy & running oVirt Hosting that includes single DC,
Cluster, SPM & Storage. The LAN IP Address range is 10.151.65.0/24.
As we're in the process of migrating office premises, I'm worried about the
existing oVirt IP Address Schema as the new range is 10.101.160/0/20.
In this scenario, I'd like to know how the migration happens successfully
without disturbing the oVirt Hosting & all hosted VMs.
Please Guide,

Hi guys.
I'm revisiting my failed attempt to make friends with oVirt

Deployment fails sooner that what can troubleshoot - at
least I manged to find in docs so far - and I wanted to ask
hot to troubleshot such failure as this:

I think that last two snippets-blocks, might be most useful
- but what does it says?
When 'installer' is finished, there is no aforementioned
pool however there is:
-> $ virsh pool-list | grep
'9ab14cca-78e0-4a8e-8a1b-00e98c300208'
9ab14cca-78e0-4a8e-8a1b-00e98c300208-1 active yes
Engine VM remains is up & running,
How far from successful deployment that is & what would be
advised to do next?
many thanks, L.
