Just a question from curiosity. Can't we just define second cluster and move each VM from old cluster to the new one ?

How do I do bridged networking?
by m.skrzetuski＠gmail.com 06 Jan '20

06 Jan '20

Hello everyone, how do I set up bridged networking? I want to give my VMs direct access to the network, that is: they should get an IP from DHCP and appear as "normal" nodes. This is working out of the box for Proxmox. I was not able to find documentation that would make it possible to configure. Can I configure it via https://github.com/oVirt/ovirt-ansible-infra? Kind regards Skrzetuski

Usage statistics or graph for an oVirt environment?
by Victor Hooi 06 Jan '20

06 Jan '20

Hi, Is there an easy way to generate a dashboard or some kind of graph to track the usage of an oVirt environment? This would be things like how many VMs were created, or started, how many successful logins, how many clones etc. (Use case is to justify an internal environment/use case) Thanks, Victor

Having an issue with Ovirt. Ovirt Engine server died. I have no idea about Ovirt and I am way over my head here. Trying to put the engine back together to get my environment working again. Can anyone help me here? Thanks in advance.

I setup my VMs to use the ovirtmgmt network as it is defined for all kinds of traffic. As you use Intel NUC - just create a VM manually with ovirtmgmt and if it works - check the ansible playbooks.

Re: Power management and storage domains error when running Ansible tasks!

If you have some kind of ethernet-controlled power plug - you can have fencing (at least I have considered that). Or you can edit the Host and disable the power management at all.

You need to speciify the method to be used for power fencing - that could be HPE's iLO, Dell's iDRAC, APC UPS or something else.

Hi Roy > To make this change, I assume the process would be to turn off all VMs, set cluster cpu type to broadwell, then turn on VMs to get the new CPU flags? Exactly, you can only reliably change the CPU type for a cluster once the last Westmere-based host is gone. That's what I had to do when I when we upgraded CPU microcode on clusters to enable the various CPU mitigations within the guests. After changing the CPU type at the cluster level, you should see an orange triangle shown with each VM in the Web UI indicating what VM needs a restart in order to pick up the change. Because of those various updates to CPU microcodes, check your current BIOS/UEFI (though microcode is part of CentOS/RHEL) then check the CPU Type in the tab of each Broadwell-based host. As of writing, ideally set "Intel Broadwell IBRS SSBD MDS" (or the -noTSX) variant. Regards Mathieu

Cluster CPU type update
by Morris, Roy 04 Jan '20

Hello, I'm running a 4.3 cluster with 56 VMs all set to default cluster and the cluster itself is set to Intel Westmere Family. I am getting a new server and retiring 3 old ones which brings me to my question. When implementing the new host into the cluster and retiring the older hosts. I want to change the CPU type setting in the cluster default to Broadwell which is what my new 3 host cluster will be. To make this change, I assume the process would be to turn off all VMs, set cluster cpu type to broadwell, then turn on VMs to get the new CPU flags? Just wanted to reach out and see if someone else has had to go through this before and has any notes/tips. Best regards, Roy
