[ovirt-users] VM - HDD vs SSD virtual disks

Hi, In Windows 11 VMs, virtual disks are reported as "HDD" whereas the underlying storage is SSD (ISCSI Storage Array). This may lead to unnecessary defragmentation and other "optimizations". Is there something to do to flag virtual disks as being "SSD" ? It is also detected as

[ovirt-users] virtio-scsi. SSD vs HDD

HI, Is there a way to set a disk as being SSD (which really is). Or, better, set an entire Storage Domain being SSD ? This would prevent the schedule optimization to be automatically ON in Windows. and maybe enable other underlying optimization (TRIM ?)

[ovirt-users] Shared and local storage, together

HI, We running some VMs from local storage. These are VMs for managing and monitoring tools such as Dell Storage Manager. So we don't want them to be stored in the shared storages they are managing and monitoring If something goes wrong on either the storage or the ISCSI network we want

[ovirt-users] Re: multiple hypervisors with local storage - template distribution

Hi, I'd say that Ansible scripts run from the manager are the way to go. We're doing export / import of OVAs from one local storage to another that way Exemple to export OVAs : - hosts: localhost connection: local become: yes become_method: sudo gather_facts: no vars:

[ovirt-users] Re: Ansible - export_ova

Hi, Good point, How did I missed that.. (Maybe should be rephrased to : "The name of the destination host who will execute the export".) * Laurent Duparchy ESRF - The European Synchrotron MIS Unit 04 76 88 22 56* Arik Hadas wrote on 15/10/2023 09:47: On Fri, Oct 13, 2023 at 3:11

[ovirt-users] Ansible - export_ova

We're using a script to export some VMs. This involves export_ova task - Is there a way to parallelize OVA exports (running on different hosts) ? When exporting to OVA from the GUI, we have to select a host, but ansible export_ova has no "hosts" parameter.

[ovirt-users] pass-through CPU

Hi, What are the pro and cons of enabling pass-through CPU ? It is a greyed option for a VM, unless specific host(s) is/are selected. That's the thing : it's possible to select all hosts..., so, it does not make difference w/ "Start on any host" option

[ovirt-users] Re: I would like to inquire about doing DR solutions Active-Passive.

Hi, Yes you need some sort of replication of your Storage Domains to be able to recover from a disaster. The more frequent replication, the less you'd loose. Storage arrays provide this feature natively and go as far as synchronous (real time) replication and automatic failover. So, oVirt

[ovirt-users] infrastructure boostrap. (i.e engine start / autostart).

Hi, We decided to run the oVirt engine (Oracle flavor) outside the infrastructure. (Medium infrastructure, 10 Hosts, iSCSI storage arrays) We created a second, smaller infrastructure (Single host, local storage) for management (engine) and monitoring (nagios, Dell storage manager etc..) . .
