Windows VirtIO drivers
by Shareef Jalloq 25 Mar '20

25 Mar '20

Hi, it seems the online documentation regarding the windows installation steps is well out of date. Where is there any current documentation on where to get the VirtIO drivers for a Windows installation? From a bit of Googling, it seems that I need to 'yum install virtio-win' on the engine VM and then copy the relevant .iso/.vfd to the ISO domain. Is that correct? Where is the documentation maintained and how do I open a bug on it? Thanks, Shareef.

Important notes before you try it Please note this is an Alpha release. The oVirt Project makes no guarantees as to its suitability or usefulness.

If you want to have a better experience you can test oVirt 4.4.0 Alpha on Red Hat Enterprise Linux 8.2 beta. Known Issues - After installation open the Default cluster and hit “Save”, for any other new Cluster using CPU autodetection the dialog needs to be explicitly saved after the detection happens, after first host is added. (bug https://bugzilla.redhat.com/1770697) Installation instructions For the engine: either use appliance or: - Install CentOS Linux 8 minimal from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps 389-ds - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… ; select minimal installation - dnf config-manager --set-enabled PowerTools - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - Attach the host to engine and let it be deployed.

Migrate Hosted Engine to new Storage
by Anton Louw 25 Mar '20

25 Mar '20

Hi Everybody, Does anybody know when we will most likely be able to do a live storage migration of the Hosted Engine? I've been battling with the backup and restore way for a couple of days now already, and it is starting to feel like a fruitless exercise. Thanks Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

does SPM still exist?
by yam yam 25 Mar '20

25 Mar '20

Hello, I heard some say SPM disappeared since 3.6. nevertheless, SPM still exists in oVirt admin portal or even in RHV's manual. So, I am wondering whether SPM still exists now. And could I know how to get more detailed information for oVirt internals?? is the code review the best way?

Data Center, Cluster and Storage Domains show as "Down" after backup and restore
by anton.louw＠voxtelecom.co.za 24 Mar '20

24 Mar '20

Hi Everybody, So I did a full backup of our HE, redeployed and restored. After the restore, I ran engine-setup on the newly deployed HE. I can access the the environment as per normal, the only issue is that everything still shows as "down", this includes hosts and VMs? Is there something I need to do in order to get everything to display as "Up" again? Thanks

storage allocation of template
by yam yam 24 Mar '20

24 Mar '20

Hello, I want to know whether a base disk image is physically copied whenever the VM is created from a template. I've just created a VM based on template with 1 disk and checked VM's virtual disk images. there were (1)base image copied? from the template, (2)new delta image. Here, (1) image was identical to that of the template and I know that image is used as read-only mode. So, I am wondering why base (disk) image is inefficiently copied instead of directly referencing template's image as backing file.

safe to have perf and dstat on ovirt node?
by Gianluca Cecchi 23 Mar '20

23 Mar '20

Hello, I would need to have on ovirt node these three packages: - ipmitool - perf - dstat Comparing latest RHVH (4.3.8) and latest ovirt-node-ng (4.3.9) I see that: - ipmitool is present on both - perf is present as an installable package in RHVH and not in ovirt-node-ng - dstat is not available in any of them Why the difference about perf? Is it safe to install perf and dstat on ovirt-node-ng taking them from CentOS updates? This is for a lab and the packages would be used to compute some metrics about performance of the node. Thanks, Gianluca
