I saw notes about oVirt 4.4 may no longer support ISO images... but there are times like now I need to build based on specific ISO images. I tried to do a cycle to create an image file 8GB then do dd if=blah.iso of=/<random disk ID image file name> Created a new vm with this as boot disk and it fails to boot... so.. back to "create volume for iso images" But when I do that I get error New Domain -> "Domain function" =iso Storage type = glusterFs Use Managed Gluster volume -> Select already working gluster file space "thor.penguinpages.local:/iso VFS Type: glusterfs mount options: backup-volfile-servers=odin.penguinpages.local:medusa.penguinpages.local Error: Error while executing action: Cannot add Storage Connection. Performance o_direct option is not enabled for storage domain. Questions: 1) Why did the image and dd of iso to boot disk not work? 2) Any ideas about create of iso mount volume? -- penguinpages

4.4 supports iso images of course. The note is about ISO storage domain - this is a special storage domain that can be created only on NFS, and can hold only ISO images. To add ISO images to this special storage domain, you had to use a special iso uploader program, or add manually to the right place in the storage domain directory, and make sure the permissions are correct. This storage domain type was deprecated several version ago, but it is still available. Since 4.2 (or maybe even before that) you can upload ISO images to data domain of any type (e.g. NFS, Gluster, iSCSI, FC). Upload is available via the administration portal, or via the API/SDK, same as other image types. Note that there is an issue on block storage data domain, preventing changing CD on a running VM. We are working on fixing this for 4.4.3.

I'm not sure what you tried to do.
But when I do that I get error
New Domain -> "Domain function" =iso Storage type = glusterFs Use Managed Gluster volume -> Select already working gluster file space "thor.penguinpages.local:/iso VFS Type: glusterfs mount options: backup-volfile-servers=odin.penguinpages.local:medusa.penguinpages.local
Error: Error while executing action: Cannot add Storage Connection. Performance o_direct option is not enabled for storage domain.
Your gluster volume is not configured properly for ovirt. Did you add the volume via the administration portal? Why do you need special gluster volume for ISO images?
Questions: 1) Why did the image and dd of iso to boot disk not work?
We don't have enough information here to tell.
2) Any ideas about create of iso mount volume?
Yes: 1. Visit Storage > Disks 2. Click Upload 3. Select ISO image 4. Select storage domain to upload the image 5. Click "Upload" Nir

Might I suggest that you folks revisit the issue of what to do with the "guest tools iso". Since supposedly they are, "provided by the oVirt-guest-tools-iso package installed as a dependency to the oVirt Engine. This ISO file is located in /usr/share/oVirt-guest-tools-iso/oVirt-tools-setup.iso on the system on which the oVirt Engine is installed." https://www.ovirt.org/documentation/vmm-guide/chap-Installing_Windows_Virtua... (the package is no longer an automatic dependancy either. at least for hosted-engine)

Maybe it is not needed now? How did you use this ISO before? uploaded it to ISO domain?
well, I havent used it before :) I just discovered that some windows VMs of ours needed guest additions, and looked for the right way to handle it for ovirt. OH. I think you are implying perhaps that modern windows VMs automatically have hooks for virtual hosting? Sad to say, these are ...

I don't know how the windows guest tools are shipped now, but Gal should know. If you have this ISO, you can upload it to some data domain. After that you can attach it to any VM.

The Windows VM guest agents and drivers are a part of the virtio-win package, you can install the RPM which will contain the ISO or download the iso directly from: https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-vir... The iso contains an exe that will install all that is needed, just make sure to mark option->install ovirt guest agent

That sounds rather important to know, thank you. Seems like the docs at https://www.ovirt.org/documentation/vmm-guide/chap-Installing_Windows_Virtua... reaaaally need some serious updating. For example, they do also mention virtio-win.vfd .... but say that gets added to "The default storage domain", which you folks just said is deprecated. So there needs to be a non-deprecated way spelled out of getting these things? Im not sure where to get that vfd now either. I successfully did a "yum install virtio-win" ... however, the contents of the package do not seem to contain "virtio-win.vfd". Ahhh.. again, the documentation needs to be updated. There is no "virtio-win.vfd", in the package, but there IS /usr/share/virtio-win/virtio-win_amd64.vfd /usr/share/virtio-win/virtio-win_servers_amd64.vfd /usr/share/virtio-win/virtio-win_servers_x86.vfd /usr/share/virtio-win/virtio-win_x86.vfd ----- Original Message ----- From: "Gal Zaidman" <gzaidman@redhat.com> To: "Nir Soffer" <nsoffer@redhat.com> Cc: "Philip Brown" <pbrown@medata.com>, "Jeremey Wise" <jeremey.wise@gmail.com>, "users" <users@ovirt.org>, "Arik Hadas" <ahadas@redhat.com> Sent: Thursday, September 24, 2020 12:39:00 AM Subject: Re: [ovirt-users] Re: ISO Repo On Wed, Sep 23, 2020 at 8:48 PM Nir Soffer <nsoffer@redhat.com> wrote:

This is close to all i need. I did upload the iso as image.. but how do you attach it to the VM ? I assumed that issue was a 4.4 changes / constrain. It was a miss-interpretation on my part that ISO use was relegated to being only as a "volume" independent. As such.. I went back to uploading iso images. They are now "images" in disk. Going to VM: select vm -> Disks -> VM Devices -> "edit virtual machine" -> Boot Options -> "attach CD" -> "whoot!!!" ISO images now show as attachable option. Thanks.. All good.
