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.
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 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"
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
