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"
