[ovirt-users] Re: Booting VMs from RHEL ISOs fail

[Yedidyah Bar David]

I finally got this to work.
I believe that my issue was that when I thought I had uploaded the ISO,
the ISO wasn't actually being uploaded successfully.
I tried to upload various ISOs to different Storage Domains, and
eventually noticed that in a couple of cases, I would see a status bar that
slowly incremented over time indicating the percentage of the upload
complete - whereas before, there would be no status bar, and the oVirt
Manager would indicate that the ISO had just been uploaded completely.

But you got no actual error anywhere? I'd consider this a bug. Would you
like to report one in bugzilla? Thanks!

Some points to test/include in your report:

Do you use an external certificate for https?

If so, did you follow the documented procedure to do this? Perhaps you can
tell the exact steps you took?

I'd still expect some error - so there are perhaps (at least) two separate
issues here.

I was able to "replicate" this status bar with the RHEL ISO, and now my VM
is booting to that ISO fine.

Perhaps you can tell what you did differently for this?

Thanks for the report.

Best regards,

yes, definitely a bug. If you managed to reproduce and file a bug for it,
besides standard logs (engine and vdsm logs), please provide also ovirt-
imageio log (from engine as well as from host), which can be found in /var/
log/ovirt-imageio/daemon.log

Thanks!

As far as I remember a feature was introduced that allows the end-user to
verify the disk checksum after an upload. Most probably it's not integrated
in the WEB UI, but the API should have it.

correct, here are examples/script how to compute checksum for image and uploaded disk:

https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/checksum_image.py
https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/checksum_disk.py
