I've made some progress, the Hosted Engine Storage Domain was

Now oVirt tries to import the Hosted Engine VM, but fails with a

[ovirt-users] Re: aggregate multiple hosts

2023-01-13 Thread Guillaume Pavese 
Hi,

Running a vm sharing compute resources from multiple nodes is not possible.
Moreover, Intel E8400 processors are too old, and not supported since oVirt
4.3

Best regards,

I am glad it helped. Unfortunately, I do not know what could have caused

If you want to aggregate hardware capabilities to an unique VM, i.e. 
vcpu from multiple hosts or RAM aggragation, I don't think it is 
possible, but I may be wrong... some other members of the  community may 
confirm.

Sparsify-image is not disabled, it can still be invoked on raw volumes.

Yeah, pass-discard could be an option if your underlying storage supports
it.
You can read more about it in the original feature page:
https://www.ovirt.org/develop/release-management/features/storage/pass-discard-from-guest-to-underlying-storage.html
But as I previously wrote, sparsifying the image without going through
ovirt-engine (but let's say, with the VDSM API) is also an option if you
don't care about the reduction in size not being reflect in oVirt

I would suggest to concentrate on the issue above - if the image is set
with illegal state or locked at the end of the process, it means the upload
operation didn't finish successfully and the issue below is likely a
consequence of having an invalid image

[ovirt-users] Re: Slightly confused by KeyCloak

2023-01-13 Thread Artur Socha 
Hi Theo,
The thing you mentioned - ovirt-administrator groups is a special construct
with a  purpose of having bootstrapped ovirt admin user for the new oVirt
installations. This explains why Keycloak users assigned to that group, can
for example, create new VMs.

Keycloak server bundled into oVirt setup serves only authentication purpose
as opposed to the authorization, therefore, it is not required to create
Keycloak group 'ovirt-student' and match it with oVirt counterpart.
If I understood correctly - users defined in keycloak can actually login to
oVirt Admin panel and/or to ovirt vm portal, right?
If that's the case - you're simply missing some (group?) permissions -
these permissions are only managed from within oVirt admin panel.
One more thing worth mentioning. In order to have some users under group
defined  in oVirt (via admin panel) you have to manually assign them
there.  User & group association defined in Keycloak is not propagated to
oVirt. Although, it could be a nice feature to have!

Perhaps this documentation will help a bit:
https://www.ovirt.org/documentation/virtual_machine_management_guide/index.html#sect-Virtual_Machines_and_Permissions

cheers!
Artur
