OK, that makes sense. I think this is a bug in the server then. If the
users are not oVirt users we should just not report them, or maybe
report just the user name and domain, if available. But returning 404
and failing in that case isn't correct, in my opinion. I have opened the
following bug to track this issue:

  Don't fail with 404 if session user doesn't exist in the database

Great, thank you Juan.
My preference is for reporting username and domain, instead of not 
reporting at all.


Thank you again.

Thanks, that helps. What the engine isn't finding is the user, not the
virtual machine. Can you provide more information about that user? I
mean, take the virtual machine and find via the GUI which user is using
it. Then go to https://.../ovirt-engine/api/users and find that user.
Share the definition of that user that you get there, if possible.

Giulio, you should never get a 404 error from that URL, unless the
virtual doesn't exist or isn't visible for you. What user name are
you
to create the SDK connection? An administrator or a regular user?



I tried with a regular domain user (with superuser role assigned) and
admin@internal, with same result.


Also, please check the /var/log/ovirt-engine/server.log and
/var/log/ovirt-engine/engine.log when you send that request. Do
you see
there something relevant?


server.log reports:

(no surprise here, same message obtained by curl).

engine.log is full of:

It's quite strange I can perform almost every other operation (e.g.

Finally, please run your script with the 'debug=True' option in the
connection, and with a log file, like here:


https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/list_vms.py#L20-L37




Then share that log file so that we can check what the server is
returning exactly. Make sure to remove your password from that log
file
before sharing it.


Find attached produced log (passwords purged).

BTW: VM is a Fedora 24, with guest agents correctly installed (I

Re: [ovirt-users] Python-SDK4: How to list VM user sessions?

[Giorgio Biacchi]

Hi,
I'm taking over Giulio because he's not at work now. I'm starting to understand 
what's happening because we have not that users (and many others) in the users 
tab in the admin portal.


We have heavily modified the paradigm of ovirt, VM are bound to thin clients and 
not to users, this because we want to reproduce a lab/classroom environment and 
we don't use the user portal. We wrote an alternative administration portal 
where we define classrooms, thin clients and associations between clients and VMs.


Windows VMs are joined to a AD domain and linux VMs are joined to IPA, home dirs 
are remotely mounted upon user login.


So there's no need to have all that users (over 31000) in the admin portal 
because they have no permission on any VM, they can login from any client to the 
VM bound to that client.


In the admin portal, if I go to a VM with a logged in user in the "Guest info" 
tab I can see which user is logged in because, I think, the guest agents are 
aware of the logged in username, but there's no "user object" in the engine when 
I try to get that information via API.


Thanks for your time and patience..

Regards,
Giorgio

I have been trying to reproduce this and I wasn't able. In theory the
404 error that you get should only happen if the virtual machine doesn't
exist, but that isn't the case.

Can you check the server.log file and share the complete stack traces
that should appear after the "HTTP 404 Not Found" message?

Hi,
I'm trying to obtain a list of users connected to a VM, using python SDK

Here's what I'm doing:

vm = vms_service.list(search="name=vmname")[0]
vm_service = vms_service.vm_service(vm.id)
sessions = vm_service.sessions_service().list()

But "sessions" is None.

Same result using:

s = connection.follow_link(vm.sessions)

"s" is None.

I tried also using curl, and if I connect to:

https://my.ovirt.host/ovirt-engine/api/v4/vms//sessions

I get a beautiful 404.

Also using v3 of python SDK I obtain the same behaviour.

So I suspect that retrieving user sessions via API is not implemented,
is it? If not, what I'm doing wrong?

I'm using RHV 4.0.6.3-0.1.el7ev

Giulio, you should never get a 404 error from that URL, unless the
virtual doesn't exist or isn't visible for you. What user name are you
to create the SDK connection? An administrator or a regular user?



I tried with a regular domain user (with superuser role assigned) and 
admin@internal, with same result.



Also, please check the /var/log/ovirt-engine/server.log and
/var/log/ovirt-engine/engine.log when you send that request. Do you see
there something relevant?


server.log reports:

2017-03-31 10:03:11,346 ERROR [org.jboss.resteasy.resteasy_jaxrs.i18n] 
(default task-33) RESTEASY002010: Failed to execute: 
javax.ws.rs.WebApplicationException: HTTP 404 Not Found


(no surprise here, same message obtained by curl).

engine.log is full of:

ERROR [org.ovirt.engine.core.aaa.filters.SsoRestApiAuthFilter] (default 
task-7) [] Cannot authenticate using authentication Headers: 
invalid_grant: The provided authorization grant for the auth code has 
expired


(indipendently of my request)

It's quite strange I can perform almost every other operation (e.g. 
getting other VM parameters, running methods, etc.)





Finally, please run your script with the 'debug=True' option in the
connection, and with a log file, like here:


https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/list_vms.py#L20-L37

Then share that log file so that we can check what the server is
returning exactly. Make sure to remove your password from that log file
before sharing it.


Find attached produced log (passwords purged).

BTW: VM is a Fedora 24, with guest agents correctly installed (I can see 
user sessions in admin portal and in postgresql DB).


Thanks,
Giulio

Giulio, you should never get a 404 error from that URL, unless the
virtual doesn't exist or isn't visible for you. What user name are you
to create the SDK connection? An administrator or a regular user?

Also, please check the /var/log/ovirt-engine/server.log and
/var/log/ovirt-engine/engine.log when you send that request. Do you see
there something relevant?

Finally, please run your script with the 'debug=True' option in the
connection, and with a log file, like here:


https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/list_vms.py#L20-L37

Then share that log file so that we can check what the server is
returning exactly. Make sure to remove your password from that log file
before sharing it.

Works OK for me:

In [12]: vm_service =
vms_service.vm_service('55095f91-e8e3-4634-9d05-47e0cc91e66b')

In [13]: vm_service.sessions_service().list()
Out[13]: []

In [14]: sdk.version.VERSION
Out[14]: '4.0.4'


What is the version of the SDK you are using?

Yes, if I print vm I obtain:



while if I print vm_service:

VmService:/vms/

and it is a real service (e.g. I can call method start, shutdown, ...)

Hi Giulio,

I tried to reproduce your same steps and it returns an non-empty list
