The page where an exception is seen

Description of problem:
I try to create virtual machine and Disk for it from ovirt web interface. I set up Disk parameters and receive error.

Steps to Reproduce:
1. Start creating new virtual machine
2. In the message box with parameters for new virtual machine, press button "+" and "Create" to add new Disk.
3. Fill in all the necessary parameters of the Disk in the new message box as seen in the screenshot and press "Ok".

Actual results:
I see an exception in the web interface.

Expected results:
The Disk is created successfully.

Additional info:
There was a virtual machine with the same name before and there was a Disk with that same name.

Thanks for the report.

Can you please install the GWT symbol maps, reproduce again, and attach the new ui.log?

yum install ovirt-engine-webadmin-portal-debuginfo ovirt-engine-userportal-debuginfo

ui.log will then have a deobfuscated stack trace that can point us in the right direction.


Not sure if it's related, but in engine.log, I see:

New error message box

I had to update packages on the server, because of this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1415808

Now I receive Internal Engine Error after I try to create virtual machine itself (this time there is no error when creating disk image).

I will attach logs in the next comment (because, for some reason I cannot attach several files at the same time).

Internal Engine Error logs

The logs on the ovirt-engine host after getting Internal Server Error.

I have executed the command 'yum install ovirt-engine-webadmin-portal-debuginfo ovirt-engine-userportal-debuginfo' and restarted the server before trying to create virtual machine.

Comment 5 Egor 2017-01-27 12:48:55 UTC
Now it looks like I cannot create any virtual machine (even without creating disks). The logs above are still relevant.

Python script log

I've tried to create virtual machine with the following script: https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/add_vm.py

And I get the same error:
DEBUG:root:    <detail>[Internal Engine Error]</detail>
DEBUG:root:    <reason>Operation Failed</reason>

Comment 7 Greg Sheremeta 2017-01-27 14:32:47 UTC
I see the following in engine.log that explains why your create VM is failing:

2017-01-27 14:38:55,060 ERROR [org.ovirt.engine.core.bll.AddVmCommand] (default task-19) [] Exception: org.springframework.dao.InvalidDataAccessApiUsageException: Required input parameter 'v_guest_mem_free' is missing

Assigning to virt team for investigation.

Comment 8 Shahar Havivi 2017-02-01 08:39:39 UTC
Hi Egor,

as I see in the engine.log you an error regarding 'v_guest_mem_free' db field which is removed.
We cannot reproduce your error in several environments.

What exactly is the problem you encounter?
You cannot add disk at all?
Can you test a different setup?

Comment 9 Tomas Jelinek 2017-02-01 10:16:30 UTC
also, what is the exact version of your engine please? Where did you get it from?

Requested data for bug

Files 'action_1.png', 'action_2.png', 'action_3.png' depict the actions that lead me to internal server error.

Where do I get ovirt from?
First, I have downloaded an image from ovirt.org.
After that in a different bug I was asked to update my version of ovirt by performing command: 'dnf update ovirt-engine'.
That is all I did what could affect ovirt version of ovirt binaries.
In the file 'ovirt-version.txt' you can look at the version of all of the packages that I have.

In the folders 'ovirt-*' there should be all of the log files necessary to determine the cause of the problem (if you log enough info).

Comment 11 Tomas Jelinek 2017-02-03 19:38:07 UTC
hmm, and did you run engine-setup after running dnf update? because engine-setup updates your database and the symptoms here look like the DB is not updated.

No, I didn't run 'engine-setup' after 'dnf update'. But now, after did it, everything is working. I am sorry for taking your time, but this wasn't obvious for me.

Thank you!
