Sparsifying VM disk not working
by andreas_nikiforou＠hotmail.com
Hello,
i cannot get sparsifying to work in lastest oVirt 4.5.4 release (not that i have tried with a previous release)
I have two Data domains connected to oVirt using iSCSI & NFS.
I created 2 testvm's and 50GB thin provisioned qcow2 disks for each, made some temp files, remove them and tried to sparsify, but it does not work.
Error i am getting is:
Error while executing action: Cannot sparsify Virtual Disk. Sparsifying is not supported for QCOW2 disk testvm1_Disk1.
In virtual disk options i have enable, Bootable, incremental back and for one of the images i enable discard for testing purposes.
What am i doing wrong?

Failed to launch VM - Error unable to get volume size
by kushagra.gupta＠hsc.com
Hi,
We're trying to launch the VM with PosixFS Storage and recently we've experienced an error while launching.
We are successfully uploading the image with PosixFS storage in Storage -> Disks.
After upload, we get the status of image upload as illegal, then we are executing the below command on management-engine, and the status changes to OK.
`/usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t all`
Now, When we are creating VM with the same image. Then at the launch time, we got the below errors in /var/log/ovirt-engine/engine.log
`ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-32) [539b710] EVENT_ID: VM_DOWN_ERROR(119), VM OS-22Dec is down with error. Exit message: Unable to get volume size for domain <domain_id> volume <volume_id>`
All storage domains are PosixFS based.
Thanks

Slightly confused by KeyCloak
by theo.pirkl＠hesge.ch
Hi there,
We've decided to use oVirt for our school datacenter and I'm setting up a PoC to show it could work for our needs.
So far, I've managed to deploy a single hosted engine to iSCSI by using the hosted-engine deploy script. So far, so good, I can create VMs, I've had a few problems, but nothing I couldn't figure out.
What got me confused is the KeyCloak link with oVirt. My goal is to allow students to register to oVirt so that they can spin up VMs, images, and so on.
I've created a group in KeyCloak named "ovirt-student" that is automatically assigned to new users.
I have also linked oVirt to this group by going into the engine web UI and adding the group to oVirt's group list.
I have given system permissions to the ovirt-student group such as VMCreator. I've then tried to connect to a dummy user called "test". My results are as follows :
- The user does not seem to have the correct rights as it cannot create new VMs in the VM portal;
- The admin interface does not suggest the user is a part of the ovirt-student group;
However, when I add the test user to the ovirt-administrator group, no problem at all, the user is an admin, alright.
My question is as follows : what do I need to do so that the groups in KeyCloak and oVirt are synced ?
Thanks a lot,
TP

Storage Domain stuck in Maintainance mode
by kushagra.gupta＠hsc.com
Hi Team,
I am new to oVirt.
I have installed version 4.4.10
I am trying to create a new Storage domain of type POSIX compliant FS type.
I have a ceph cluster configure on IPV6.
I was able to create the domain using the following link:
https://www.ovirt.org/documentation/administration_guide/#Understanding_S...
Eventhough the domain was created, it's stuck in maintenance mode.
On checking the engine.log

```
I tried the following link:
https://lists.ovirt.org/pipermail/users/2012-August/009044.html
But this also did not work.
On the other hand on the same ceph node configured NFS server and created a storage domain for that on ovirt and it became active immidiately.
Could anyone please help me out with this?
Thanks and Regards
