Re: broker.log not rotating
by Strahil Nikolov
Yes, ovirt-ha-broker and ovirt-ha-agent take care of HostedEngine to be up and running and in case something goes bad - to be migrated away.

oVirt 4.4.0, slave interfaces are down after a reboot
by Erez Zarum
Fresh installation of oVirt 4.4.0 (using the ISO), after restarting an host, the host comes up but the slave interfaces of a bond remains in down state.
The only way to bring it up is to login via IPMI and restart the "NetworkManager" service.
Weird thing, after this, the host says that it's network is out of sync, this happens on a network that is marked as "migration network", what is out of sync is the gateway.
I have restart the host again (this happens on all hosts) and i can see that after a restart the NetworkManager state (nmcli c show bond0.421 as example) does not list the routes, after syncing the routes are there.

iSCSI array "Storage domain does not exist" error after array reboot
by Kevin Doyle
I am running a hosted engine using iscsi. I had to reboot the array, I took down all the VM's and put the VM data storage into maintenance mode. I also put the hosted engine "hosted-engine --set-maintenance --mode =global" and shut down the engine "hosted-engine --vm-shutdown" I also stopped the broker and agent systemctl stop ovirt-ha-broker' ; 'systemctl stop ovirt-ha-agent' The array was rebooted. I started the broker and agent systemctl start ovirt-ha-broker' ; 'systemctl start ovirt-ha-agent' However I now see errors in the vdsm log

I have 6 hosts. I have tried rebooting them all, I have tried just running 1 host that was originally hosting the engine, but I cannot bring up the hosted engine. Has anyone any ideas ? how to reconnect the storage domain The hosted engine had its own iscsi disk separate from the VM's

How to use sysprep to create Windows templates
by wodel youchi
Hi,
I need to create some Windows Templates for my client, and I am not quite
familiar with the Windows sysprep installations.
I read the "Sealing a Windows Virtual Machine for Deployment as a Template"
on the Virtual Machine Management Guide.
What I don't understand is the process of sealing a Windows VM.
When should I use the /usr/share/ovirt-engine/conf/sysprep/sysprep.* files?
at the creation of the VM that will be a template at the end? or at the
creation of new VMs based on the template?
When should I use the /etc/ovirt-engine/osinfo.conf.d/xx.files.properties?
at the creation of the VM that will be a template at the end? or at the
creation of new VMs based on the template?
What is the difference between : "Use Cloud-Init/Sysprep" in the VM edit
window and the RUN Once window?
For me it is not clear, could someone help me to understand.
Regards.

Re: Migration of self Hosted Engine from iSCSI to Gluster/NFS
by houwei.chen＠vinchin.com
Hi Erez,
would you like to use the backup tool to backup your self Hosted Engine from iSCSI, then restore to the Gluster of NFS storage? In this way, you can migration as you want.
If you are looking forward to a backup tool, maybe you can try Vinchin Backup & Recovery, which provides the solution.
Hope you can solve your question soon.

Using ovirt imageio
by Łukasz Kołaciński
Dear ovirt community,
I am trying to use ovirt imageio api to receive changed blocks (dirty bitmap) on ovirt 4.4. Could anyone tell me how to get them step by step? On the documentation I saw endpoint "GET /images/ticket-uuid/map". I don't know what ticket-uuid is and how to generate it. I also need to know how to use this api because I can't reach it via /ovirt-engine/api/
I am asking about this endpoint:

Re: Problems with setting up ovirt 4.4 for incremental backups
by Eyal Shenitzky
Hi Lukasz,
Thank you for testing the new Incrementa backup feature.
For those kinds of questions, it is better to send the mail to +users
<users(a)ovirt.org> list so other people can learn/answer the question.
Please see my comments inline.

Currently no, those are the two best resources for this feature at this
moment.
Note that we updated
https://www.ovirt.org/develop/release-management/features/storage/increme...
recently
so now it contains up-to-date information about all the operations that
need to be done with the Engine in order to use this feature.

Please try the following request -
PUT path-to-engine
/ovirt-engine/api/vms/vm-uuid/diskattachments/disk-attachment-uuid
<disk_attachment>
<disk>
<name>disk-uuid</name>
<backup>incremental</backup>
</disk>
</disk_attachment>

There is no 'checkpoints' service under any path at this moment, so the
path you are using is not valid.
There is a backups service that you can find under -
GET path-to-engine/ovirt-engine/api/vms/vm-uuid/backups
To get a single backup you can use
GET path-to-engine/ovirt-engine/api/vms/vm-uuid/backups/backup-uuid
We are now working on exposing also the checkpoints service to allow
removal of checkpoints, but this isn't ready yet.

Please look and the example script we developed in order to use this
feature -
https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/backup...
Using this script you will be able to do all the needed operations in order
to back up a VM.
There is a very detailed manual for it (when using --help / -h).
This script can interact with ImageIO in order to download the backup disks
using the new 'client' library in ImageIO.
You can use it as a reference on how to interact with the Engine API and
ImageIO.

> vdsm 4.40.16-1
>
It looks like you have the correct versions in order to use Incremental
backup, but remember that the
Engine blocks incremental backup operations and allows only full backup by
default.
In order to allow incremental backup in the engine, you need to do the
following commands -
# engine-config -s "IsIncrementalBackupSupported=true"
# systemctl restart ovirt-engine

oVirt-node 4.4.0 - Hosted engine deployment fails when host is unable to download updates
by Marco Fais
Hi,
fresh installation of oVirt-node 4.4.0 on a cluster -- the hosted-engine
--deploy command fails if DNF is unable to download updates.
This cluster is not connected to the public network at the moment.
If I use a proxy (setting the relevant env. variables) it fails at a later
stage (I think the engine VM is trying to download updates as well, but
encounters the same issue and doesn't seem to use the proxy).
With oVirt-node 4.3.x I didn't have this issue -- any suggestions?
[~]# hosted-engine --deploy
[ INFO ] Stage: Initializing
[ INFO ] Stage: Environment setup
During customization use CTRL-D to abort.
Continuing will configure this host for serving as hypervisor and
will create a local VM with a running engine.
The locally running engine will be used to configure a new
storage domain and create a VM there.
At the end the disk of the local VM will be moved to the shared
storage.
Are you sure you want to continue? (Yes, No)[Yes]:

New fenceType in oVirt code for IBM OpenBMC
by Vinícius Ferrão
Hello,
After some days scratching my head I found that oVirt is probably missing fenceTypes for IBM’s implementation of OpenBMC in the Power Management section. The host machine is an OpenPOWER AC922 (ppc64le).
The BMC basically is an “ipmilan” device but the ciphers must be defined as 3 or 17 by default:
[root@h01 ~]# ipmitool -I lanplus -H 10.20.10.2 root -P 0penBmc -L operator -C 3 channel getciphers ipmi
ID IANA Auth Alg Integrity Alg Confidentiality Alg
3 N/A hmac_sha1 hmac_sha1_96 aes_cbc_128
17 N/A hmac_sha256 sha256_128 aes_cbc_128
The default ipmilan connector forces the option cipher=1 which breaks the communication.
So I was reading the code and found this “fenceType” class, but I wasn't able to found where to define those classes. So I can create another one called something like openbmc to set cipher=17 by default.
Another question is how bad the output is, it only returns a JSON-RPC generic error. But I don’t know how to suggest a fix for this.
Thanks,

Re: broker.log not rotating
by Darrell Budic
They’re just log files, so generally safe to delete. You may want to take a look at the huge one though, see what’s up. I had a similar problem that turned out to be a broken HA agent install, cleaned and reinstalled and it went back to the same volume of logs as the others.
Now I need to check if they added logrotate.d config files for it to clean those up, hum.
