VM Portal on a stand alone server
by gal.villaret＠gmail.com
Hi Folks,
I'm rather new to oVirt and loving it.
running 4.4.1.
I would like to be able to run the VM Portal on a stand-alone server for security concerns.
Can anyone point in the right direction for achieving this?
Thanks,
Gal Villaret

ovirt-node-ng-image-update 4.4.1 to 4.4.1.1
by David M. Hornsby
All,
I applied the recent update 4.4.1 -> 4.4.1.1 to a host in a cluster and it failed. After reboot it was hund at the emergency console. I reinstalled 4.4.1 fresh on the host. Prior to adding it back to the cluster I applied the same update with the same result. Is this just a bad update or is the post install script bad.
Thanks,
David.

I think this is not a critical failure, and is not what failed the restore.

This is part of 'engine-setup' output, which 'hosted-engine' runs inside
the engine VM. If you can access the engine VM, you can try finding more
information in /var/log/ovirt-engine/setup/* there. Otherwise, the
hosted-engine deploy script might have managed to get a copy to
/var/log/ovirt-hosted-engine-setup/engine-logs*. Please check/share these.

Another option is to do the restore manually. To find relevant information,
search the net for "enginevm_before_engine_setup".

mixed hyperconverged?
by Philip Brown
I'm thinking of doing an SSD based hyperconverged setup (for 4.3), but am wondering about certain design issues.
seems like the optimal number is 3 nodes for the glusterfs.
but.. I want 5 host nodes, not 3
and I want the main storage for VMs to be separate iSCSI NAS boxes.
Is it possible to have 3 nodes be the hyperconverged stuff.. but then add in 2 "regular" nodes, that dont store anything and arent part of the cluster?
is it required to be part of the gluster cluster, to also be part of the ovirt cluster, if thats where the hosted-engine lives?
or can I just have the hosted engine be switchable between the 3 nodes, and the other 2 be VM-only hosts?
Any recommendations here?
I dont what 5 way replication going on. Nor do I want to have to pay for large SSDs on all my host nodes.
(Im planning to run them with the ovirt 3.4 node image)

using which client? remote-viewer? on which platform?
qxl needs drivers, not sure if Arch has that…it should have, but for Windows you definitely need to install them. If they’re not all right it falls back to vga emulation which is then slow indeed

What permission do I need to get API access
by miguel.garcia＠toshibagcs.com
We use LDAP authentication to login to ovirt cluster, actually, admin and another user account have to access API with no problem. My account does cannot access to API despite that had SuperUser privileges than those accounts that already access API.
Every time I tried to access API I get next message:
Error during SSO authentication access_denied: Cannot authenticate user 'diagsbuilder(a)ralntdom.rtptgcs.com':
No valid profile found in credentials..
The account does exist and permissions to enter to portal vms
What do need to do to grant access to API?

Re: Problem with backuping ovirt 4.4 with SDK

Lets move the discussion to devel(a)ovirt.org, I think it will be more
productive.
Also, always CC me and Eyal on incremental backup questions for a quicker

This means that starting backup failed. Unfortunately the API does not have
a good way to get
the error that caused the backup to fai.
You should be able to see the error in the event log in the UI, and in
engine log.

So backup from the API was successful?
Backups are expected to disappear, they are temporary objects used to
manage the backup
process. Once the backup process was finished you can do nothing with the
backup object,
and you cannot fetch the same backup data again.
> and I couldn't try incremental.
>
The fact that the backup disappeared should not prevent the next backup.
After you create a backup, you need to poll backup status until the backup
is ready.
while backup.phase != BackupPhase.READY:
time.sleep(1)
backup = backup_service.get()# to_checkpoint_id will be used as
If the backup does not end in ready state, it failed, and you cannot do
anything with
this backup.
When the backup is ready, you can fetch the to_checkpoint_id created for
this backup.
checkpoint_id = backup.to_checkpoint_id
At this point you need to persist the checkpoint id. This will be used to
create the incremental
backup.

This is correct, backup has failed.
Please check the event log to understand the failure.
Eyal, can you show how to get the error from the backup using the SDK, in a
way
that can be used by a program?
e.g. a public error code that can be used to decide on the next step, and
an error
message that can be used for displaying error to users of the backup
application.
This should be added to the backup_vm.py example.
