HA and poweroff of VM
by Gianluca Cecchi
Hello,
after setting a VM as HA I run poweroff from inside the VM.
Is it supposed to be automatically restarted in this scenario with oVirt
4.1?
In engine I see:
VM c7service is down. Exit message: User shut down from within the guest
Apparently no restart
How to test eventually HA functionality?
Tanks,

I have a host which was updated since 3.6....
libcacard is disappeared from ovirt4.1 but it has a many dependencies which

questions on OVN
by Gianluca Cecchi
Hello,
I'm successfully testing and using OVN on a single host environment with
self hosted engine and 4.1
I'm using ip of ovirtmgmt for the host local ip used for OVN tunneling,
even if actually with a single host it is not so important...
ovirtmgmt bridge is on top ot lacp based bonding
Now I would like to apply it on another environment composed by 3 hosts.
Here ovirtmgmt bridge is on top of an active-backup bonding.
Are there any cons to put the local ip used for tunneling on ovirtmgmt ip?
Any problems/impacts on engine access/functionality using this ip for the
tunnel?
Is in genera OVN considered stable/fully usable in 4.1?
Thanks in advance,
Gianluca

iscsi or iser targets are not detached from the host in the maintenance mode
by Arman Khalatyan
Hi,
In ovirt 4.1 when I put the host into maintenance mode then the nfs mounts
are unmounted as expected.
but the hosts are still logged into the targets.
Is it expected behavior?? If yes what is the use of it?
Another thing concerning to the permanently removed direct LUNs.
They are still in the /var/lib/iscsi/nodes and /var/lib/iscsi/send_targets/*
Would be good to cleanup the folders if users are removing permanently the
LUNs.
Thanks,
Arman.

vdsm conf files sync
by Gianluca Cecchi
Hello,
in my 2 original 4.1 hosts I got some storage errors using rdbms machines
when restoring or doing hevy I/O.
My storage domain is FC SAN based.
I solved the problem setting this conservative settings into
/etc/vdsm/vdsm.conf.d
cat 50_thin_block_extension_rules.conf
[irs]
# Together with volume_utilization_chunk_mb, set the minimal free
# space before a thin provisioned block volume is extended. Use lower
# values to extend earlier.
volume_utilization_percent = 25
# Size of extension chunk in megabytes, and together with
# volume_utilization_percent, set the free space limit. Use higher
# values to extend in bigger chunks.
volume_utilization_chunk_mb = 4096
Then I added a third host in a second time and I wrongly supposed that an
equal vdsm configurtion would have been deployed with "New Host" from
gui....
But is not so.
Yesterday with a VM running on this third hypervisor I got the previous
experimented messages; some cycles of these
VM dbatest6 has recovered from paused back to up.
VM dbatest6 has been paused due to no Storage space error.
VM dbatest6 has been paused.
in a 2 hours period.
Two questions:
- why not align hypervisor configuration when adding host and in particular
the vdsm one? Any reason in general for having different config in hosts of
the same cluster?
- the host that was running the VM was not the SPM.
Who is in charge of applying the settings about volume extension when a VM
I/O load requires it because of a thin provisioned disk in use?
I presume not the SPM but the host that has in charge the VM, based on what
I saw yesterday...
Thanks,
Gianluca

Requirements to use ovirt-image-repository
by Gianluca Cecchi
Hello,
is it sufficient to open outside glance port (9292) of glance.ovirt.org or
is there anything else to do?
Making a test from an environment without outside restrictions it seems
that is only the engine that connects, correct?
Thanks,

Disaster Recovery Testing
by Gary Lloyd
Hi
We currently use direct lun for our virtual machines and I would like to
move away from doing this and move onto storage domains.
At the moment we are using an ISCSI SAN and we use on replicas created on
the SAN for disaster recovery.
As a test I thought I would replicate an existing storage domain's volume
(via the SAN) and try to mount again as a separate storage domain (This is
with ovirt 4.06 (cluster mode 3.6))
I can log into the iscsi disk but then nothing gets listed under Storage
Name / Storage ID (VG Name)
Should this be possible or will it not work due the the uids being
identical ?
Many Thanks
*Gary Lloyd*

Exporting VM as ova
by Benjamin Alfery
Hi,
I'm using ovirt 4.0 and was wondering if it is possible to export an
existing VM to ova format (via the gui). If it's not possible via GUI,
is that possible at all?
Best Regards
