Thanks for the feedback Juan.
I confirm that using fence_rhevm from latest CentOS 7 version it worked.
These were the lines in my cluster.conf
























Using admin@internal didn't work even if I set the permissions at vm
level too...

It worked with my username (g.cecchi) that has SuperUser system
privilege and also at VM level.

Is it yet necessary to have a user with SuperUser privilege at system level?

Tomorrow (today... ;-) I'm going to open a bugzilla to backport the feature.

Thanks again,
Gianluca

Hi Niyazi,

Thanks for sharing with the community! There is definitely a need for this.

Just curious -- do you have plans to allow direct exporting of a VM snapshot? 
That would eliminate one copy operation.

Best,
Daniel

[ovirt-users] engine upgrade 3.5 -> 4.1.1

[Sverker Abrahamsson]

Hi
I upgraded an old ovirt installation from 3.5 to latest version, but end 
up with this error message when running engine-setup:


[ INFO  ] Stage: Setup validation
[ ERROR ] It seems that you are running your engine inside of the 
hosted-engine VM and are not in "Global Maintenance" mode. In that case 
you should put the system into the "Global Maintenance" mode before 
running engine-setup, or the hosted-engine HA agent might kill the 
machine, which might corrupt your data.
[ ERROR ] Failed to execute stage 'Setup validation': Hosted Engine 
setup detected, but Global Maintenance is not set.


This is not a hosted engine, so why does it think so? How can I get it 
past this step?

That is a known issue:

  fence_rhevm can only work as RHEV admin user not a regular user (that
requires "Filter: true http header)
  https://bugzilla.redhat.com/1287059

That was fixed in fence-agents-4.0.11-47.el7, but I guess it wasn't
backported to CentOS 6.

I'd suggest that you open a bug for this component in the Red Hat
Enterprise Linux bug tracker, requesting that the fix be back-ported.

Meanwhile, if you are in a hurry, you can take the CentOS 7 fence_rhev
script, which should work.

You will most likely also need to add --ssl-indecure to the command line
of the agent, because you will most likely be using the default self
signed certificate authority used by the engine.

Note that the latest version of this script uses the 'Filter: true'
header to drop privileges. That means that even when using
'admin@internal' you have to make sure that 'admin@internal' has
permissions for the VM that you want to fence, otherwise it will not be
able to find/fence it.

[ovirt-users] Info on fence_rhevm against oVirt 4.1.1

[Gianluca Cecchi]

Hello,
I'm trying to use fence_rhevm in a CentOS 6.8 guest that is part of a
virtual rhcs cluster

My sw version for fence_agents inside guest is
fence-agents-4.0.15-12.el6.x86_64 and I notice that for this particular
agent nothing changes also using the latest available package
fence-agents-4.0.15-13.el6.x86_64.rpm apart

[root@p2vnorasvi1 ~]# diff fence_rhevm /usr/sbin/fence_rhevm
13c13
< BUILD_DATE="(built Wed Mar 22 04:24:11 UTC 2017)"
---
> BUILD_DATE="(built Tue May 10 22:28:47 UTC 2016)"
[root@p2vnorasvi1 ~]#

The VM name in oVirt 4.1.1 is p2vorasvi1

Running this command against the engine I get

[root@p2vnorasvi1 network-scripts]# fence_rhevm -a 10.4.192.43 -l
"admin@internal" -p "mypassword" -z --shell-timeout=20 --power-wait=10 -v
-o status -n p2vorasvi1
vms/?search=name%3Dp2vorasvi1



404 Not Found

Not Found
The requested URL /api/vms/ was not found on this server.



Failed: Unable to obtain correct plug status or plug is not available

Actually I get the same error even if I put a wrong password

What am I missing...?
Do I have to specify DC/cluster if I have more than one, or other
parameters?

Thanks,
Gianluca

[ovirt-users] change Memory Ballooning setting

[Nelson Lameiras]

Hello oVirt gurus, 

When activating/deactivating memory balloning on VM, this will change 
/usr/libexec/qemu-kvm command line on host on vm startup (you can see it using 
"ps aux"). 
So I understand a vm reboot is needed to take this change into account. 

But when activating/deactivating memory balloning on Cluster (plus MoM Sync on 
host) I do not really understand what happens "under the hood" 

- Is there a mechanism on host which controls "memory balloning" globally? 
- Is it able to change it's behaviour "on the fly" with "MoM Sync" ? 

If you have any information, it would be greatly appreciated

Of course, once the VM is installed, I can go in and change the RAM to
512 MB and it´ll boot just fine. It´s as you say that it´s just the
installer that absolutely needs it.

That is also an option but I just don´t want to have a dozen images to

Ok, thanks for the report, I opened a specific bug to track it:
https://bugzilla.redhat.com/1446094

In the mean time you could just
edit /etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf removing the
line:
  OVESETUP_CONFIG/imageioProxyConfig=bool:False
and execute engine-setup again.

You can consider using the CentOS cloud image. It is available from
the oVirt image repository and AFAIR can boot in VMs with as little as
500MB of RAM.

I think its just the installer that needs that much RAM, if you boot
from pre-installed images you can do with much less (And you can also
save on disk space and I/O by using thin clones).

Ok, I'll try that one.

I think that you are looking for vdsHeartbeatInSeconds which specifies 
acceptable time of no activity.
You can increase it which would make it more resilient to network fluctuations.

Please note that it is part of the host life cycle and too big value would 
limit our ability to detect real network issues.

Thanks,
Piotr

FWIW, I created a NIC- and Disk-less Template with the settings I
wanted and pointed to that template in my "Small" Foreman "Compute
profile", so that I could create a VM in oVirt from Foreman with 512 MB
RAM.

/K

PS. CentOS 7 won´t even pxe-boot with any less than 1536 MB any way :(

BTW: if I try to set the video type to Cirrus from web admin gui (and
automatically the Graphics Protocol becomes "VNC"), I get this when I press
the OK button:

Error while executing action:

HostedEngine:

   - There was an attempt to change Hosted Engine VM values that are locked.

Did the engine imported it automatically once you had your first regular

 On 4.1.1, the 96% of the cpu time of ovirt-ha-agent is still spent in
 connect() in /usr/lib/python2.7/site-packages/vdsm/jsonrpcvdscli.py
 and the 95.98% is in Schema.__init__ in /usr/lib/python2.7/site-pac
 kages/vdsm/api/vdsmapi.py

 So it's still the parsing of the api yaml schema.
 On master we already merged a patch to reuse an existing connection if
 available and this should mitigate/resolve the issue:
 https://gerrit.ovirt.org/73757/

 It's still not that clear why we are facing this kind of performance
 regression.

Yes, it should work although we never officially back-ported and tested it
for 4.1.z.

Re: [ovirt-users] Timeout for Hosts

[Oved Ourfali]

Hi Sven,

Relevant configuration items are:
vdsTimeout (which is set by default to 180 seconds, so you should be good)
vdsHeartbeatInSeconds (this one should be increased)

iirc no other changes are needed, but CC-ing Martin just in case i'm wrong.

Best regards,
Oved

[ovirt-users] Timeout for Hosts

[Sven Achtelik]

Hi All,

I have 2 hosts which are at remote locations where the ISP is forcing a 
connection reset after some days. During that reset the connection will be down 
for at most 2 minutes and the engine starts to complain about the hosts not 
being reachable. What is the right value to tweak to compensate this ?
Is it on of these: TimeoutToResetVdsInSeconds, VdsRefreshRate, vdsTimeout ? And 
is it possible to only apply this for a certain cluster or DC or is it global ?

Thank you,

Sven
