Limitation in using Ovirt SSO Token
by Hari Prasanth Loganathan
Hi Team,
I would like to know, Is there any limitation in using the same sso token
for multiple request.
I observe that when I use the same sso token for more than 900 HTTP Rest
request, the application went down. Is there any limitation in using same
SSO token? I could see that my status is showing as ACTIVE and memory and
CPU seem fine. Still, the oVirt is not reachable and I need to restart it
to access again.

ovirt 4.2 gluster configuration
by Edoardo Mazza
Hi all,
Scenario:
3 nodes each with 3 interfaces: 1 for management, 1 for gluster, 1 for VMs
Management interface has it own name and its own ip (es. name = ov1, ip=
192.168.1.1/24), the same is for gluster interface which has its own name
and its own ip (es. name = gluster1, ip= 192.168.2.1/24).
When configuring bricks from Ovirt Management tools I get the error: "no
uuid for the name ov1".
Network for gluster communication has been defined on network/interface
gluster1.
What's wrong with this configuration?
Thanks in advance.

Pre-snapshot scripts to run before live snapshot
by Gianluca Cecchi
Hello,
this thread last year (started by me... ;-) was very useful in different
aspects involved
http://lists.ovirt.org/pipermail/users/2017-March/080322.html
We did cover memory save or not and fsfreeze automatically done by guest
agent if installed inside the VM.
What about pre-snapshot scripts/operations to run inside guest, to have
application consistency?
Eg if I have a database inside the VM and I have scripted my backup job
involving live-snapshot (eg with the backup.py utility of the thread)
Can I leverage this kind of functionality with the oVirt guest agent?
Or is it mandatory to consider a remote connection to the VM (via ssh or
what for windows?) and execute the script/command/bat file?
What are you curently doing in this respect?
Thanks,
Gianluca

Tunable parameters in ovirt engine
by Hari Prasanth Loganathan
Hi Team,
*Description of problem:*
I am trying to achieve 1000 concurrent request to oVirt. What are the
tunable parameters to achieve this?
I tried to perform the benchmarking for ovirt engine using Apache benchmark
using the same SSO token.
ab -n 1000 -c 500 -k -H "accept: application/json" -H "Authorization:
Bearer SSOTOKEN" https://172.30.56.70/ovirt-engine/
<https://172.30.56.70/ovirt-engine/api/vms/5440271b-afb3-48bb-9ff1-076fc07...>
When the number of concurrent request is 500, we are getting more than 100
failures with the following error,
SSL read failed (1) - closing connection
139620982339352:error:
NOTE: It is scaling for concurrent request below 500.
I used the profiler to get the memory and CPU and it seems very less,
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+
COMMAND
30413 ovirt 20 0 4226664 882396 6776 S 126.0 23.0 27:48.53 java
Configuration of the machine in which Ovirt is deployed :
RAM - 4GB,
Hard disk - 100GB,
core processor - 2,
OS - Cent7.x.
In which 2GB is allocated to oVirt.
Version-Release number of selected component (if applicable):
4.2.2
How reproducible:
If the number of concurrent requests are above 500, we are easily facing
this issue.
*Actual results:*
SSL read failed (1) - closing connection
139620982339352:error:
*Expected results:*
Request success.
Thanks,
Hari

Fibre Channel Protocol (FCP)
by maoz zadok
Hello All,
I connected existing data center with NFS storage domain to a new
Fiber-Channel storage domain according to the following guide, and I have
three questions.
https://www.ovirt.org/documentation/install-guide/chap-Configuring_Storage/
1. why does the storage domain asks me to "Use Host"?
- does it mean that if this host is down there is no access to the FC
storage or the next available host elected to manage the FC storage?
- does it mean that all the traffic to my storage is routed via the
selected host?
- what is the best practice, do I need to split the workload to other
hosts as well by letting each host manage one small LUN instead of letting
one host manage all LUNs or one big LUN?
2. is it possible to set the newly created fiber-channel storage(data
domain) as master?
3. can I easily migrate all VM disks to the FC storage instead of the NFS?
Thank you!

Unable to start VM after upgrade vom 4.1.9 to 4.2.1 - NPE
by Jan Siml
Hello,
we have upgrade one of our oVirt engines to 4.2.1 (from 4.1.9) and
afterwards all nodes too. The cluster compatibility level has been set
to 4.2.
Now we can't start a VM after it has been powered off. The only hint we
found in engine.log is:

New oVirt blog - Your Container Volumes Served By oVirt
by Yaniv Kaul
When running a virtualization workload on oVirt, a VM disk is 'natively' a
disk somewhere on your network-storage.
Entering containers world, on Kubernetes(k8s) or OpenShift, there are many
options specifically because the workload can be totally stateless, i.e
they are stored on a host supplied disk and can be removed when the
container is terminated. The more interesting case is *stateful workloads* i.e
apps that persist data (think DBs, web servers/services, etc).
k8s/OpenShift designed an API to dynamically provision the container
storage (volume in k8s terminology).
In this post I want to cover how oVirt can provide volumes for containers
running on k8s/OpenShift cluster.
