Maybe obvious but have you set the firewall on Win10 to allow pings ( it 
defaults to blocking them).

Hello Domikin
I have already set No Networkfilter on all involved vNIC profiles. 
Unfortunately the BRIGDE cannot ping Win10. It can only ping router.

Hi Strahil,

Thank you.
One maybe stupid question, but significant to me:
Considering i haven’t been playing before with hyperconverged setup in oVirt, 
is this something i can do from ui cockpit or does it require me first setup an 
Glusterfs on the Hosts before doing anything via oVirt API or Web interface?

Kindly awaiting your reply.

[ovirt-users] Re: Clean up engine database?

2019-10-11 Thread Pavel Šipoš 

Hi!

We have similar problem and it looks like psql vacuuming isn't working 
properly.
I expect that this problem will be gone when we will upgrade ovirt to 
latest version.
Until then we are performing weekly vacuuming of top N (usualy 4) tables 
by "external size" in ovirt_engine_history database.


A little bit more about vacuuming: 
https://www.postgresql.org/docs/9.1/sql-vacuum.html
External size: 
https://wiki-bsse.ethz.ch/display/ITDOC/Check+size+of+tables+and+objects+in+PostgreSQL+database 
, https://matjaz.it/tutorial-sizes-of-tables-and-databases-in-postgresql/


Example which queries we are running in our case:

To get top 4 tables ordered by "external size":
SELECT relname, pg_size_pretty(pg_total_relation_size(relid)), 
pg_size_pretty(pg_total_relation_size(relid) - pg_relation_size(relid)) 
FROM pg_catalog.pg_statio_user_tables ORDER BY 
pg_total_relation_size(relid) DESC limit 4;


We use names from previous query and perform vacuum table by table:
VACUUM (VERBOSE, FULL) ${TABLE};

To get new size of table after vaccuming:
SELECT pg_size_pretty(pg_total_relation_size(relid) - 
pg_relation_size(relid)) FROM pg_catalog.pg_statio_user_tables WHERE 
relname::text like '${TABLE}';


Note that ${TABLE} is variable with value for example: 
"vm_interface_samples_history"


I suggest to run few queries and check "external size" of your tables.

In our case vacuuming has huge effect on releasing disk space and it 
takes jus few seconds for database.


Oh yes, I almost forgot. As Strahi said, there is some ovirt tool 
(script) for cleaning up psql database but in our case it didn't have 
such huge effect as it didn't perform full vacuum.


Regards,
Pavel

Chapter 7: Backing up and Restoring an EL-Based Self-Hosted Environment. The

Subject: [ovirt-users] Move Hosted Engine to external oVirt or VMware

Hi,

I've got a oVirt Infrastructure with 4 nodes and a self-hosted engine. The 
hosted engine also manages additional 4 nodes in 4 datacenters.

Two tasks:
- Re installation of our infrastructure without interfering or interrupting the 
external nodes.
- Separate the external hosts from our infrastructure by either leaving them in 
the old hosted engine or setting up a new hosted engine on VMware or the new 
Ovirt Infrastructure

We've already drained 2 of our 4 nodes, re-installed them with ovirt node and a 
new self-hosted engine and moved our VMs onto it.
On the two remaining nodes only runs the old self-hosted engine which still 
manages the 4 external hosts - which prevents me from reinstalling that 
remaining hosts. I'd prefer to move the old HE to the new oVirt Installation or 
to our VMware infrastructure. Is that possible and what pitfalls do I have to 
care of?

Many thanks for any hint on this!
Markus

ok, so the problem seems to be that the external network connecting
BRIGDE to Win10 is not working.

Can you please share the current ovn-controller.log of the hosts running
BRIGDE and Win10?
Were both hosts installed into a cluster with ovirt-provider-ovn as
default network provider?

Does reconfiguration of ovn like described in
https://www.ovirt.org/documentation/admin-guide/chap-External_Providers.html#configuring-hosts-for-an-ovn-tunnel-network
fixes the issue?
If not, can you please share the ovn-controller.log after the
reconfiguration?

If "No Networkfilter" is set on all involved vNIC Profiles, oVirt will
not block any traffic. Is "No Networkfilter" set already on all

Is BRIDGE able to ping both other VMs?

[ovirt-users] FOSDEM 2020 Virtualization & IaaS Devroom CfP

2019-10-11 Thread Piotr Kliczewski 
We are excited to announce that the

call for proposals is now open for the Virtualization & IaaS devroom at the

upcoming FOSDEM 2020, to be hosted on February 1st 2020.

This year will mark FOSDEM’s 20th anniversary as one of the longest-running

free and open source software developer events, attracting thousands of

developers and users from all over the world. FOSDEM will be held once

again in Brussels, Belgium, on February 1st & 2nd, 2020.

This devroom is a collaborative effort, and is organized by dedicated folks

from projects such as OpenStack, Xen Project, oVirt, QEMU, KVM, and

Foreman. We would like to invite all those who are involved in these fields

to submit your proposals by December 1st, 2019.

About the Devroom

The Virtualization & IaaS devroom will feature session topics such as open

source hypervisors and virtual machine managers such as Xen Project, KVM,

bhyve, and VirtualBox, and Infrastructure-as-a-Service projects such as
KubeVirt,

Apache CloudStack, OpenStack, oVirt, QEMU and OpenNebula.

This devroom will host presentations that focus on topics of shared

interest, such as KVM; libvirt; shared storage; virtualized networking;

cloud security; clustering and high availability; interfacing with multiple

hypervisors; hyperconverged deployments; and scaling across hundreds or

thousands of servers.

Presentations in this devroom will be aimed at developers working on these

platforms who are looking to collaborate and improve shared infrastructure

or solve common problems. We seek topics that encourage dialog between

projects and continued work post-FOSDEM.

Important Dates

Submission deadline: 1 December 2019

Acceptance notifications: 10 December 2019

Final schedule announcement: 15th December 2019

Devroom: 1st February 2020

Submit Your Proposal

All submissions must be made via the Pentabarf event planning site[1]. If

you have not used Pentabarf before, you will need to create an account. If

you submitted proposals for FOSDEM in previous years, you can use your

existing account.

After creating the account, select Create Event to start the submission

process. Make sure to select Virtualization and IaaS devroom from the Track

list. Please fill out all the required fields, and provide a meaningful

abstract and description of your proposed session.

Submission Guidelines

We expect more proposals than we can possibly accept, so it is vitally

important that you submit your proposal on or before the deadline. Late

submissions are unlikely to be considered.

All presentation slots are 30 minutes, with 20 minutes planned for

presentations, and 10 minutes for Q

All presentations will be recorded and made available under Creative

Commons licenses. In the Submission notes field, please indicate that you

agree that your presentation will be licensed under the CC-By-SA-4.0 or

CC-By-4.0 license and that you agree to have your presentation recorded.

For example:

"If my presentation is accepted for FOSDEM, I hereby agree to license all

recordings, slides, and other associated materials under the Creative

Commons Attribution Share-Alike 4.0 International License. Sincerely,

."

In the Submission notes field, please also confirm that if your talk is

accepted, you will be able to attend FOSDEM and deliver your presentation.

We will not consider proposals from prospective speakers who are unsure

whether they will be able to secure funds for travel and lodging to attend

FOSDEM. (Sadly, we are not able to offer travel funding for prospective

speakers.)

Submission Guidelines

Mentored presentations will have 25-minute slots, where 20 minutes will

include the presentation and 5 minutes will be reserved for questions.

The number of newcomer session slots is limited, so we will probably not be

able to accept all applications.

You must submit your talk and abstract to apply for the mentoring program,

our mentors are volunteering their time and will happily provide feedback

but won't write your presentation for you!

If you are experiencing problems with Pentabarf, the proposal submission

interface, or have other questions, you can email our devroom mailing

list[2] and we will try to help you.

How to Apply

In addition to agreeing to video recording and confirming that you can

attend FOSDEM in case your session is accepted, please write "speaker

mentoring program application" in the "Submission notes" field, and list

any prior speaking experience or other relevant information for your

application.

Code of Conduct

Following the release of the updated code of conduct for FOSDEM, we'd like

to remind all speakers and attendees that all of the presentations and

 Good.

 Some other things:
   - what's the output of 'ip a' on ovirt-engine ?
   - ssh into one of the hosts in that cluster and do 'ovs-vsctl list
 Open'

 With this we can check that the OVN configuration is correct.

"VM network" is modeled as usage in the sdk, so an empty attribute
"usages" does the trick:


system_service = connection.system_service()
networks_service = system_service.networks_service()
networks_service.add(

Yes, it's that one.

AFAIK it's not going to fail the whole deployment because we added an
ignore over that kind of errors.
AFAIK it's not systematic.

[ovirt-users] Bridge Issue

2019-10-11 Thread Constantinos L 
Hello all,
I am trying to setup a bridge. I have 3 virtual machines. The 1st acting as 
router, the second acting as bridge and the 3rd is the client, like the 
following diagram
   ROUTER   
  BRIDGECLIENT
internet(ovirtmng network) - [eth0  router --eth1 ] ---[eth0 --[br0]-- 
eth1] ---[--eth Windows 10]

The problem is that windows 10 is not able to connect the internet although is 
able to allocate ip. I use ovirt external network to connect the VMs to each 
other.
It seems that Windows 10 sends ARP to BRIDGE, the BRIDGE sends the ARP to 
ROUTER but the replies are not passing the br0 when it comes a reply from 
ROUTER to Windows 10.
I use oVirt 4.3.6. Do you know what should be the issue ? Is there a chance 
that ovirt blocking the bridge?

This setting would be at host side, where things are ok to put a timeout of
X seconds using entries such as

devices {
device {
all_devsyes
# Set timeout of queuing of 5*28 = 140 seconds
# similar to vSphere APD timeout

no_path_retry   28

ACTION=="add", SUBSYSTEMS=="scsi", ATTRS{vendor}=="QEMU*",
ATTRS{model}=="QEMU HARDDISK*", ENV{DEVTYPE}=="disk", RUN+="/bin/sh -c
'echo 180 > /sys$DEVPATH/device/timeout'"

so that guest disk timeout is more than host storage.
Any other settings?

2019-10-11 Thread adrianquintero 
I think I finally found the issue, it it was related to 
tasks/add_hosts_storage_domains.yml where hosts: localhost should be set to 
hosts: host1.example.other.com

As mentioned all worked except for one warning:

TASK [ovirt.hosted_engine_setup : Always revoke the SSO token] 
***
fatal: [host1.example.other.com]: FAILED! => {"changed": false, "msg": "You 
must specify either 'url' or 'hostname'."}
...ignoring

host1.example.other.com : ok=418  changed=150  unreachable=0failed=0
skipped=220  rescued=0ignored=1   

I researched a bit about this error and found 
https://github.com/ansible/ansible/issues/53379 but not sure if this is still 
the case.

any feedback is welcome.

thank you,

Adrian
