Re: [ovirt-users] Using VDSM to edit management interface

[Kirin van der Veer]

Ďakujem Peter, but this doesn't seem to work in my case.
/etc/resolv.conf is regenerated by Network Manager after a reboot and my
domain settings are lost.
Your comments regarding the reliance on DNS make sense for most
installations, but in my case oVirt is a secondary service that I would not
expect to run unless our core infrastructure is working correctly.
I'm hesitant to edit /etc/hosts directly, since that can lead to confusion
when the underlying IP addresses change.
For now I will hardcode the IPs of my servers.
It's frustrating (and surprising) that there is not an easy way to do this.

Kirin.

[ovirt-users] Setting up a LDAP conf

[Jose Fernandes]

Hello,


I have an OpenDJ LDAP server, and I need some help to do query on a specific 
filter search.


We can't figure out how to create a "aaa/profile1.properties" file with these 
configs.


This is how we can filter the users with ldapsearch on our ldap server:


-H ldaps://server:port -D uid=user,ou=OU,dc=SERVER,dc=com,dc=br -W -b 
ou=aa,dc=bb,dc=cc,dc=dd uid=jose.fernandes


 - My configuration does not permit I search the users on base, so I need to do 
this filter on "ou=aa,dc=bb,dc=cc,dc=dd"

 - Port is different from common.


Someone can help me to create the config file?

José Fernandes

Re: [ovirt-users] ovirt 4.2.2-rc3 switching from legacy to OVS..

[Thomas Davis]

Alrighty, I figured it out.

0) To setup a node in a cluster, make sure the cluster is in OVS, not 
legacy.


1) Make sure you have an OVN controller setup somewhere.  Default 
appears to be the ovirt-hosted-engine.
   a) you should also have the external network provider for OVN 
configured also; see the web interface.


2) when you install the node, make sure it has openvswitch installed and 
running - ie:
   a) 'systemctl status openvswitch' says it's up and running. (be sure 
it's enable also)

   b) 'ovs-vsctl show' has vdsm bridges listed, and possibly a br-int
  bridge.

3) if there is no br-int bridge, do 'vdsm-tool ovn-config 
ovn-controller-ip host-ip'


4) when you have configured several nodes in the OVN, you should see 
them listed as geneve devices in 'ovs-vsctl show', ie:


This is a 4 node cluster, so the other 3 nodes are expected:

[root@d8-r12-c1-n3 ~]# ovs-vsctl show

ovs_version: "2.7.3"

5) Create in the cluster the legacy style bridge networks - ie, 
ovirtmgmt, etc.  Do this just like you where creating them for the 
legacy network.  Define the VLAN #, the MTU, etc.


6) Now, create in the network config, the OVN networks - ie, 
ovn-ovirtmgmt is on an external provider (select OVN), and make sure 
'connect to physical network' is checked, and the correct network from 
step 5 is picked.  Save this off.


This will connect the two networks together in a bridge, and all 
services are visible to both ie dhcp, dns..


7) when you create the VM, select the OVN network interface, not the 
legacy bridge interface (this is why I decided to prefix with 'ovn-').


8) Create the vm, start it, migrate, stop, re-start, etc, it all should 
work now.


Lots of reading.. lots of interesting stuff found..  finally figured 
this out after reading a bunch of bug fixes for the latest RC (released 
today)

[ovirt-users] Host can not boot any more with current kernel

[Jonathan Baecker]

Hello everybody,

Today I update my engine, from 4.2.1.6 to 4.2.1.7 and later I update two 
hosts. All are running on CentOS 7.4


Now they have the kernel 3.10.0-693.21, one host I can start normal and 
the other one always reboot short after the menu where I can select the 
kernel. There is not even an error message and I can not switch to the 
boot log screen.


The same behavior I have with kernel 3.10.0-693.17. Kernel *.11 and 
older are working.


Have any body experience this issue and know what to do?

[ovirt-users] gluster self-heal takes cluster offline

[Jim Kusznir]

Hi all:

I'm trying to understand why/how (and most importantly, how to fix) an
substantial issue I had last night.  This happened one other time, but I
didn't know/understand all the parts associated with it until last night.

I have a 3 node hyperconverged (self-hosted engine, Gluster on each node)
cluster.  Gluster is Replica 2 + arbitrar.  Current network configuration
is 2x GigE on load balance ("LAG Group" on switch), plus one GigE from each
server on a separate vlan, intended for Gluster (but not used).  Server
hardware is Dell R610's, each server as an SSD in it.  Server 1 and 2 have
the full replica, server 3 is the arbitrar.

I put server 2 into maintence so I can work on the hardware, including turn
it off and such.  In the course of the work, I found that I needed to
reconfigure the SSD's partitioning somewhat, and it resulted in wiping the
data partition (storing VM images).  I figure, its no big deal, gluster
will rebuild that in short order.  I did take care of the extended attr
settings and the like, and when I booted it up, gluster came up as expected
and began rebuilding the disk.

The problem is that suddenly my entire cluster got very sluggish.  The
entine was marking nodes and VMs failed and unfaling them throughout the
system, fairly randomly.  It didn't matter what node the engine or VM was
on.  At one point, it power cycled server 1 for "non-responsive" (even
though everything was running on it, and the gluster rebuild was working on
it).  As a result of this, about 6 VMs were killed and my entire gluster
system went down hard (suspending all remaining VMs and the engine), as
there were no remaining full copies of the data.  After several minutes
(these are Dell servers, after all...), server 1 came back up, and gluster
resumed the rebuild, and came online on the cluster.  I had to manually
(virtsh command) unpause the engine, and then struggle through trying to
get critical VMs back up.  Everything was super slow, and load averages on
the servers were often seen in excess of 80 (these are 8 core / 16 thread
boxes).  Actual CPU usage (reported by top) was rarely above 40% (inclusive
of all CPUs) for any one server. Glusterfs was often seen using 180%-350%
of a CPU on server 1 and 2.

I ended up putting the cluster in global HA maintence mode and disabling
power fencing on the nodes until the process finished.  It appeared on at
least two occasions a functional node was marked bad and had the fencing
not been disabled, a node would have rebooted, just further exacerbating
the problem.

Its clear that the gluster rebuild overloaded things and caused the
problem.  I don't know why the load was so high (even IOWait was low), but
load averages were definately tied to the glusterfs cpu utilization %.   At
no point did I have any problems pinging any machine (host or VM) unless
the engine decided it was dead and killed it.

Why did my system bite it so hard with the rebuild?  I baby'ed it along
until the rebuild was complete, after which it returned to normal operation.

As of this event, all networking (host/engine management, gluster, and VM
network) were on the same vlan.  I'd love to move things off, but so far
any attempt to do so breaks my cluster.  How can I move my management
interfaces to a separate VLAN/IP Space?  I also want to move Gluster to its
own private space, but it seems if I change anything in the peers file, the
entire gluster cluster goes down.  The dedicated gluster network is listed
as a secondary hostname for all peers already.

Will the above network reconfigurations be enough?  I got the impression
that the issue may not have been purely network based, but possibly server
IO overload.  Is this likely / right?

I appreciate input.  I don't think gluster's recovery is supposed to do as
much damage as it did the last two or three times any healing was required.

Thanks!
--Jim

Right.
This issue has been introduced with https://gerrit.ovirt.org/#/c/86435/
that comes in ovirt-hosted-engine-ha-2.2.5 so 4.2.1 is not affected since
it ships ovirt-hosted-engine-ha-2.2.4.

[ovirt-users] UI plugin API updates

[Vojtech Szocs]

Dear community,

the UI plugin API will be updated to reflect recent oVirt web
administration UI design changes.

The relevant patch is already merged in master branch [1] and the
associated BZ [2] is targeted for 4.3 release.

*What's new*

Two new API functions, addPrimaryMenuContainer and addSecondaryMenuPlace,
allow you to add custom secondary menu items to the vertical navigation
menu. You can target both existing (core) and custom primary menu items
when adding secondary ones.

*What's changed*

Some API functions were renamed to stay consistent with current UI design,
i.e. reflecting the absence of "main" and "sub" tabs.

   - addMainTab => addPrimaryMenuPlace
   - addSubTab => addDetailPlace
   - setTabContentUrl => setPlaceContentUrl
   - setTabAccessible => setPlaceAccessible
   - addMainTabActionButton => addMenuPlaceActionButton
   - addSubTabActionButton => addDetailPlaceActionButton

You can still use the original functions mentioned above, but doing so will
yield a warning in the browser console, for example:

*addMainTab is deprecated, please use addPrimaryMenuPlace instead.*


In addition, for functions that used to deal with "main" or "sub" tabs, the
options object no longer supports alignRight (boolean) parameter. That's
because PatternFly tabs widget [3] expects all tabs to be aligned next to
each other, flowing from left to right.

We'll be updating the UI plugins feature page shortly to reflect all the
changes.

[ovirt-users] Warning: CentOS Upgrade with Host Engine - 503 Service Temporarily Unavailable

[Andrei Verovski]

Hi !

I have upgraded CentOS 7.4 with oVirt 4.2.1 host engine (with yum upgrade), and 
its resulted in broken system - "503 Service Temporarily Unavailable" when 
connecting to the host engine via web.
Service ovirt-engine failed to starts (logs attached at the bottom of this 
email), other ovirt services seem to run fine.

yum update "ovirt-*-setup*” (upgrade 4.2 -> 4.2.1)
engine-setup
yum upgrade (OS upgrade)

Is this issue somehow related to JDK as described here?
https://bugzilla.redhat.com/show_bug.cgi?id=1217023

New packages:
java-1.8.0-openjdk  x86_64   1:1.8.0.161-0.b14.el7_4
java-1.8.0-openjdk-develx86_64   1:1.8.0.161-0.b14.el7_4 
java-1.8.0-openjdk-headless x86_64   1:1.8.0.161-0.b14.el7_4 

installed packages (seem to be also 1.8x):
[root@node00 ~]# rpm -qa | grep jdk
java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64
java-1.8.0-openjdk-devel-1.8.0.151-5.b12.el7_4.x86_64
java-1.8.0-openjdk-headless-1.8.0.151-5.b12.el7_4.x86_64
copy-jdk-configs-2.2-5.el7_4.noarch

Since my host engine is actually a KVM appliance under another SuSE server, I 
simply discarded it and reverted back old qcow2 image.

So this is a warning to anyone - don’t upgrade CentOS, or at least keep a copy 
of disk image before ANY upgrade !

Hi Sergey,
I recently had a need for a Windows 2008 R2 x86_64 VM that I moved from
vSphere to RHV (but the considerations below are the same for oVirt).
In my case I had to run a backup of an Oracle database that is in
NOARCHIVELOG mode, due to performance reasons: it is an RDBMS used for BI
that is refreshed every day and doesn't need a point in time recovery but
only a consistent state before the "new day" processing is run at 01:00 in
the night.
In vSphere the backup of the VM was implemented with Veeam, that uses
snaphsot technology and interacts with VSS layer of M$ operating systems.
Oracle fully supports on Windows the backup of database using VSS only if
it is in ARCHIVELOG mode.
https://docs.oracle.com/cd/E11882_01/win.112/e10845/vss.htm#NTQRF475

Veeam automatically executed shutdown / snapshot / start of the dabatase
because I think it implements what in the link above is called as
PRE_SQLCMD in OnPrepareBackup callback (through the VeeamGuestHelper.exe
executable).

Coming back to oVirt, the interaction with Windows VSS layer is indeed done
by "QEMU guest agent"too; you have to install it together with the oVirt
Guest Agent when you install oVirt Guest Tools

So in my case I would need for Windows something similar to the
"fsfreeze/thaw hooks" I have in Linux QEMU guest agent.
But searching through the code it seems this functionality is only present
in Linux component...
In fact some days ago I wrote to the qemu-devel mailing list to ask for
possible implementation:
http://lists.nongnu.org/archive/html/qemu-devel/2018-03/msg02823.html

No answer so far. Feel free (you and others) to contribute to the thread if
you think it can help...
It could also be useful to have at least writer control commands
implementation in VSS interaction of QEMU Guest Agent in Windows, so that
one could do something similar to what Veeam on vSphere already does...

Based on what I have wrote above, I doubt you could interact at all through
the QEMU guest agent on Windows to run any command...
And also for Linux guests, I think you are restricted to the default
actions (eg shutdown) or forced to use as a workaround the approach to run
a snapshot (that then you delete) and "attach" the desired command to the
freeze (or thaw) hook...

HIH,
Gianluca

[ovirt-users] how to run command in windows guest via agent?

[Sergey Vavilov]

Hello!

I'm wondering 
how can I run a cmd.exe command (or powershell) inside windows guest virtual 
machine by
ovirt-agent from outside (from ovirt-engine or from host)?
What's ovirt's analogue for 
virsh qemu-agent-command
?
Actually, I want to setup ip on virtual NIC.
So I can't run a command via windows' protocols.
ovirt-agent service works in windows virtual machine and successfully reports 
its state to ovirt engine.
But it looks like ovirt-agent isn't suitable to run commands in virtual 
machines?
Or am I wrong?
Should I configure a coexistence of ovirt-agent and qemu-agent inside vm 
somehow?
How did you solve such task before?
 
Thank you, all!

Re: [ovirt-users] ovirt 4.2.2-rc3 switching from legacy to OVS..

Make sure STP is OFF for each bridge. Then the warnings go away.

I know OVS is Experimental, but it worked in 4.1.x, and now we have to do a

which vdsm does not do, so suddenly you get the kernel complaining about
seeing it's mac address several times.)

Could you elaborate on this issue? What is wrong with a bridge that
learns its mac from its underlying device? What wold like Vdsm to do,
in your opinion? You can file a bug (or even send a patch) if there is
a functionality that you'd like to fix.

Interesting, as that name is not long enough to trigger the name length

scenario on the latest master branch, and it worked as expected, it created 
the template from the snapshot without issues with that exact same name.

I don't see any recent changes to the frontend code for that dialog either. If 
you look in the engine.log does it say anything? I can only assume some 
validation is failing, and that validation message is not properly propagated 
to the frontend, but it should show something in the backend log regardless.

If you are limited to a single VLAN, I would use this as a single
logical network in oVirt. To isolate the traffic between VMs, I
would use external logical networks on the ovirt-provider-ovn.

Thanks for that quick answer !
   Yes indeed I had some connectivity troubles on this server, a strange

it is working ok, I have no similar errors after the ones you saw.   What can I

This should fix 4.2.1 release notes page:

This should fix similar cases for future release notes pages:

You are welcome to reopen that bug, specifying your use case for OvS.
I cannot promise fixing this bug, as our resources are limited, and
that bug, which was introduced in 4.2, was not deemed as urgently
needed. https://gerrit.ovirt.org/#/c/86932/ attempts to fix the bug,
but it still needs a lot of work.

Could you elaborate on this issue? What is wrong with a bridge that
learns its mac from its underlying device? What wold like Vdsm to do,
in your opinion? You can file a bug (or even send a patch) if there is
a functionality that you'd like to fix.

I hope that

Thank you for sending the logs.

According to the logs, it seems that you had some connectivity issue while
you tried to preview the snapshot.
The preview operation rolled back but according to you failed to finish.

It seems like you still have a connectivity issue with that host (

You can edit the storage domain setting after the storage domain

Hi,

Can you please specify the version of the engine and supply the engine.log
and the vdsm.log?

Moreover, can you please specify the steps that you did that led you to
this issue?

Thanks,

Re: [ovirt-users] NFS 4.1 support and migration

[spfma . tech]

In fact I don't really know how to change storage domains setttings (like nfs 
version or export path, ...), if it is only possible. 

I thought they could be disabled after stopping all related VMS, and maybe 
settings panel would then unlock ? 

But this should be impossible with hosted engine dedicated storage domain as it 
is required for the GUI itself. 

So I am stuck.

[ovirt-users] Ovirt and OVH vRack

[Fabien Carré]

Hello,
I am trying to set up an oVirt environment using OVH servers. So far I have
installed an engine (4.2) and a node. The node is attached to a NAS through
a vRack https://www.ovh.co.uk/solutions/vrack/network-technology.xml. I am
using one vlan to connect it, which is the management network


However it is not a perfect setup (cf attached screenshot). The management
network is in  "Out-of-Sync" state.
on the node :
# ip addr
28: eno4.100@eno4:  mtu 1500 qdisc noqueue
master ovirtmgmt state UP qlen 1000
link/ether 0c:c4:ff:7a:6c:13 brd ff:ff:ff:ff:ff:ff
29: ovirtmgmt:  mtu 1500 qdisc noqueue
state UP qlen 1000
link/ether 0c:c4:ff:7a:6c:13 brd ff:ff:ff:ff:ff:ff
inet 10.100.0.11/24 brd 10.100.0.255 scope global ovirtmgmt
   valid_lft forever preferred_lft forever


[image: Screenshot from 2018-03-15 09-03-37.png]
It does not seem possible to add extra vlan. I wanted to have one for the
vms and one for the hosts.
Can you give me some help or guidance ?

Also generally speaking do you think such a setup is fine ?

Thank you
Fabien

[ovirt-users] [4.2.2-1.el7.centos] Image locked and unending task

[spfma . tech]

Hi,
   I tried to rollback to a snapshot on a VM, but the preview never ended.   
The task has been running for about 15 hours, with this state :   {
 "916b67fb-8808-43d2-850c-1c12650ccc49": {
 "verb": "createVolume", 
 "code": 0, 
 "state": "finished", 
 "tag": "spm", 
 "result": {
 "uuid": "d37ca118-820f-46a3-b99b-714018ea8b42"
 }, 
 "message": "1 jobs completed successfully", 
 "id": "916b67fb-8808-43d2-850c-1c12650ccc49"
 }
}
   I just canceled it : the task list is now empty on the CLI but no change on 
GUI.   So I restared the engine VM, but no success.   With 
"/usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh" I was able to manually 
unlock the image, but the task is still "finalizing".   Is this a bug ?

The last three 4.2.2 release candidates that I've tried have been starting

Please note that the start of this section says:

"For databases managed by engine-setup this is performed
automatically, but non-managed databases (usually remote databases)
this needs to be done manually by administrators."

Is your database remote or managed manually, or local and managed by
engine-setup? If latter, it's enough to run 'engine-setup'.

Sorry, this is a bug in the documentation. The commands should be:

   su - postgres -c "scl enable rh-postgresql95 -- psql -d engine"
   postgres=# DROP FUNCTION IF EXISTS uuid_generate_v1();
   postgres=# CREATE EXTENSION "uuid-ossp";

Indeed.

The reason that this bug happened is that the release notes are (partially)
auto-generated, where this part is taken from the doc-text of the linked bug:

https://bugzilla.redhat.com/show_bug.cgi?id=1515635

The text there is ok.

We should somehow make the resultant markdown mark such doc text as
pre-formatted,
to prevent it from replacing '--' with '–'. Adding Sandro for this.

Thanks for the report!

Sounds to me like you are in the "this will happen automatically" case.

Re: [ovirt-users] Using VDSM to edit management interface

[Peter Hudec]

Hi Kirin,

I suggest to do it old way and edit the /etc/resolv.conf manually.

And one advice. Do not relay on the DNS on infrastructure servers. Use
/etc/hosts. If he DNS will not be accessible, you will have problem to
put it infrastructure up/working. As side effect the hosts allow you
to use short names to access servers.

If you are ansible positive, you could use

hudecof.resolv  https://galaxy.ansible.com/hudecof/resolv/
hudecof.hosts   https://galaxy.ansible.com/hudecof/hosts/
