[ovirt-users] oVirt Active Directory Integration

[Anantha Raghava]

Hi,

I am trying to integrate the oVirt Engine with Active Directory to 
enable user logins. I installed the ovirt ldap extension and executed 
the setup. The process completed successfully and the profile is visible 
in engine log in page.


Now, when I try to add the user and assign the roles, it is not allowing 
me to browse through the profile & the user list. Infact the "GO" button 
gets deactivated as shown in the screenshot.


How do I set this right and get the user list?

Thanks & Regards,

[ovirt-users] ovirt-engine-extension-aaa-ldap-setup > [ ERROR ] Invalid CA certificate: unknown error (_ssl.c:2988)

[aleksey . maksimov]

Hello oVirt guru's!

I want to configure MS Active Directory authentication for oVirt web UI.

I configured an External LDAP Provider in accordance with the instructions:

Link #1) 
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/html/Administration_Guide/sect-Configuring_an_External_LDAP_Provider.html

Link #2) 
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/html/Administration_Guide/Setting_Up_SSL_or_TLS_Connections_between_the_Manager_and_an_LDAP_Server.html

For support LDAP over TLS I did file with all Root certificates 
(~/AD-LDAP-Files/myrootca_chain.pem).

Check file:

$ openssl verify -CAfile ~/AD-LDAP-Files/myrootca_chain.pem 
~/AD-LDAP-Files/ldapserver.pem
/root/AD-LDAP-Files/end.pem: OK

Then I create  JKS (Java Key Store) file (as described in Link #2):

# keytool -importcert -noprompt -trustcacerts -alias myrootcachain -file 
~/AD-LDAP-Files/myrootca_chain.pem -keystore /etc/ovirt-engine/aaa/myrootca.jks 
-storepass changeit
Certificate was added to keystore

Then I run ovirt-engine-extension-aaa-ldap-setup:

# ovirt-engine-extension-aaa-ldap-setup

kvmclock is the most accurate clock in Linux guests. Once you hit a bug we can 
take a look at something, but until then I do not see a reason to modify

[ovirt-users] oVirt 4.0.x - hosted-engine was not starting properly

[Gervais de Montbrun]

Hey All,

Since updating to 4.0.x of oVirt, I have had an issue with my hosted engine. 
After a some poking around, I think I have figured out my issue and thought I 
would share to see what others think.
The issue has existed with 4.0, 4.0.1, 4.0.2, 4.0.3, and still exists in 4.0.4.

Description:
When my hosted engine starts it reports that it is in a degraded state with 7 
or 8 services still not started when I run systemctl status. It takes about 6 
or 7 minutes to eventually start all the services and come online. If I don't 
set my cluster to Global-Maintenance mode it eventually thinks that my 
hosted-engine needs to be rebooted and restarts it before it can start 
everything.

Solution:
I realized that Apache was the culprit and found that the proxy to the 
ovirt-engine in /etc/httpd/conf.d/z-ovirt-engine-proxy.conf has a super long 
timeout with many retries. I changed the settings and now everything works for 
me.

-> Before change:

ProxyPassMatch ajp://127.0.0.1:8702 timeout=3600 retry=5


AddOutputFilterByType DEFLATE text/javascript text/css text/html 
text/xml text/json application/xml application/json application/x-yaml



-> After change:

ProxyPassMatch ajp://127.0.0.1:8702 timeout=5 retry=2


AddOutputFilterByType DEFLATE text/javascript text/css text/html 
text/xml text/json application/xml application/json application/x-yaml



If I read the timeout settings correctly, it will wait 60 minutes with 5 
retries. 5 hours is way too long for my little server to hold onto all those 
apache processes. The change I made allows for there to be an error, and also 
releases apache's hold on the process. Once everything is ready, apache is 
ready to serve requests and everything/everyone is happy. Before making the 
change, I just get a whitescreen in my browser and then nothing works until I 
restart Apache (or I end up in an endless loop of ovirt-ha services restarting 
my hosted-engine.

I noticed that this setting reverts to the original setting, so oVirt must be 
writing this file. Perhaps these number can be changed in oVirt? If not, I will 
just setup and ansible play to revert the settings with working values and 
restart apache on my engine.
:-)

Cheers,
Gervais

Sorry, not really. You said you set up ntpd/chrony correctly. So how can the 
time get out of sync? Why do you think it can be because of kvmclock anyway? Do 
you refer to some specific bug?

Michal, please, read my first message.
I have 3 times wrote that the NTP client works for me.
The question is not that.
The question is how to disable kvm-clock for a virtual machine? Do I have to do 
it at all? If you want, how to do it correctly?

I don't think you can

Aleksey,
I don't understand what issue you have.  Time is getting desynchronized? How 
did you configure your ntp client? Does it behave the same on different 
hypervisor? What is the hypervisor OS?

Re: [ovirt-users] Time synchronization in guest OS for Hosted Engine VM (for Kerberos)

[aleksey . maksimov]

I think that the NTP-client (chrony) in guest OS may conflict with the 
kvm-clock (vm guest OS time sync from vm-host). 
Do I need to turn off  kvm-clock in virtual machine properties? 
And how to do it?

What is not clear in my question?

Re: [ovirt-users] 4-node oVirt with replica-3 gluster

[Goorkate, B.J.]

Hi Sahina,

First: sorry for my delayed response. I wasn't able to respond earlier.

I already planned on adding the 4th node as a gluster client, so thank you for
confirming that this works.

Why I was in doubt is that certain VMs with a lot of storage I/O on the 4th 
node have to
replicate to 3 other hosts (the replica-3 gluster nodes) over the storage 
network, while
a VM on 1 of the replica-3 gluster nodes only has to replicate to two other 
nodes over
the network, thus creating less network traffic. 

Does this make sense?

And if it does: can that be an issue? 

Regards,

Bertjan

ohh, sorry, I was thinking that you were with oVirt 4.0.2 and you want to
run engine-setup without being asked to upgrade to 4.0.4.

oVirt is composed by multiple packages and 4.0.4 and 4.0.2 are in same repo
so it's not enough to simply query for ovirt-engine-4.0.2.6 since you are
going to get anything else from 4.0.4 because 4.0.4 > 4.0.2.
Probably the cleanest option is to use versionlock which also supports
wildcards on packet selection.
But can I ask again why you explicitly need 4.0.2 instead of 4.0.4 since
4.0.4 is just supposed to fix issues? what is bothering you with 4.0.4?
maybe it's a regression.

Re: [ovirt-users] VM incremental backup

[Sven Achtelik]

No, I never came across this approach. I didn’t know about virt-sparsify.

I’ll look into that and give it a try.

Thank you

As I see it you have two options:
- In backup use 'dd' with 'conv=sparse' (or similar tool that allows sparse).
- After backup use virt-sparsify [1] to reduce the size to the real used size 
prior to restore.

To make this extra efficient you can use virt-sparsify anyways after backup to 
make the file even smaller.
Have you considered this approach?

Full VM disk backup. If you use dd you can drop the 0 parts of the disk.

I would like to understand the existence of the possibility of incremental VM

And if it is, the means by which it is achieved.
While I was only able to achieve a complete backup of the virtual machine (but 
it is a very large amount of information and time) by cloning a snapshot of the 
VM and export to data domain.

Re: [ovirt-users] Fencing setting. Power off only

[Martin Perina]

Hi,

the goal for fencing flow is to make host available automatically by doing
power management restart as last resort step. There is no option to do
power management stop instead of restart. The only way how to alert
administrators about fencing is to configure ovirt-engine-notifier,
subscribe administrators to relevant host events and pass those event to
them either by SMTP or SNMP (both can be configured in
ovirt-engine-notifier).

Ciao Matteo,
unfortunately moving an existing hosted-engine env from one storage kind to
another (without manually touching the engine DB) is currently not
supported. Please see:
http://lists.ovirt.org/pipermail/users/2016-July/041526.html

We are going to cover this in 4.1.

We do not have support for this from the KVM level yet. There is upstream
work on this and we hope to be able to do this in the next year.

[ovirt-users] Migrating self hosted engine from iSCSI to NFS ?

[Matteo]

Hi all,

I've a 2 hosts setup with ovirt 4, with a bunch of machines on it.

I started with an old iSCSI unit, then added a new NFS storage server
and started moving all VMs.

All VMs have been migrated over NFS (live storage migration works great!), but
now I need to move also the hosted engine, in order to dismiss the iSCSI 
storage.

So, what're the best guidelines to migrate ?
I suspect that simply doing live storage migration will not work :)

All backups of the hosted engine are available.

Thanks!
Matteo

Re: [ovirt-users] ISO Import

[Johann van der Westhuizen]

Hi,

 

I'm currently on "oVirt Engine Version: 3.3.0-4.el6", will I be able to update 
to the latest version without any issues?

 

I've tried to add a ISO as you told me but wasn't able to, will try again and 
revert back.

Via (storage->new domain) and I have to add "use host" & "export path" - not 
sure what that is?

 

Also, do I need to install the "engine-iso-uploader" on the server where oVirt 
is installed / hosted?

[ovirt-users] blog - real time oVirt host

[Martin Polednik]

Hello oVirt users!

For the past week-or-so, I've been playing with real time hosts in
oVirt. I'm thrilled to say that it works*!

* Now the important bits. There is a lot of configuration that has to
be done manually and some caveats such as no graphics console or
virtio if you want to respect real time boundaries. Additionally, the
steps to enable RT are not uniform and depend on hardware and
application.

That being said, I've still tried to summarize the process of
configuring a real time host in a blog post:

https://mpolednik.github.io/2016/09/19/real-time-host-in-ovirt/

Criticism or your results are welcome!

Re: [ovirt-users] Scheduling policy for oVirt cluster "vm_evenly_distributed"

[Artyom Lukianov]

Please provide all policy parameters(HighVmCount, SpmVmGrace and
MigrationThreshold) also please specify what host is SPM.
You can find some additional information how this policy works here:
