How to install RHEV Manager (RHEVM) Report?

Did you know that with RHEVM we can generate and create awesome reports?

If not, please, give it a try and install and configure RHEVM reports:

yum install -y rhevm-reports.noarch
rhevm-reports-setup
rhevm-dwh-setup

Once it’s configured you’ll need to access to this URL:

  • https://<FQDN>:8443/rhevm-reports/

Remember that the default administrator user it’s called: rhevm-admin

How to install RHEV Manager (RHEV) Web Admin? (Technology Preview!)

In RHEV 3.0 we’re very near to ditch out our windows clients for administrating RHEVM plataform once and forever.

In order to do so we need to install the new HTML5 webadmin portal (normally it’s installed by default):

yum install -y rhevm-webadmin-portal.x86_64
service jbossas restart

And then you’ll need to access to this URL:

  • https://<FQDN>:8443/webadmin/webadmin/WebAdmin.html

Finally, take into account that:

  • Under Chrome works quite well but remember that there’s no SPICE plugin for Chrome web browser. So if you need to see the console of your guest, Firefox is the way to go.
  • Be aware that is not yet 100% functional as the other Administration Portal because it’s just in technology preview!

How to install RHEV Manager 3.0 (RHEVM)?

In order to install RHEVM we’ll need 2 things:

  • RHEL 6.2 x64
  • RHN account

Afterwards we’ll need to install RHEL 6.2 x64 with @base channel and update it to the minor release available once it is fully installed:

rhn_register
yum upgrade -y

And then we’ll proceed installing the necessary channels for RHEVM:

rhn-channel --add -c rhel-x86_64-server-6-rhevm-3
rhn-channel --add -c jbappplatform-5-x86_64-server-6-rpm
rhn-channel --add -c rhel-x86_64-server-supplementary-6
rhn-channel --add -c rhel-x86_64-server-6-rhevh

And as a last step we’ll only need to install RHEVM and configure it:

yum install -y rhevm
rhevm-setup

Afterwards you’re good to go to the RHEVM Administration Portal:

  • http://<FQDN>:8080/
  • https://<FQDN:8443/RHEVManager

REMEMBER that RHEV Manager only works with clients that can satisfy this requirements:

  • Microsoft Windows (7, XP, 2003 or 2008) with Internet Explorer 7 and above
  • Microsoft .NET Framework 4
If you want to use a Linux client check my future posts 😉

How to connect RHEV 3.0 IPA to Active Directory?

In a default installation we have two methods of authentication:

But, how about connecting our IPA to an Active Directory? Piece of cake! We just need to add it through the command line:
rhevm-manage-domains -action=list
rhevm-manage-domains -action=add -domain='your.nice.domain' -user='your.ad.admin.user.' -interactive
service jbossas restart
After that we can check that our Active Directory is correctly up and running, trying to connect it through:
rhevm-manage-domains -action=list
rhevm-manage-domains -action=validate
If it validates, all should be fine! Just try to log in with your admin IPA user and set up some users/perms from your AD, and then just authenticate with your user/pass of the AD.
If it doesn’t work just take into account:
  1. Remember to restart jbossas service after setting up your AD domain!
  2. On the UserPortal/RHEVManager remember to select the correct domain from the combobox!
  3. If you can add your AD domain, did you try to add it with another administration user of your AD?
And just in case you just broke IPA and don’t remember your internal admin password ([email protected]), you can change it through:
rhevm-config -s AdminPassword=<newpassword>
service jbossas restart

Deep dives RHEV3 GA

Per la gent que no es vulgui registrar us adjunto els pdf’s del deep dives que es varen publicar:

És molt interessant el roadmap per la versió del 3.1 on apareixeran noves funcionalitats que encara manquen la solució de RHEV comparant-la amb la de VMware vSphere.

RHEV 3.0 GA

Finalment, després d’esperar uns quants mesos ja ha sortit la versió de RHEV3 GA!

Com a novetats podeu mirar tant la documentació oficial com els vídeos i presentacions de l’event que es va realitzar aquest passat dia 18 de Gener:

I com a cirereta ens ofereixen una versió de 60 dies amb suport per tal de provar la nova versió:
Així que ja podeu preparar els vostres POC i qui sap, algún dia, desfer-nos dels nostres estimats ESXi’s.
