Upgrading RHEV-M 3.3 to RHEV-M 3.4 Beta

Leave a reply

In order to update RHEV Manager from 3.3 to 3.4 beta we can follow this procedure:

yum-config-manager --enable rhel-6-server-rhevm-3-beta-rpms
yum-config-manager --enable rhel-6-server-beta-rpms
yum-config-manager --enable rhel-6-server-rhevh-beta-rpms
engine-upgrade-check
yum update rhevm-setup -y
engine-setup
yum update rhevm-dwh rhevm-reports -y
engine-setup
yum update rhev-hypervisor6 -y

If upgrading rhevm-reports fails is due to this bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1086003

As a workaround first we need to upgrade jasper reports server and install openjdk dev rpm and re-run engine-setup once more:

yum update jasperreports-server-pro -y
yum install java-1.7.0-openjdk-devel.x86_64 -y
engine-setup

How to upgrade our RHEV-H hypervisors with RHEVM?

Leave a reply

Once we’ve installed RHEVM and our RHEV-H’s how should I upgrade the hypervisors?

In order to do so, on the RHEVM machine, we need to install the isos images of RHEV-H:

yum install rhev-hypervisor6.noarch

NOTICE: If you’re unable to install this package add the following channel:

rhn-channel --add -c rhel-x86_64-server-6-rhevh

And we’ll notice that /usr/share/rhev-hypervisor/ contains the iso images of RHEV-H:

ls /usr/share/rhev-hypervisor/
 rhev-hypervisor.iso
 rhevh-6.2-20120209.0.el6_2.iso
 version-6.2-20120209.0.el6_2.txt
 rhev-hypervisor6.iso
 rhevh-latest-6.iso
 version.txt

Once it’s installed, we can put our RHEV-H into maintenance mode, and will see this option:

  • Host is in maintenance mode, you can Activate it by pressing the Activate button. If you wish to upgrade or reinstall it click here.
And just click “here” and select which RHEV-H iso image are you going to use:
  • rhevh-latest-6.iso

And that would be it, let RHEVM install the upgrade and the node would be automatically rebooted with the newer version of RHEV-H.

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

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

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

Leave a reply

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)?

Leave a reply

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
