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