2.2. Updating Red Hat Enterprise Virtualization Hypervisors

Procedure 2.2. Updating Red Hat Enterprise Virtualization Hypervisors

1. Log in to the system hosting the Red Hat Enterprise Virtualization Manager as the root user.
2. Ensure that you have the Red Hat Enterprise Virtualization Hypervisor repository enabled:

   # subscription-manager repos --enable=rhel-6-server-rhevh-rpms

   Copy to Clipboard Toggle word wrap
3. Update the rhev-hypervisor package:
   • Red Hat Enterprise Virtualization Hypervisor 6:

     # yum update rhev-hypervisor6

     Copy to Clipboard Toggle word wrap
   • Red Hat Enterprise Virtualization Hypervisor 7:

     # yum update rhev-hypervisor7

     Copy to Clipboard Toggle word wrap
4. From the Administration Portal, click the Hosts tab, and then select the Hypervisor that you intend to upgrade.
   • If the Hypervisor requires updating, an alert message under Action Items and an icon next to the Hypervisor's name indicate that a new version of the Red Hat Enterprise Virtualization Hypervisor is available.
   • If the Hypervisor does not require updating, no alert message or icon is displayed and no further action is required.
5. Click Upgrade to open the Upgrade Host confirmation window.
6. Select the appropriate Hypervisor ISO image.
7. Click OK. The details of the Hypervisor are updated in the Hosts tab, and the status will transition through these stages:

   • Maintenance
   • Installing
   • Non Responsive
   • Up

   These are all expected, and each stage will take some time.
8. Restart the Hypervisor to ensure all updates are correctly applied.
