Red Hat Virtualization (RHV) is an x86 virtualization product produced by Red Hat, based on the KVM hypervisor. Red Hat Virtualization uses the SPICE protocol and VDSM (Virtual Desktop Server Manager) with a RHEL-based centralized management server.In this tutorial, we will perform red hat hypervisor upgrade to 4.3.19
Prerequisites
Ensure that there are no hardware errors on the RHVH hypervisor which you are going to upgrade by verifying the syslog
Verify that /Data-Domain and /OS-domain are independent paritions on the system
Red Hat Hypervisor Upgrade
Perform below steps on the hypervisor from ssh
#cd /etc/pki/product;
#rm -rf product/;
#cp /etc/pki/product-default/328.pem /etc/pki/product
#rm -rf /etc/pki/consumer
#rm -rf /etc/pki/entitlementSetup Proxy
Setup and configure proxy for RHSM if you are behind proxy server
# vi /etc/rhsm/rhsm.conf
proxy_hostname = xx.xx.xx.xx
proxy_port = 3128Clean Subscription manager
# subscription-manager cleanRemove the hypervisor from Red Hat subscriptions from red hat portal
Reregister system with Red Hat
# subscription-manager register
user id: xxxxxxx
password: xxxxxxAttach Subscription
Attach the Red Hat virtualization subscription to the system
# subscription-manager attach --autoConfigure Repositories for hypervisor upgrade
# subscription-manager repos --enable=rhel-7-server-rhvh-4-rpmsShutdown Vm’s
We need to shut down all the running vms on the red hat hypervisor which needs to be updated
Put the host in Maintenance Mode.
In the Administration Portal, click Compute → Hosts and select the host to be updated. Click Management → Maintenance
Updating RHV hypervisor

# yum install redhat-virtualization-host-image-update-4.3.19-20211013.0Reboot the hypervisor
We need to reboot the hypervisor from ssh console or from RHV management console
# rebootOnce the server is reboot, we can verify the Version using below command
# cat /etc/*releaseRemoving maintenance mode
Access the upgraded hypervisor from RHV manager, go to Hosts and click on Activate to remove the hypervisor from maintenance mode
