9.3. Installing the CloudPlatform Agent on a KVM Host
Each KVM host must have the CloudPlatform Agent installed on it. This Agent communicates with the
Management Server and controls all the instances on the host. Install the CloudPlatform Agent on
each host using the following steps.
1. Check for a fully qualified hostname.
# hostname --fqdn
This should return a fully qualified hostname such as "kvm1.lab.example.org". If it does not, edit /
etc/hosts so that it does.
2. Remove qemu-kvm. CloudPlatform provides a patched version.
# yum erase qemu-kvm
3. If you do not have a Red Hat Network account, you need to prepare a local Yum repository.
a. If you are working with a physical host, insert the RHEL installation CD. If you are using a VM,
attach the RHEL ISO.
b. Mount the CDROM to /media.
