Installing KVM Virtualization Packages on existing RHEL 6 System
To install virt packages on RHEL 6 you can register your host machine to RHN Satellite and entitle you host to virtualization entitlement or you can create a local yum repository using your RHEL 6 DVD or downloaded iso and run the below commands .
#yum install kvm
Finally install additional virtualization management packages
#yum install virt-manager libvirt libvirt-python python-virtinst libvirt-client
Once you installed the kvm packages check the kvm modules are properly loaded using
# lsmod |grep kvm
kvm_intel 45674 0
kvm 291811 1 kvm_intel
So you are ready to spindle up the new virtual machines . But before that Configure Network Ethernet Bridge Interface to use with virtual machines to talk to the external world .
Note: Steps are same for RHEL5 as well as RHEL6 but KVM is available on RHEL5 Update 4 and later releases of RHEL.
