20.4 Verifying the KVM Installation

It is worthwhile checking that the KVM installation worked correctly before moving forward. When KVM is installed and running, two modules will have been loaded into the kernel. The presence or otherwise of these modules can be verified in a terminal window by running the following command:

# lsmod | grep kvm

Assuming that the installation was successful the above command should generate output similar to the following:

# lsmod | grep kvm

kvm_intel 237568 0

kvm 737280 1 kvm_intel

irqbypass 16384 1 kvm

Note that if the system contains an AMD processor the kvm module will likely read kvm_amd rather than kvm_intel.

The installation process should also have configured the libvirtd daemon to run in the background. Once again using a terminal window, run the following command to ensure libvirtd is running:

# systemctl status libvirtd
