29.1.4 Installing Virtualization Packages on an Existing System

Log in as the root user on the target Oracle Linux system.
Ensure that your system has the appropriate Yum repository or ULN channel enabled for the virtualization package versions that you wish to install. See Section 29.1.2, “Virtualization Package Yum Repositories and ULN Channels” for more information.
Run the yum update command to ensure the system is up to date.
Install virtualization packages by doing one of the following:
- Use the yum install command to manually install virtualization packages, for example:
```
# yum install libvirt qemu-kvm
```
- Use the yum groupinstall command to install a virtualization package group, for example:
```
# yum groupinstall "Virtualization Host"
```
