If the server has Intel processors with only VT-x (vmx) support but no VT-d support, the validation tool will report the following warning message that you can ignore: QEMU: Checking for device assignment IOMMU support: WARN (No ACPI DMAR table found, IOMMU either disabled in BIOS or not supported by this hardware platform) It is expected because the validation tool does not check Secure Guest on Intel processors: QEMU: Checking for secure guest support: WARN (Unknown if this platform has Secure Guest support) The validation tool will report the following warning message if the server has Intel processors.

In this post, you use a tool, virt-host-validate, to validates that the server is configured in a suitable way to run libvirt hypervisor drivers: $ sudo apt install -y libvirt-clients $ sudo virt-host-validate You can check if the server supports Virtualization Technology (VT) in various methods. Re-synchronize the package index files from their sources and install the newest versions of all packages currently installed on the system: $ sudo apt update & sudo apt upgrade -y $ sudo apt update This post is a step-by-step tutorial that will help you to create a KVM VM using Ubuntu server 20.04 cloud image with the following network properties: a static MAC address, a pre-defined network interface name, and a static internal IP address. However, it will sometimes require static or fixed values to configure some network properties before setting up a guest VM, especially when it comes to VM provisioning. KVM automatically generates a MAC address and assigns a default network interface name and a dynamic IP address for the guest VM if a user does not provide them when creating the VM.

In most cases, users can perform their tasks against KVM Virtual Machines (VM) without knowing their network configuration, such as the Media Access Control (MAC) addresses and the network interface names.
