Bhyve's strengths include its minimal overhead, which allows it to achieve near-native performance for virtual machines. It is designed to be efficient and lightweight, leveraging the capabilities of the FreeBSD operating system for performance and network management. </span><br /> +<br /> +<span>Bhyve supports running a variety of guest operating systems, including FreeBSD, Linux, and Windows, on hardware platforms that support hardware virtualization extensions (such as Intel VT-x or AMD-V). In our case, we are going to virtualize Rocky Linux, which later on in this series will be used to run k3s.</span><br /> +<br /> +<h2 style='display: inline' id='basic-bhyve-setup'>Basic Bhyve setup</h2><br /> +<br /> +<span>For the management of the Bhyve VMs, we are using <span class='inlinecode'>vm-bhyve</span>, a tool not part of the FreeBSD operating system but available as a ready-to-use package.
