Virtualization Options
Virtualization options let you run Flatcar as a VM on a hypervisor you manage, rather than delegating the VM lifecycle to a
cloud provider
. You are responsible for booting the image, attaching storage and networking, and delivering the Ignition config to the guest (for example via QEMU fw_cfg, a config-drive, or the hypervisor’s guest-info channel).
Some hypervisors are officially covered by the Flatcar test suite (QEMU, libvirt); others are maintained by community contributors and marked (community support) in the sidebar.
