根据平台选择对应的版本，bare-metal(裸金属/裸机)

vmware.x86_64.ova

fedora-coreos-32.20200629.3.0-vmware.x86_64.ova

step2: fcos config

#Configuration process

Ignition configurations are formatted as JSON, which is quick and easy for a machine to read. However, these files are not easy for humans to read or write. The solution is a two-step configuration process that is friendly for both humans and machines:

Produce a YAML-formatted Fedora CoreOS Configuration (FCC) file.

Run the Fedora CoreOS Configuration Transpiler (fcct) to convert the YAML file into a JSON Ignition file.

During the transpilation process, fcct verifies the syntax of the YAML file, which can catch errors before you use it to launch the FCOS system.

Once you have an Ignition (.ign) file, you can use it to boot an FCOS system in a VM or install it on bare metal

docker pull quay.io/coreos/fcct
docker pull quay.mirrors.ustc.edu.cn/coreos/fcct

docker run -i --rm quay.io/coreos/fcct --pretty --strict <fcos.fcc > fcos.ign

cat fcos.ign | base64 -w0

step3: import ova to vmware

文件--->打开--->xxxx.ova
