% podman-machine-os-apply 1
## NAME
podman\-machine\-os\-apply - Apply an OCI image to a Podman Machine's OS
## SYNOPSIS
**podman machine os apply** [*options*] *image* [vm]
## DESCRIPTION
Apply machine OS changes from an OCI image.
VM's that use OS's that use rpm-ostreee have the capability to rebase itself from the content of an OCI image.
`podman machine image apply` takes an OCI image with container native ostree functionality and rebases itself on that image.
By default, Podman machines on Mac and Linux use an rpm-ostree based distribution (Fedora CoreOS).
For more information, see the [rpm-ostree documentation](https://coreos.github.io/rpm-ostree/container/).
The default machine name is `podman-machine-default`. If a machine name is not specified as an argument,
then the OS changes will be applied to `podman-machine-default`.
## OPTIONS
#### **--help**
Print usage statement.
#### **--restart**
Restart VM after applying changes.
## EXAMPLES
Update the default Podman machine to the specified bootable OCI image.
```
$ podman machine os apply quay.io/podman_next
```
Update the specified Podman machine to the specified bootable OCI image.
```
$ podman machine os apply quay.io/podman_next podman-machine-default
```
