NAME

podman-machine-set - Sets a virtual machine setting

SYNOPSIS

podman machine set [options] [name]

DESCRIPTION

Change a machine setting.

Rootless only.

OPTIONS

--cpus=number

Number of CPUs. Only supported for QEMU machines.

--disk-size=number

Size of the disk for the guest VM in GB. Can only be increased. Only supported for QEMU machines.

--help

Print usage statement.

--memory, -m=number

Memory (in MB). Only supported for QEMU machines.

--rootful

Whether this machine should prefer rootful (true) or rootless (false) container execution. This option will also update the current podman remote connection default if it is currently pointing at the specified machine name (or podman-machine-default if no name is specified).

Unlike podman system connection default this option will also make the API socket, if available, forward to the rootful/rootless socket in the VM.

EXAMPLES

To switch the default VM podman-machine-default from rootless to rootful:

$ podman machine set --rootful

or more explicitly:

$ podman machine set --rootful=true

To switch the default VM podman-machine-default from rootful to rootless:

$ podman machine set --rootful=false

To switch the VM myvm from rootless to rootful:

$ podman machine set --rootful myvm
