Daniel P. Berrangé 217b564a77 docs: add warning about virt-qemu-run being experimental

We currently note that the QEMU embedded driver is experimental
in the drvqemu.html file, but we should do the same in the
virt-qemu-run man page.

virt-qemu-run

Run a standalone QEMU guest

Manual section: 1
Manual group: Virtualization Support

SYNOPSIS

virt-qemu-run [OPTIONS...] [GUEST-XML]

DESCRIPTION

This tool provides a way to run a standalone QEMU guest such that it is completely independent of libvirtd. It makes use of the embedded QEMU driver support to run the VM placing files under an isolated directory tree. When the guest is run with this tool it is invisible to libvirtd and thus also invisible to other libvirt tools such as virsh.

The virt-qemu-run program will run the QEMU virtual machine, and then block until the guest OS shuts down, at which point it will exit.

If the virt-qemu-run program is interrupted (eg Ctrl-C) it will immediately terminate the virtual machine without giving the guest OS any opportunity to gracefully shutdown.

NOTE: this tool is currently considered experimental. Its usage and behaviour is still subject to change in future libvirt releases. For further information on its usage consult the QEMU driver documentation.

OPTIONS

GUEST-XML

The full path to the XML file describing the guest virtual machine to be booted.

-h, --help

Display the command line help

-v, --verbose

Display verbose information about startup

-r DIR, --root=DIR

Specify the root directory to use for storing state associated with the virtual machine. The caller is responsible for deleting this directory when it is no longer required.

If this parameter is omitted, then a random temporary directory will be created, and its contents be automaticlaly deleted at VM shutdown.

-s XML-FILE,VALUE-FILE, --secret=XML-FILE,VALUE-FILE

Specify a secret to be loaded into the secret driver. The XML-FILE is a path to the XML description of the secret, whose UUID should match a secret referenced in the guest domain XML. The VALUE-FILE is a path containing the raw value of the secret.

EXIT STATUS

Upon successful shutdown, an exit status of 0 will be set. Upon failure a non-zero status will be set.
