NAME

virt-qemu-qmp-proxy - Expose a QMP proxy server for a libvirt QEMU guest

SYNOPSIS

virt-qemu-qmp-proxy [/OPTION/]… DOMAIN QMP-SOCKET-PATH

DESCRIPTION

This tool provides a way to expose a QMP proxy server that communicates with a QEMU guest managed by libvirt. This enables standard QMP client tools to interact with libvirt managed guests.

NOTE: use of this tool will result in the running QEMU guest being marked as tainted. It is strongly recommended that this tool only be used to send commands which query information about the running guest. If this tool is used to make changes to the state of the guest, this may have negative interactions with the QEMU driver, resulting in an inability to manage the guest operation thereafter, and in the worst case potentially lead to data loss or corruption.

The virt-qemu-qmp-proxy program will listen on a UNIX socket for incoming client connections, and run the QMP protocol over the connection. Any commands received will be sent to the running libvirt guest, and replies sent back.

The virt-qemu-qmp-proxy program may be interrupted (eg Ctrl-C) when it is no longer required. The libvirt QEMU guest will continue running.

OPTIONS

DOMAIN

The ID or UUID or Name of the libvirt QEMU guest.

QMP-SOCKET-PATH

The filesystem path at which to run the QMP server, listening for incoming connections.

-c CONNECTION-URI *–connect*=/CONNECTION-URI/

The URI for the connection to the libvirt QEMU driver. If omitted, a URI will be auto-detected.

-v, –verbose

Run in verbose mode, printing all QMP commands and replies that are handled.

-h, –help

Display the command line help.

EXIT STATUS

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