Virtual Machine Viewer 0.0.3 (Default branch)
03-11-2008
Virtual Machine Viewer (virt-viewer) is a lightweight interface for interacting with the graphical display of a virtualized guest OS. It uses GTK-VNC and libvirt to look up the VNC server details associated with the guest. It is intended as a replacement for the traditional vncviewer client, since the latter does not support SSL/TLS encryption of x509 certificate authentication.

virt-viewer - display the graphical console for a virtual machine SYNOPSIS
virt-viewer [OPTIONS] -- DOMAIN-NAME|ID|UUID DESCRIPTION
virt-viewer is a minimal tool for displaying the graphical console of a virtual machine. The console is accessed using the VNC or SPICE protocol. The guest can be referred to based on its name, ID, or UUID. If the guest is not already running, then the viewer can be told to wait until is starts before attempting to connect to the console The viewer can connect to remote hosts to lookup the console information and then also connect to the remote console using the same network transport. OPTIONS
The following options are accepted when running "virt-viewer": -h, --help Display command line help summary -V, --version Display program version number -v, --verbose Display information about the connection -c URI, --connect=URI Specify the hypervisor connection URI -w, --wait Wait for the domain to start up before attempting to connect to the console -r, --reconnect Automatically reconnect to the domain if it shuts down and restarts -z PCT, --zoom=PCT Zoom level of the display window in percentage. Range 10-200. -d, --direct Do not attempt to tunnel the console over SSH, even if the main connection URI used SSH. -a, --attach Use libvirt to directly attach to a local display, instead of making a TCP/UNIX socket connection. This avoids the need to authentication with the remote display, if authentication with libvirt is already allowed. This option does not work with remote displays. -f, --full-screen Start with the window maximised to fullscreen --debug Print debugging information -H HOTKEYS, --hotkeys HOTKEYS Override the default hotkey bindings with HOTKEYS. Where HOTKEYS is <action1>=<key1>[+<key2>][,<action2>=<key3>[+<key4>]]. Key-names are case-insensitive, valid actions are: toggle-fullscreen, release-cursor, smartcard-insert and smartcard-remove. Examples: --hotkeys=toggle-fullscreen=shift+f11,release-cursor=shift+f12 --hotkeys=release-cursor=ctrl+alt Note that hotkeys for which no binding is given are disabled, specifying an empty string disables all hotkeys. -k, --kiosk Start in kiosk mode. In this mode, the application will start in fullscreen with minimal UI. It will prevent the user from quitting or performing any interaction outside of usage of the remote desktop session. Note that it can't offer a complete secure solution by itself. Your kiosk system must have additional configuration and security settings to lock down the OS. In particular, you must configure or disable the window manager, limit the session capabilities, use some restart/watchdog mechanism, disable VT switching etc. --kiosk-quit <never|on-disconnect> By default, when kiosk mode is enabled, virt-viewer will remain open when the connection to the remote server is terminated. By setting kiosk-quit option to "on-disconnect" value, virt-viewer will quit instead. Please note that --reconnect takes precedence over this option, and will attempt to do a reconnection before it quits. EXAMPLES
To connect to the guest called 'demo' running under Xen virt-viewer demo To connect to the guest with ID 7 running under QEMU virt-viewer --connect qemu:///system 7 To wait for the guest with UUID 66ab33c0-6919-a3f7-e659-16c82d248521 to startup and then connect, also reconnecting upon restart of VM virt-viewer --reconnect --wait 66ab33c0-6919-a3f7-e659-16c82d248521 To connect to a remote console using TLS virt-viewer --connect xen://example.org/ demo To connect to a remote host using SSH, lookup the guest config and then make a direct non-tunnelled connection of the console virt-viewer --direct --connect xen+ssh://root@example.org/ demo AUTHOR
