NAME
virtlockd - libvirt lock management daemon SYNOPSIS
virtlockd [ -dv ] [ -f config_file ] [ -p pid_file ] virtlockd --version DESCRIPTION
The virtlockd program is a server side daemon component of the libvirt virtualization management system that is used to manage locks held against virtual machine resources, such as their disks. This daemon is not used directly by libvirt client applications, rather it is called on their behalf by libvirtd. By maintaining the locks in a standalone daemon, the main libvirtd daemon can be restarted without risk of losing locks. The virtlockd daemon has the ability to re-exec() itself upon receiving SIGUSR1, to allow live upgrades without downtime. The virtlockd daemon listens for requests on a local Unix domain socket. OPTIONS
-h, --help Display command line help usage then exit. -d, --daemon Run as a daemon and write PID file. -f, --config FILE Use this configuration file, overriding the default value. -p, --pid-file FILE Use this name for the PID file, overriding the default value. -v, --verbose Enable output of verbose messages. -V, --version Display version information then exit. SIGNALS
On receipt of SIGUSR1 virtlockd will re-exec() its binary, while maintaining all current locks and clients. This allows for live upgrades of the virtlockd service. FILES
When run as root. SYSCONFDIR/virtlockd.conf The default configuration file used by virtlockd, unless overridden on the command line using the -f|--config option. LOCALSTATEDIR/run/libvirt/virtlockd-sock The sockets libvirtd will use. LOCALSTATEDIR/run/virtlockd.pid The PID file to use, unless overridden by the -p|--pid-file option. When run as non-root. $XDG_CONFIG_HOME/virtlockd.conf The default configuration file used by libvirtd, unless overridden on the command line using the -f|--config option. $XDG_RUNTIME_DIR/libvirt/virtlockd-sock The socket libvirtd will use. $XDG_RUNTIME_DIR/libvirt/virtlockd.pid The PID file to use, unless overridden by the -p|--pid-file option. If $XDG_CONFIG_HOME is not set in your environment, libvirtd will use $HOME/.config If $XDG_RUNTIME_DIR is not set in your environment, libvirtd will use $HOME/.cache EXAMPLES
To retrieve the version of virtlockd: # virtlockd --version virtlockd (libvirt) 1.1.1 # To start virtlockd, instructing it to daemonize and create a PID file: # virtlockd -d # ls -la LOCALSTATEDIR/run/virtlockd.pid -rw-r--r-- 1 root root 6 Jul 9 02:40 LOCALSTATEDIR/run/virtlockd.pid # BUGS

NAME
virt-xml-validate - validate libvirt XML files against a schema SYNOPSIS
virt-xml-validate XML-FILE [SCHEMA-NAME] DESCRIPTION
Validates a libvirt XML for compliance with the published schema. The first compulsory argument is the path to the XML file to be validated. The optional second argument is the name of the schema to validate against. If omitted, the schema name will be inferred from the name of the root element in the XML document. Valid schema names currently include "domain" The schema for the XML format used by guest domains configuration "network" The schema for the XML format used by virtual network configuration "storagepool" The schema for the XML format used by storage pool configuration "storagevol" The schema for the XML format used by storage volume descriptions "nodedev" The schema for the XML format used by node device descriptions "capability" The schema for the XML format used to declare driver capabilities EXIT STATUS
Upon successful validation, an exit status of 0 will be set. Upon failure a non-zero status will be set. AUTHOR
