FENCE_AGENT(8) System Manager's Manual FENCE_AGENT(8) NAME fence_virsh - Fence agent for virsh DESCRIPTION fence_virsh is an I/O Fencing agent which can be used with the virtual machines managed by libvirt. It logs via ssh to a dom0 and there run virsh command, which does all work. By default, virsh needs root account to do properly work. So you must allow ssh login in your sshd_config. fence_virsh accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_virsh can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.

Does not affect --verbose or --debug- file or logging to syslog. -v, --verbose Verbose mode. Multiple -v flags can be stacked on the command line (e.g., -vvv) to increase verbosity. --verbose-level Level of debugging detail in output. Defaults to the number of --verbose flags specified on the command line, or to 1 if ver- bose=1 in a stonith device configuration (i.e., on stdin). -D, --debug-file=[debugfile] Write debug information to given file -V, --version Display version information and exit -h, --help Display help and exit --plug-separator=[char] Separator for plug parameter when specifying more than 1 plug (Default Value: ,) -C, --separator=[char] Separator for CSV created by 'list' operation (Default Value: ,) --delay=[seconds] Wait X seconds before fencing is started (Default Value: 0) --disable-timeout=[true/false] Disable timeout (true/false) (default: true when run from Pace- maker 2.0+) --login-timeout=[seconds] Wait X seconds for cmd prompt after login (Default Value: 5) --missing-as-off Missing port returns OFF instead of failure --power-timeout=[seconds] Test X seconds for status change after ON/OFF (Default Value: 20) --power-wait=[seconds] Wait X seconds after issuing ON/OFF (Default Value: 0) --shell-timeout=[seconds] Wait X seconds for cmd prompt after issuing command (Default Value: 3) --stonith-status-sleep=[seconds] Sleep X seconds between status calls during a STONITH action (Default Value: 1) --retry-on=[attempts] Count of attempts to retry power on (Default Value: 1) --use-sudo Use sudo (without password) when calling 3rd party software --ssh-path=[path] Path to ssh binary (Default Value: /usr/bin/ssh) --sudo-path=[path] Path to sudo binary (Default Value: /usr/bin/sudo) ACTIONS on Power on machine. off Power off machine. reboot Reboot machine. status This returns the status of the plug/virtual machine. list List available plugs with aliases/virtual machines if there is support for more then one device. Returns N/A otherwise. list-status List available plugs with aliases/virtual machines and their power state if it can be obtained without additional commands. monitor Check the health of fence device metadata Display the XML metadata describing this resource. manpage The operational behavior of this is not known. validate-all Validate if all required parameters are entered.
