Reboot the specified XenServer hosts. The specified hosts must be disabled first using the xe host-disable
command, otherwise a HOST_IN_USE error message is displayed.
The host(s) on which this operation should be performed are selected using the standard selection mechanism
(see host selectors above). Optional arguments can be any number of the host parameters listed at the beginning
of this section.
If the specified XenServer hosts are members of a pool, the loss of connectivity on shutdown will be handled and
the pool will recover when the XenServer hosts returns. If you shut down a pool member, other members and
the master will continue to function. If you shut down the master, the pool will be out of action until the master
is rebooted and back on line (at which point the members will reconnect and synchronize with the master) or
until you make one of the members into the master.
host-restore
host-restore [file-name=<backup_filename>] [<host-selector>=<host_selector_value>...]
Restore a backup named file-name of the XenServer host control software. Note that the use of the word
"restore" here does not mean a full restore in the usual sense, it merely means that the compressed backup file
has been uncompressed and unpacked onto the secondary partition. After you've done a xe host-restore, you
have to boot the Install CD and use its Restore from Backup option.
The host(s) on which this operation should be performed are selected using the standard selection mechanism
(see host selectors above). Optional arguments can be any number of the host parameters listed at the beginning
of this section.
host-set-hostname-live
host-set-hostname host-uuid=<uuid_of_host> hostname=<new_hostname>
Change the hostname of the XenServer host specified by host-uuid. This command persistently sets both
the hostname in the control domain database and the actual Linux hostname of the XenServer host. Note that
hostname is not the same as the value of the name_label field.
host-shutdown
host-shutdown [<host-selector>=<host_selector_value>...]
Shut down the specified XenServer hosts. The specified XenServer hosts must be disabled first using the xe host-
disable command, otherwise a HOST_IN_USE error message is displayed.
The host(s) on which this operation should be performed are selected using the standard selection mechanism
(see host selectors above). Optional arguments can be any number of the host parameters listed at the beginning
of this section.
If the specified XenServer hosts are members of a pool, the loss of connectivity on shutdown will be handled and
the pool will recover when the XenServer hosts returns. If you shut down a pool member, other members and
the master will continue to function. If you shut down the master, the pool will be out of action until the master is
rebooted and back on line, at which point the members will reconnect and synchronize with the master, or until
one of the members is made into the master. If HA is enabled for the pool, one of the members will be made
into a master automatically. If HA is disabled, you must manually designate the desired server as master with the
pool-designate-new-master command. See the section called “pool-designate-new-master”.
host-syslog-reconfigure
host-syslog-reconfigure [<host-selector>=<host_selector_value>...]
Reconfigure the syslog daemon on the specified XenServer hosts. This command applies the configuration
information defined in the host logging parameter.
