Migrate the specified VMs between physical hosts. The
host
parameter can be either the name or the
UUID of the XenServer host.
By default, the VM will be suspended, migrated, and resumed on the other host. The
live
parameter
activates XenMotion and keeps the VM running while performing the migration, thus minimizing VM
downtime to less than a second. In some circumstances such as extremely memory-heavy workloads in
the VM, XenMotion automatically falls back into the default mode and suspends the VM for a brief period
of time before completing the memory transfer.
The VM or VMs on which this operation should be performed are selected using the standard selection
mechanism (see
VM selectors
). Optional arguments can be any number of the
VM parameters
listed at the
beginning of this section.
vm-reboot
vm-reboot
[
<vm-selector>
=
<vm_selector_value>
...] [force=
<true>
]
Reboot the specified VMs.
The VM or VMs on which this operation should be performed are selected using the standard selection
mechanism (see
VM selectors
). Optional arguments can be any number of the
VM parameters
listed at the
beginning of this section.
Use the
force
argument to cause an ungraceful shutdown, akin to pulling the plug on a physical server.
vm-reset-powerstate
vm-reset-powerstate
[
<vm-selector>
=
<vm_selector_value>
...] {force=true}
The VM or VMs on which this operation should be performed are selected using the standard selection
mechanism (see
VM selectors
). Optional arguments can be any number of the
VM parameters
listed at the
beginning of this section.
This is an advanced command only to be used when a member host in a pool goes down. You can use this
command to force the pool master to reset the power-state of the VMs to be
halted
. Essentially this forces
the lock on the VM and its disks so it can be subsequently started on another pool host. This call requires
the force flag to be specified, and fails if it is not on the command-line.
vm-resume
vm-resume
[
<vm-selector>
=
<vm_selector_value>
...] [force=
<true | false>
] [on=
<XenServer host UUID>
]
Resume the specified VMs.
The VM or VMs on which this operation should be performed are selected using the standard selection
mechanism (see
VM selectors
). Optional arguments can be any number of the
VM parameters
listed at the
beginning of this section.
If the VM is on a shared SR in a pool of hosts, use the
on
argument to specify which host in the pool
on which to start it. By default the system will determine an appropriate host, which might be any of the
members of the pool.
vm-shutdown
vm-shutdown
[
<vm-selector>
=
<vm_selector_value>
...] [force=
<true | false>
]
