The {PVE} node management tool (`pvenode`) allows you to control node specific
settings and resources.

Currently `pvenode` allows you to set a node's description, run various
bulk operations on the node's guests, view the node's task history, and
manage the node's SSL certificates, which are used for the API and the web GUI
through `pveproxy`.

Examples
~~~~~~~~

.Install an externally provided certificate

`pvenode cert set certificate.crt certificate.key -force`

Both files need to be PEM encoded. `certificate.key` contains the private key
and `certificate.crt` contains the whole certificate chain.

.Setup ACME account and order a certificate for the local node.

-----
pvenode acme account register default mail@example.invalid
pvenode config set --acme domains=example.invalid
pvenode acme cert order
systemctl restart pveproxy

Wake-on-LAN
~~~~~~~~~~~
Wake-on-LAN (WoL) allows you to switch on a sleeping computer in the network, by
sending a magic packet. At least one NIC must support this feature, and the
respective option needs to be enabled in the computer's firmware (BIOS/UEFI)
configuration. The option name can vary from 'Enable Wake-on-Lan' to
'Power On By PCIE Device'; check your motherboard's vendor manual, if you're
unsure. `ethtool` can be used to check the WoL configuration of `<interface>`
by running:

----
ethtool <interface> | grep Wake-on
----

`pvenode` allows you to wake sleeping members of a cluster via WoL, using the
command:

----
pvenode wakeonlan <node>
----

This broadcasts the WoL magic packet on UDP port 9, containing the MAC address
of `<node>` obtained from the `wakeonlan` property. The node-specific
`wakeonlan` property can be set using the following command:

----
pvenode config set -wakeonlan XX:XX:XX:XX:XX:XX
----

The interface via which to send the WoL packet is determined from the default
route. It can be overwritten by setting the `bind-interface` via the following
command:

----
pvenode config set -wakeonlan XX:XX:XX:XX:XX:XX,bind-interface=<iface-name>
----

The broadcast address (default `255.255.255.255`) used when sending the WoL
packet can further be changed by setting the `broadcast-address` explicitly
using the following command:

----
pvenode config set -wakeonlan XX:XX:XX:XX:XX:XX,broadcast-address=<broadcast-address>
----

Task History
~~~~~~~~~~~~

When troubleshooting server issues, for example, failed backup jobs, it can
often be helpful to have a log of the previously run tasks. With {pve}, you can
access the nodes's task history through the `pvenode task` command.

You can get a filtered list of a node's finished tasks with the `list`
subcommand. For example, to get a list of tasks related to VM '100'
that ended with an error, the command would be:

----
pvenode task list --errors --vmid 100
----

The log of a task can then be printed using its UPID:

----
pvenode task log UPID:pve1:00010D94:001CA6EA:6124E1B9:vzdump:100:root@pam:
----


Bulk Guest Power Management
~~~~~~~~~~~~~~~~~~~~~~~~~~~

In case you have many VMs/containers, starting and stopping guests can be
carried out in bulk operations with the `startall` and `stopall` subcommands of
`pvenode`.  By default, `pvenode startall` will only start VMs/containers which
have been set to automatically start on boot (see
xref:qm_startup_and_shutdown[Automatic Start and Shutdown of Virtual Machines]),
however, you can override this behavior with the `--force` flag. Both commands
also have a `--vms` option, which limits the stopped/started guests to the
specified VMIDs.

For example, to start VMs '100', '101', and '102', regardless of whether they
have `onboot` set, you can use:

----
pvenode startall --vms 100,101,102 --force
----

To stop these guests (and any other guests that may be running), use the
command:

----
pvenode stopall
----

NOTE: The stopall command first attempts to perform a clean shutdown and then
waits until either all guests have successfully shut down or an overridable
timeout (3 minutes by default) has expired. Once that happens and the
force-stop parameter is not explicitly set to 0 (false), all virtual guests
that are still running are hard stopped.


[[first_guest_boot_delay]]
First Guest Boot Delay
~~~~~~~~~~~~~~~~~~~~~~

In case your VMs/containers rely on slow-to-start external resources, for
example an NFS server, you can also set a per-node delay between the time {pve}
boots and the time the first VM/container that is configured to autostart boots
(see xref:qm_startup_and_shutdown[Automatic Start and Shutdown of Virtual Machines]).

You can achieve this by setting the following (where `10` represents the delay
in seconds):

----
pvenode config set --startall-onboot-delay 10
----


Bulk Guest Migration
~~~~~~~~~~~~~~~~~~~~

In case an upgrade situation requires you to migrate all of your guests from one
node to another, `pvenode` also offers the `migrateall` subcommand for bulk
migration. By default, this command will migrate every guest on the system to
the target node. It can however be set to only migrate a set of guests.

For example, to migrate VMs '100', '101', and '102', to the node 'pve2', with
live-migration for local disks enabled, you can run:

----
pvenode migrateall pve2 --vms 100,101,102 --with-local-disks
----

// TODO: explain node shutdown (stopall is used there) and maintenance options
