feat(@xen-orchestra/cron): 1.0.4

Fixes xoa-support#1676

For now, the delay is set to 10s which is the duration used by xo-web's
subscription, which makes it enough to make it independent of the number of
clients.

In the future, this should probably be longer and configurable, but this
requires invalidating the cache in case of changes (creation/deletion of
backups) and explicit requests from the users, which will be implemented in
another PR.

-This means your previous VM disks and snapshots should be "merged" (*coalesced* in the XenServer world) before we can take a new snapshot.

Otherwise, this will lead to catastrophic consequences. Xen Orchestra is the **only** XenServer/XCP backup product dealing with this.
+Backup jobs regularly delete snapshots.

Check the problematic SR and make sure it has enough free space, generally 30% or more free is recommended depending on VM size. You can check if this is the issue by searching `SMlog` with `grep -i coales /var/log/SMlog` (you may have to look at previous logs such as `SMlog.1`).
 
 You can check if a coalesce job is currently active by running `ps axf | grep vhd` on the XenServer host and looking for a VHD process in the results (one of the resulting processes will be the grep command you just ran, ignore that one).  
 
-If you don't see any running coalesce jobs, and can't find any other reason that XenServer has not started one, you can attempt to make it start a coalesce job by rescanning the SR. This is harmless to try, but will not always result in a coalesce. Visit the problematic SR in the XOA UI, then click the "Rescan All Disks" button towards the top right: it looks like a refresh circle icon. This should begin the coalesce process - if you click the Advanced tab in the SR view, the "disks needing to be coalesced" list should become smaller and smaller.

+

+Putting it altogether and putting our values and UUID's into the command, it will look like this (it is a long command):
+```

+```
+
+### Finished
+
+Your backup job should now be working correctly! Manually run the job the first time to check if everything is OK. Then, enable the job. **Now, only the deltas are sent, your initial seed saved you a LOT of time if you have a slow network.**

+# Emergency Shutdown
+
+If you have a UPS for your hosts, and lose power, you may have a limited amount of time to shut down all of your VM infrastructure before the batteries run out. If you find yourself in this situation, or any other situation requiring the fast shutdown of everything, you can use the **Emergency Shutdown** feature.
+
+## How to activate
+On the host view, clicking on this button will trigger the  _Emergency Shutdown_ procedure:
+
+![](./assets/e-shutdown-1.png)
+
+1.  **All running VMs will be suspended**  (think of it like "hibernate" on your laptop: the RAM will be stored in the storage repository).
+2.  Only after this is complete, the host will be halted.
+
+Here, you can see the running VMs are being suspended:
+
+![](./assets/e-shutdown-2.png)
+
+And finally, that's it. They are cleanly shut down with the RAM saved to disk to be resumed later:
+
+![](./assets/e-shutdown-3.png)
+
+Now the host is halted automatically.
+
+## Powering back on
+When the power outage is over, all you need to do is:
+
+1.  Start your host.
+2.  All your VMs can be resumed, your RAM is preserved and therefore your VMs will be in the exact same state as they were before the power outage.

+# Metadata backup
+
+> WARNING: Metadata backup is an experimental feature. Unexpected issues are possible, but unlikely.
+
+## Introduction
+
+XCP-ng and Citrix Hypervisor (Xenserver) hosts use a database to store metadata about VMs and their associated resources such as storage and networking. Metadata forms this complete view of all VMs available on your pool. Backing up the metadata of your pool allows you to recover from a physical hardware failure scenario in which you lose your hosts without losing your storage (SAN, NAS...).
+
+In Xen Orchestra, Metadata backup is divided into two different options:
+
+* Pool metadata backup
+* XO configuration backup
+
+### Performing a backup
+
+In the backup job section, when creating a new backup job, you will now have a choice between backing up VMs and backing up Metadata:
+![](./assets/metadata-1.png)
+
+When you select Metadata backup, you will have a new backup job screen, letting you choose between a pool metadata backup and an XO configuration backup (or both at the same time):
+
+![](./assets/metadata-2.png)
+
+Define the name and retention for the job.
+
+![](./assets/metadata-3.png)
+
+Once created, the job is displayed with the other classic jobs.
+
+![](./assets/metadata-4.png)
+
+
+### Performing a restore
+
+> WARNING: restoring pool metadata completely overwrites the XAPI database of a host. Only perform a metadata restore if it is a new server with nothing running on it (eg replacing a host with new hardware).
+
+If you browse to the Backup NG Restore panel, you will now notice a Metadata filter button:
+
+![](./assets/metadata-5.png)
+
+If you click this button, it will show you Metadata backups available for restore:
+
+![](./assets/metadata-6.png)
+
+You can see both our Xen Orchestra config backup, and our pool metadata backup. To restore one, simply click the blue restore arrow, choose a backup date to restore, and click OK:

+# SDN Controller
+
+> SDN Controller is available in XOA 5.44 and higher
+
+The SDN Controller enables a user to **create pool-wide and cross-pool** (since XOA 5.48.1) **private networks**.
+
+![](./assets/sdn-controller.png)
+
+## How does it work?
+
+Please read the [dedicated devblog on the SDN Controller](https://xen-orchestra.com/blog/xo-sdn-controller/) and its [extension for cross-pool private networks](https://xen-orchestra.com/blog/devblog-3-extending-the-sdn-controller/).
+
+## Usage
+
+### Network creation
+
+In the network creation view:
+- Select a `pool`
+- Select `Private network`
+- Select an interface on which to create the network's tunnels
+- Select the encapsulation: a choice is offered between `GRE` and `VxLAN`, if `VxLAN` is chosen, then port 4789 must be open for UDP traffic on all the network's hosts (see [the requirements](#vxlan))
+- Choose if the network should be encrypted or not (see [the requirements](#encryption) to use encryption)
+- Select other `pool`s to add them to the network if desired
+  - For each added `pool`: select an interface on which to create the tunnels
+- Create the network
+- Have fun! ☺
+
+***NB:***
+- All hosts in a private network must be able to reach the other hosts' management interface.
+> The term ‘management interface’ is used to indicate the IP-enabled NIC that carries the management traffic.
+- Only 1 encrypted GRE network and 1 encrypted VxLAN network per pool can exist at a time due to Open vSwitch limitation.
+
+### Configuration
+
+Like all other xo-server plugins, it can be configured directly via
+the web interface, see [the plugin documentation](https://xen-orchestra.com/docs/plugins.html).
+
+The plugin's configuration contains:
+- `cert-dir`: The path where the plugin will look for the certificates to create SSL connections with the hosts.
+If none is provided, the plugin will create its own self-signed certificates.
+- `override-certs`: Enable to uninstall the existing SDN controller CA certificate in order to replace it with the plugin's one.
+
+## Requirements
+
+### VxLAN
+
+- On XCP-ng prior to 7.6:
+  - To be able to use `VxLAN`, the following line needs to be added, if not already present, in `/etc/sysconfig/iptables` of all the hosts where `VxLAN` is wanted: `-A xapi-INPUT -p udp -m conntrack --ctstate NEW -m udp --dport 4789 -j ACCEPT`
+
+### Encryption
+
+> Encryption is not available prior to 8.0.
+
+- On XCP-ng 8.0:
+  - To be able to encrypt the networks, `openvswitch-ipsec` package must be installed on all the hosts:
+    - `yum install openvswitch-ipsec --enablerepo=xcp-ng-testing`
+    - `systemctl enable ipsec`
+    - `systemctl enable openvswitch-ipsec`
+    - `systemctl start ipsec`
