+# @xen-orchestra/emit-async [![Build Status](https://travis-ci.org/${pkg.shortGitHubPath}.png?branch=master)](https://travis-ci.org/${pkg.shortGitHubPath})
+
+> ${pkg.description}
+
+## Install
+
+Installation of the [npm package](https://npmjs.org/package/@xen-orchestra/emit-async):
+
+```
+> npm install --save @xen-orchestra/emit-async
+```
+
+## Usage
+
+```js
+import EE from 'events'
+import emitAsync from '@xen-orchestra/emit-async'
+
+const ee = new EE()
+ee.emitAsync = emitAsync
+
+ee.on('start', async function () {
+  // whatever
+})
+
+// similar to EventEmmiter#emit() but returns a promise which resolves when all
+// listeners have resolved
+await ee.emitAsync('start')
+
+// by default, it will rejects as soon as one listener reject, you can customise
+// error handling though:
+await ee.emitAsync({
+  onError (error) {
+    console.warn(error)
+  }
+}, 'start')
+```
+
+## Development
+
+```
+# Install dependencies
+> yarn
+
+# Run the tests
+> yarn test
+
+# Continuously compile
+> yarn dev
+
+# Continuously run the tests
+> yarn dev-test
+
+# Build for production (automatically called by npm install)
+> yarn build
+```
+

+# @xen-orchestra/log [![Build Status](https://travis-ci.org/vatesfr/xen-orchestra.png?branch=master)](https://travis-ci.org/vatesfr/xen-orchestra)
+
+> ${pkg.description}
+
+## Install
+
+Installation of the [npm package](https://npmjs.org/package/@xen-orchestra/log):
+
+```
+> npm install --save @xen-orchestra/log
+```
+
+## Usage
+
+Everywhere something should be logged:
+
+```js
+import createLogger from '@xen-orchestra/log'
+
+const log = createLogger('my-module')
+
+log.debug('only useful for debugging')
+log.info('this information is relevant to the user')
+log.warn('something went wrong but did not prevent current action')
+log.error('something went wrong')
+log.fatal('service/app is going down')
+```
+
+Then, at application level, configure the logs are handled:
+
+```js
+import { configure, catchGlobalErrors } from '@xen-orchestra/log/configure'
+import transportConsole from '@xen-orchestra/log/transports/console'
+import transportEmail from '@xen-orchestra/log/transports/email'
+
+const transport = transportEmail({
+  service: 'gmail',
+  auth: {
+    user: 'jane.smith@gmail.com',
+    pass: 'H&NbECcpXF|pyXe#%ZEb'
+  },
+  from: 'jane.smith@gmail.com',
+  to: [
+    'jane.smith@gmail.com',
+    'sam.doe@yahoo.com'
+  ]
+})
+
+configure([
+  {
+    // if filter is a string, then it is pattern
+    // (https://github.com/visionmedia/debug#wildcards) which is
+    // matched against the namespace of the logs
+    filter: process.env.DEBUG,
+
+    transport: transportConsole()
+  },
+  {
+    // only levels >= warn
+    level: 'warn',
+
+    transport
+  }
+])
+
+// send all global errors (uncaught exceptions, warnings, unhandled rejections)
+// to this transport
+catchGlobalErrors(transport)
+```
+
+### Transports
+
+#### Console
+
+```js
+import transportConsole from '@xen-orchestra/log/transports/console'
+
+configure(transports.console())
+```
+
+#### Email
+
+Optional dependency:
+
+```
+> yarn add nodemailer pretty-format
+```
+
+Configuration:
+
+```js
+import transportEmail from '@xen-orchestra/log/transports/email'
+
+configure(transportEmail({
+  service: 'gmail',
+  auth: {
+    user: 'jane.smith@gmail.com',
+    pass: 'H&NbECcpXF|pyXe#%ZEb'
+  },
+  from: 'jane.smith@gmail.com',
+  to: [
+    'jane.smith@gmail.com',
+    'sam.doe@yahoo.com'
+  ]
+}))
+```
+
+#### Syslog
+
+Optional dependency:
+
+```
+> yarn add split-host syslog-client
+```
+
+Configuration:
+
+```js
+import transportSyslog from '@xen-orchestra/log/transports/syslog'
+
+// By default, log to udp://localhost:514
+configure(transportSyslog())
+
+// But TCP, a different host, or a different port can be used
+configure(transportSyslog('tcp://syslog.company.lan'))
+```
+
+## Development
+
+```
+# Install dependencies
+> yarn
+
+# Run the tests
+> yarn test
+
+# Continuously compile
+> yarn dev
+
+# Continuously run the tests
+> yarn dev-test
+
+# Build for production (automatically called by npm install)
+> yarn build
+```

 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.

-### Preparation
 
-1. create a cont. rep job to a non-distant SR (even the SR where the VM currently is). Do NOT enable the job during creation.
-1. manually start the first replication (only the first)
-1. when finished, export the replicated VM (via XOA or any other means, doesn't matter how you get your XVA file)
-1. import the replicated VM on your distant destination
-1. you can now remove your local replicated copy
+### Job creation
 
-### Modifications
+Create the Continuous Replication backup job, and leave it disabled for now. On the main Backup-NG page, note its identifiers, the main `backupJobId` and the ID of one on the schedules for the job, `backupScheduleId`.
 
-In your source host:

-  * Recreate the correct param: `xe vm-param-set uuid=<OriginalVM_UUID> other-config:xo:base_delta:<destination_SR_UUID>=<VM_snapshot_UUID>`

+### Set up metadata
+
+The XOA backup system requires metadata to correctly associate the source snapshot and the target VM to the backup job. We're going to use the `xo-cr-seed` utility to help us set them up.
+
+First install the tool (all the following is done from the XOA VM CLI):
 
 ```
-xe vm-param-set blocked-operations:start uuid=<DestinationVM_UUID>
+npm i -g xo-cr-seed
 ```
 
-### Enable
+Here is an example of how the utility expects the UUIDs and info passed to it:

+
+xo-cr-seed v0.2.0
+```
+Putting it altogether and putting our values and UUID's into the command, it will look like this (it is a long command):
+```
