If you want to add a **disk** to an **existing VM** you can edit the XML configuration file ( Settings->XML )
{{:vmxml.jpg?nolink&400|}}

Add under the <devices> section:
<file>
<disk type='block' device='disk'>
  <driver name='qemu' type='raw'/>
  <source dev='/dev/sdb'/>
  <target dev='sdb' bus='scsi'/>
  <address type='drive' controller='0' bus='0' target='0' unit='5'/>
</disk>
</file>
**NB: Replace sdb with the correct drive!**
</WRAP>
<WRAP round tip 75%>
If you want to add a **NIC** to an **existing VM** you can edit the XML configuration file ( Settings->XML )
{{:vmxml.jpg?nolink&400|}}

Add the new bridge interface on Nethserver gui and WebVirtMgr and add under the <devices> section:
<file>
<interface type='bridge'>
  <mac address='52:54:00:12:34:56'/>
  <source bridge='br1'/>
  <model type='virtio'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/>
</interface>

<WRAP left round alert 75%>
**Add a password to protect the vnc connection.**

Edit the config xml (Settings->XML) adding passwd='your_password' in the "<graphics type" section.

Example:
    <graphics type='vnc' port='5902' autoport='yes' listen='0.0.0.0' keymap='it' passwd='your pssword'>
</WRAP>




{{:vmstart.jpg?nolink&400|}}

Go to power and press "start!"

==== 10) Web Console====
You can access the VM with the webconsole (Access->Console click "Console" button)

{{:vmconsole.jpg?nolink&400|}}

<WRAP round tip 75%>
You can use any VNC client (like Vinagre on linux) instead the webconsole.
See on witch port the vnc server is running by finding it in the xml config(Settings->xml).

example:
    <graphics type='vnc' port='5900' autoport='yes' listen='0.0.0.0' keymap='it'>
You can connect to <your_NS_IP>::5900
