[libvirt-users] VirtualBox headless

[Guilherme Santos]

My objective is also to run headless virtual machines through libvirt
library.
I am using an Ubuntu 10.04 distro and libvirt 0.9.2.

Before asking you guys about it, I searched on the web and found this:

Unfortunately this isn't working for me.
Following is my XML configuration:

<domain type='vbox'>
  <name>THEDOMAIN</name>
  <uuid>33f6e188-1479-46f4-9d90-4d5a2d3a30f2</uuid>
  <memory>393216</memory>
  <currentMemory>393216</currentMemory>
  <vcpu>1</vcpu>
  <os>
    <type arch='i686'>hvm</type>
    <boot dev='hd'/>
    <boot dev='cdrom'/>
  </os>
  <features>
    <acpi/>
  </features>
  <clock offset='localtime'/>
  <on_poweroff>destroy</on_poweroff>
  <on_reboot>destroy</on_reboot>
  <on_crash>destroy</on_crash>
  <devices>
    <disk type='file' device='disk'>
      <source file='/local/vbox-shared.vdi' />
      <target dev='hda' bus='ide'/>
    </disk>
    <disk type='file' device='cdrom'>
      <source file='/local/ubuntu-11.04-desktop-i386.iso' />
      <target dev='hdc' bus='ide'/>
    </disk>
    <interface type='user'>
      <mac address='08:00:27:9a:d0:63'/>
      <model type='Am79C973'/>
    </interface>
    <input type='mouse' bus='ps2'/>
    <graphics type='rdp' autoport='yes' />
    <video>
      <model type='vbox' vram='12' heads='1'>
        <acceleration accel3d='no' accel2d='no'/>
      </model>
    </video>
  </devices>
</domain>

When I run command

*virsh start THEDOMAIN*

it is popping up the following error message:

*OpenRemoteSession/LaunchVMProcess failed, domain can't be started*

As it wasn't working I also tried other options, but unfortunately, using
all other graphic type options (except for 'spice', which I didn't try) the
GUI is launched.

I don't think I'll be needing a RDP connection, neither anything similar to
that, except if these are necessary to basic management of the vm through
virsh (start, stop, reboot, create and revert snapshots).
Isn't there one simple way to run a virtual machine domain headless without
vnc, spice or rdp servers?
If not, which could be going wrong in my xml configuration?

To help understanding of my desired behavior, what I need is to do through
virsh what can be done using

*VBoxManage startvm THEDOMAIN --headless*

or

*VBoxHeadless startvm THEDOMAIN*,

because will use other hypervisors in the future, so it is a critical thing
to me.

Thanks in advance for the help,

Guilherme Santos
