[one-users] Raw attributes not getting resolved

I'm attempting to configure a console for my vm so I can connect to it via
"virsh", but I believe I am screwing up the declaration in the template.
<quote>
RAW = [ type = "kvm", data = "<console type=\"stdio\"><target
port=\"1\"/></console>" ]
</quote>
results in the following deployment descriptor:
<domain type='kvm'>
<name>one-31</name>
<memory>262144</memory>
<os>
<type>hvm</type>
<boot dev='hd'/>
</os>
<devices>
<emulator>/usr/bin/kvm</emulator>
<disk type='file' device='disk'>
<source file='/opt/nebula/ONE/var//31/images/disk.0'/>
<target dev='vda' bus='virtio'/>
</disk>
<interface type='bridge'>
<source bridge='br0'/>
<model type='virtio'/>
</interface>
<interface type='bridge'>
<source bridge='br0'/>
<mac address='00:03:0a:00:01:04'/>
<model type='virtio'/>
</interface>
</devices>
<features>
<pae/>
<acpi/>
</features>
<console type="stdio"><target port="1"/></console>
</domain>
But when I attempt to connect to the console I get the following error:
<quote>
sudo virsh console one-31
[sudo] password for xxxx:
Connecting to uri: qemu:///system
No console available for domain
</quote>
virsh dumpxml shows the following:
<domain type='kvm' id='13'>

As you can see no console element.
If I redefine the domain and add the following (via virsh), I can connect
successfully.
<domain type='kvm'>
<name>one-31</name>
<uuid>89e69209-ba37-8ccf-832f-f637ab753710</uuid>
<memory>262144</memory>
<currentMemory>262144</currentMemory>
<vcpu>1</vcpu>
<os>
<type arch='i686' machine='pc-0.11'>hvm</type>
<boot dev='hd'/>
</os>
<features>
<acpi/>
<pae/>
</features>
<clock offset='utc'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>destroy</on_crash>
<devices>
<emulator>/usr/bin/kvm</emulator>
<disk type='file' device='disk'>
<source file='/opt/nebula/ONE/var//31/images/disk.0'/>
<target dev='vda' bus='virtio'/>
</disk>
<interface type='bridge'>
<mac address='52:54:00:9c:c1:cb'/>
<source bridge='br0'/>
<target dev='vnet4'/>
<model type='virtio'/>
</interface>
<interface type='bridge'>
<mac address='00:03:0a:00:01:04'/>
<source bridge='br0'/>
<target dev='vnet5'/>
<model type='virtio'/>
</interface>
<serial type='pty'>
<source path='/dev/pts/5'/>
<target port='0'/>
</serial>
<console type='pty' tty='/dev/pts/5'>
<source path='/dev/pts/5'/>
<target port='0'/>
</console>
</devices>
</domain>
So I tried passing in the following as RAW attributes:
RAW = [ type = "kvm",
data = "<serial type=\"pty\"><source
path=\"/dev/pts/5\"/><target port=\"0\"/></serial><console type=\"pty\"
tty=\"/dev/pts/5\"><source path=\"/dev/pts/5\"/><target
port=\"0\"/></console>" ]
The above results in the following deployment descriptor being generated:
<domain type='kvm'>
<name>one-32</name>
<memory>262144</memory>
<os>
<type>hvm</type>
<boot dev='hd'/>
</os>
<devices>
<emulator>/usr/bin/kvm</emulator>
<disk type='file' device='disk'>
<source file='/opt/nebula/ONE/var//32/images/disk.0'/>
<target dev='vda' bus='virtio'/>
</disk>
<interface type='bridge'>
<source bridge='br0'/>
<model type='virtio'/>
</interface>
<interface type='bridge'>
<source bridge='br0'/>
<mac address='00:03:0a:00:01:04'/>
<model type='virtio'/>
</interface>
</devices>
<features>
<pae/>
<acpi/>
</features>
<serial type="pty"><source path="/dev/pts/5"/><target
port="0"/></serial><console type="pty" tty="/dev/pts/5"><source
path="/dev/pts/5"/><target port="0"/></console>
</domain>
But still cannot connect to the console. The dumpxml (via virsh) reveals the
following:
oneadmin at uecB:~/domainTemplates$ virsh dumpxml one-32
Connecting to uri: qemu:///system
<domain type='kvm' id='15'>
<name>one-32</name>

<memory>262144</memory>
<currentMemory>262144</currentMemory>
<vcpu>1</vcpu>
<os>
<type arch='i686' machine='pc-0.11'>hvm</type>
<boot dev='hd'/>
</os>
<features>

</devices>

</domain>
As you can see, the RAW attributes did not get generated here. Any idea what
is going on and how I can get this resolved.
Also, the documentation at
http://opennebula.org/doku.php?id=documentation:rel1.4:kvmg
<quote>
RAW = [ type = "kvm",
data = "<console type=\"stdio\"><target port=\"1\"></console>" ]
</quote>
causes the deployment to fail with the following error in the vm.log
Thu Feb 4 11:37:59 2010 [VMM][I]: error: Failed to create domain from
/opt/nebula/ONE/var//30/images/deployment.0
Thu Feb 4 11:37:59 2010 [VMM][I]: error: at line 28: Opening and ending tag
mismatch: target line 28 and console
Thu Feb 4 11:37:59 2010 [VMM][I]:
Thu Feb 4 11:37:59 2010 [VMM][I]: ExitCode: 1
Thu Feb 4 11:37:59 2010 [VMM][E]: Error deploying virtual machine
Therefore please update the documentation.
