Hi,
thanks for your reply ,
The content of the deployment.0 file is as follow :
-----------
> cat /data1/opennebula/var/704/deployment.0
<domain type='kvm'>
<name>one-704</name>
<memory>1048576</memory>
<os>
<type>hvm</type>
<boot dev='hd'/>
</os>
<devices>
<emulator>/usr/bin/kvm</emulator>
<disk type='file' device='disk'>
<source
file='/data1/opennebula/var//704/images/disk.0'/>
<target dev='hda'/>
</disk>
<disk type='file' device='disk'>
<source
file='/data1/opennebula/var//704/images/disk.1'/>
<target dev='hde'/>
</disk>
<interface type='bridge'>
<source bridge='br3'/>
<mac address='02:00:9d:9f:f9:86'/>
</interface>
<interface type='bridge'>
<source bridge='br0'/>
<mac address='02:00:0a:8e:b4:0a'/>
</interface>
<graphics type='vnc' listen='127.0.0.1' port='-1'/>
</devices>
<features>
<acpi/>
</features>
</domain>
Now, when I added " DISK = [ IMAGE_ID = 72, TARGET=hdb ]" to my VM
template. I succeed to create the VM. Its state is « runn ».
But when i have access to the VM and i check partition disk , I don't find
any mounting to the DATABLOCK Disk....
