I use the command like follows to create vm
nova boot --image 66c6aa5a-ce65-40ca-b0fc-1af18b2f744d --flavor m1.tiny --nic net-id=05233983-9bf6-4ab3-bc82-687d6ab9204d --block-device source=blank,device=vdb,bootindex=1,size=1 cirros
After the vm created, virsh dumpxml vm
i can found only one disk attached to the vm
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2' cache='none'/>
<source file='/opt/stack/data/nova/instances/bf7e6006-393e-4e8c-91d3-a28eee965f79/disk'/>
<target dev='vda' bus='virtio'/>
<alias name='virtio-disk0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</disk>
<disk type='file' device='cdrom'>
<driver name='qemu' type='raw' cache='none'/>
<source file='/opt/stack/data/nova/instances/bf7e6006-393e-4e8c-91d3-a28eee965f79/disk.config'/>
<target dev='hdd' bus='ide'/>
<readonly/>
<alias name='ide0-1-1'/>
<address type='drive' controller='0' bus='1' target='0' unit='1'/>
</disk>
<controller type='usb' index='0'>
<alias name='usb0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x2'/>
</controller>
<controller type='pci' index='0' model='pci-root'>
<alias name='pci.0'/>
</controller>
<controller type='ide' index='0'>
<alias name='ide0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/>
</controller>
In my view, we need to check the params named dest in if it exsit in block_device_mappint_v2
