I am trying to migrate a VMware guest to KVM. I have the .vmdk file which I convert to qcow2 format using qemu-img convert.

The next step is to import the new img file. 

If I use virt-install --import <guest config options> it all works fine. 
But when I try the same think using the libvirt API I get the "no boot disk found" message when starting the vm.

When importing the VM through the libvirtAPI, I use the same xml description virsh outputs (dumpxml) after initially doing the import.

xml - the description I got using virsh xmldump <domain name>

xmlDesx = xml
conn.defineXML(xmlDesc)

One other important aspect is I am using a directory storage pool to store all my volumes (.img files). 
When I use virsh to import the vm, the storage pool recognizes the new volume (the .img file I converted from the .vmdk file). But when I use the libvirtAPI, it does not.

So my guess is that because the storage pool does not see the new volume when I import the vm is the reason I get the "no boot disk found message".

Is there a way to tell the storage pool about the new volume? 
What exactly does virsh do and I am not ?

Thanks,
Andrei
