Hi, Another thing I'm strugglin with: When creating a new domain from scratch using the proposed XML format in the documentation, everything works fine - basically. A problem that I'd like to solve now is that I would expect to be able to create new volumes within libvirt. I started with a basic XML file in order to define a pool, but virsh told me that creating pools is not supported by the VirtualBox hypervisor. with a dummy UUID, named "default-pool". Next I tried to create a new volume from a XML file, but the only thing I'm getting are segmentation faults. Has anybody used this approach successfully ? Otherwise I assume that I have to create the VDI files manually using VirtualBox GUI/VBoxManage or vboxshell.py. Thanks in advance, Regards, Christian
