[libvirt] [PATCH 0/7] virStorageVolCreateXMLFrom API

[Cole Robinson]

Hi all,

The following patches implement a new API call: virStorageVolCreateXMLFrom.

virStorageVolPtr
virStorageVolCreateXMLFrom(virStoragePoolPtr pool,
                           const char *xmldesc,
                           unsigned int flags,
                           virStorageVolPtr clonevol)

Arguments function similar to the regular volume create API, except the
parameter 'clonevol' is used as the input source. The API allows for
volume cloning, possibly across pools, or within the same pool but converting
volume formats.

Tests I performed (and ensured that a VM booted without complaints from the
new image):

Raw -> Raw (with successful sparse detection)
Raw -> QCOW2
QCOW2 -> Raw
QCOW2 -> QCOW2
QCOW2 -> VMDK
Raw partition ('disk' volume) -> Raw file

Thanks,
Cole
