[libvirt] [PATCH 0/2] qemu: Add pre-migration hook

Current dxml parameter of virDomainMigrate{,ToURI}2 requires the caller to have deep knowlege of the environment on the target machine. In some cases, this may be impractical or even impossible to achieve. By adding per-migration hook which may filter incoming domain XML and change it appropriately called during the Prepare phase the destination host may filter incoming domain XMLs and change them to fit local environment. For example, such hook may relocate disk images. The hook is not allowed to make guest-visible changes to a domain XML.
