[libvirt] [PATCH 2/3] Remove virFileAbsPath() from virDomainSave*() and virDomainCoreDump() calls

[Hong Xiang]

Change the semantics of '--file' parameter user provides in cmdline from a
relative/absolute filesystem path to an id which is to be converted in
driver to form a filesystem path.

* src/libvirt.c: remove virFileAbsPath() calls
