[KVM-AUTOTEST,3/6] KVM test: add a function that translates user specified paths to real ones

Commit Message

Michael Goldish Aug. 9, 2009, 4:33 p.m. UTC

If a user specified path is an absolute one, it is returned as is.
If it's relative, it's appended to a certain base path.

This function is meant to allow framework and test code to treat all user
specified paths equally.
