Currently we spawn couple of binaries in our test suite. Moreover, we provide some spoofed versions of system binaries hoping that those will be executed instead of the system ones. For instance, for testing SSH socket we have written our own ssh binary for producing predictable results. We certainly don't want to execute the system ssh binary. However, in order to prefer our binaries over system ones, we need to set PATH environment variable. But this is done only at the Makefile level. So if anybody runs a test by hand that expects our spoofed binary, the test ends up executing real system binaries. This is not good. In fact, it's terribly wrong. The fix lies in a small trick - putting our build directory at the beginning of the PATH environment variable in each test. Hopefully, since every test has this VIRT_TEST_MAIN* wrapper, we can fix this at a single place. Moreover, while this removes setting PATH for our tests written in bash, it's safe as we are not calling anything ours that would require PATH change there.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
