To attempt to catch unit tests which accidentally create files in $HOME, or $XDG_RUNTIME_DIR, poison these env vars by pointing them to directories which don't exist. This should give easier to debug test failures. For example: $ VIR_TEST_DEBUG=1 ./qemuhotplugtest Could not initialize HostdevManager - operation failed: Failed to create state dir '/bad-test-used-env-xdg-runtime-dir/libvirt/hostdevmgr' Signed-off-by: Daniel P.
