The /root mount introduced for nested VM support shadows any host paths under /root. This breaks systems where the outer VM runs as root and the vsock_test binary path is something like: /root/linux/tools/testing/selftests/vsock/vsock_test Fix this by copying vsock_test into the temporary home directory that gets mounted as /root in the guest, and using a relative path to invoke it.
