I wouldn't call this error message vague at all: it tells you exactly
what the problem is, namely that libvirt needs the 'swtpm' command
for your configuration but the latter is not available :)

Unfortunately it looks like swtpm it's not packaged for Debian, so
I'm afraid the solution is not just a simple apt-get away :(
