With e.g.:
<serial type='tcp'>
<source mode='bind' host='127.0.0.1' service='4444'/>
<protocol type='telnet'/>
<target port='0'/>
</serial>
You currently get:
Unknown option: listen
qemu: could not open serial device 'telnet:127.0.0.1:4444,listen'
With the telnet protocol, qemu expects "server" as an option
rather than "listen".

Not that I'm qualified to comment on this but a
testcase in
tests/qemuxml2argv* would prevent breaking this in the future.

The test case is only as good as the person writing the test. We have an
existing test case for Telnet support which is happily validating that we
are generating the incorrect syntax.

ACK, but can you also fix the test case for this to match before
committing. We're currently validating that it is 'listen' :-)

Thanks, fixed and committed.
