[Bug 832507] Re: console.log grows indefinitely

[Robie Basak]

conserver is in Debian non-free, and thus unsuitable.

conserver would still needed to receive the log output from qemu via a
FIFO or similar, and this introduces the problem of what qemu should do
when it is blocked on writing to conserver, which is where I think my
previous patch failed (and I did warn about this in advance!). And
conserver only supports log rotation, rather than a ringbuffer. This
would make get_console_output useless if it was requested just after the
log rotated, without extra complex glue. The code to work around these
issues would be more complex than just not using conserver, IMHO.

In any case, conserver is massive overkill for the need here, which is
to have a simple ringbuffered console log.
