[Qemu-devel] Virtual serial logging server?

[Reeted]

Dear all,
please excuse the almost-OT question,

I see various possibilities in quemu-kvm and libvirt for sending virtual 
serial port data to files, sockets, pipes, etc on the host.
In particular, the TCP socket seems interesting.

Can you suggest a server application to receive all such TCP connections 
and log serial data for many virtual machines at once?

In particular I would be interested in something with quotas, i.e. 
something that deletes old lines from the logs of a certain VM when the 
filesystem space occupied by the serial logs of such VM gets over a 
certain amount of space. So that the log space for other VMs is not 
starved in case one of them loops.

Thank you
R.
