[libvirt] Serial connection between guests

Hi, (I'm not subscribed to the list, please keep me on Cc) I'm attempting to get a serial link between two guests, same hypervisor. The only practical way I could find is to add a serial port using a pty to a guest and then manually connecting to the serial (console in my case) of the other guest using socat in the hypervisor. Then it made me think.. we could have this implemented at libvirt level. We could have a serial port on which we choose pty, udp, tcp, etc, and also a serial port from another guest, so that libvirt would handle socat start/stop automatically as both guests come up/down. Maybe libvirt could even do something smarter than that, maybe it can avoid socat somehow. What do you think? My usage is for virtualizing TAHI: http://networktest.sourceforge.net/usage.html I need 2 ethernet links plus a serial one, which TAHI can't break while running the tests. I didn't think this regarding multi-platform & all.. just sharing the idea/need. Thanks, Marcelo
