Found another one, though it's an old one (so not really a regression): QEMU doesn't catch -EPIPE for short-lived guest processes and disconnected host chardevs. This is also described in https://bugzilla.redhat.com/show_bug.cgi?id=621484. To reproduce this issue: start qemu, boot guest connect netcat to the unix socket echo some chars to /dev/virtio-ports/$name watch them appear in netcat stop netcat, restart it echo some chars again watch them *not* appear BTW I've just put up this feature page on the wiki with status, testing and known bugs sections, which describe the two current known bugs. http://wiki.qemu.org/Features/ChardevFlowControl Amit
