Hm, probing with -device '?' will get you the new devices: -device virtio-serial-pci and -device virtserialport are two new devices added (along with -device virtconsole). > If there's a better way to do this, please let me know.

But suggesting -virtioconsole supports multiport is misleading and further usage of -virtioconsole is not to be encouraged as well.. > > > I think you mean -device virtconsole here. > > > > Yeah; thanks.
