This is what the most recent qemu produces:
bus: pci
type PCI
dev: virtio-serial-pci, id "virtio-serial0"
ioeventfd = on
vectors = 2
class = 0x780
indirect_desc = on
event_idx = on
max_ports = 31
addr = 03.0
romfile = <null>
rombar = 1
multifunction = off
command_serr_enable = on
class Class 0780, addr 00:03.0, pci id 1af4:1003 (sub 1af4:0003)
bar 0: i/o at 0xffffffffffffffff [0x1e]
bar 1: mem at 0xffffffffffffffff [0xffe]
bus: virtio-bus
type virtio-pci-bus
dev: virtio-serial-device, id ""
max_ports = 31
bus: virtio-serial0.0
type virtio-serial-bus
dev: virtserialport, id "channel0"
chardev = charchannel0
nr = 1
name = "com.redhat.rhevm.vdsm"
port 1, guest off, host off, throttle off
The device layout is new, the bus name is old - "virtio-serial0.0",
everything should be ok now.
