Hi all,
When we use the latest version of QEMU to build ovirt,
we get this error reported from libvirt.
qemu-system-ppc64: -device
virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.rhevm.vdsm:
Bus 'virtio-serial0.0' is full
qemu-system-ppc64: -device
virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.rhevm.vdsm:
Bus 'virtio-serial0.0' not found
Libvirt helps create QEMU command line and put virtserialport device to
bus virtio-serial0.0.
For latest version of QEMU, the bus type is changed.

But we tried to replace virtio-serial0.0 with virtio-serial-bus.0,
SLOF crashes. It still doesn't work at all.
Does anyone know how to use virtserialport in QEMU command line?
If configuration is changed in QEMU, libvirt also needs to change it
accordingly.
Thanks. :)
