Hi all,
When we use the latest version of QEMU to build ovirt, we get this error reported from libvirt.
What QEMU commit is this? It might have been fixed already. Paolo
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. :) --Li
