Hi all,
Hi,
When we use the latest version of QEMU to build ovirt,
we get this error reported from libvirt.
What QEMU commit is this?
b3e6d591b05538056d665572f3e3bbfb3cbb70e7
This commit is from 05/29 no?
there were issues with that. But it should be fixed.
Do you still have the command-line issue with the last git?
See commit 80270a19685dd20eda017b0360c743b3e3ed6f57
Hi Fred,
This patch is to change bus which can be compatible with old version, right?
But I saw the current name is still different from old version.
The current name is: "virtio-serial-bus0.0"
The old version is: "virtio-serial0.0"
Is it possible to change it back to the old name?
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.
Alexey, thanks.
It seems that both of them can be recognized. :)
Thanks. :)

Thanks,
Fred
It might have been fixed already.
Hm. From what I see, it is all correct from the qemu side, the problem is
in libvirt which does not know about "virtio-pci-bus" yet.

virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.rhevm.vdsm:

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. :)
