[Qemu-devel] sparc64/virtio: unable to init msix vectors to 2

[Mark Cave-Ayland]

Hi all,

When creating a qemu-system-sparc64 machine with a virtio interface, 
both QEMU 2.1.0 and current git master emit the above warning:

$ ./qemu-system-sparc64 -drive file=/tmp/file.txt,if=virtio,index=0 
-nographic
qemu-system-sparc64: -drive file=/tmp/file.txt,if=virtio,index=0: unable 
to init msix vectors to 2

Is this harmless? At a superficial level, the interface seems to work if 
you boot with a virtio-enabled -kernel.


Many thanks,

Mark.
