[Qemu-devel] Would virtio support 64 bit address for vring virtqueue?

[Xie, Huawei]

I am developing virtio user space poll mode network driver. We allocate vring 
physical memory from huge page. On VMs with less than 4GB  memory, it works 
well.  But on VMs with like 8GB memory, huge page are all allocated from high 
end memory.
So would virtio support 64bit address for vring virtqueue?

Thanks
