Hi Bruce and Darren,
We need enable target kernel's CONFIG_SCSI_VIRTIO=y to make native qemu
can boot hdddirect, vmdk, qcow2 and vdi, otherwise, the scsi drive can't
work in qemu since our vm image's root default to /dev/sda2, or we can
change it default to /dev/hda2, then we don't have to make any changes
on kernel, but I prefer scsi since ide is going to be out of date.
The IDE fragment was on for compatibility reasons, but we dropped that
compatibility about a year ago. I was under the impression that we had
fully dropped all the IDE fragments.
I've tried to enable it by menuconfig, it works well, would you please
enable it by default ?
Send a patch to the linux-yocto mailing list to change the virtio configuration
fragment.
You are already set up to test it out, so it is much easier.
I don't see why this shouldn't follow the normal patch flow for configuration
frag changes.
Sorry, the problem was that I didn't know how to send patch for yocto kernel:-).
I will send the patch to linux-yocto.

Cheers,
Bruce

It nearly has no impact on the size.
