ok, i'll give it a try. But "make defconfig" will make a new .config. So 
i think there won't ever be any 'y' to give to "make oldconfig"?

anyhow. after "make defconfig" there was no "CONFIG_VIRTIO_BLK" in it. 
But in "make menuconfig" i found and enabled it (also 
CONFIG_VIRTIO_NIC). (maybe some issues of -rc2)

the "vda1" thing i didn't know. thanks. will also give it a try - tomorrow.

Is "virtio" block device replacing SATA/SCSI  - are the  SCSI/SATA 
drivers needed on guest?

thanks
