Hi Paolo, I found a problem that a virtio-scsi disk gets offline during mkfs. The scsi disk is of 100G or bigger, and the corresponding image is a freshly created qcow2 image. If the disk is small enough, or not freshly created, the problem doesn't appear.
Hi Hu,I cannot reproduce this with a 100G qcow2 image (created with "qemu-img create scsi.qcow2 100G" just before launching the host), with a partition starting at sector 2048 and extending to the end of the disk. mkfs (ext4) takes less than 1 minute and extends the qcow2 file to a little less than 2 gigs.
Can you send the partition table ("file -s /dev/sda" should be enough) and any output you get from the dmesg?
