Could you clarify more about this?
The migration is not supported if using viommu (SMMU QE

tried 4.7-r2 and 4.5-rc1 on D02 board, both have issue.
Since I need kvm specific patch for D02, so it may not freely to switch
to older version.
3. Also test with ext4, disabling journal
mkfs.ext4 -O ^has_journal /dev/sda
Do you have any suggestion?

Here is one question about testing virtio-scsi & vhost-scsi.
I met ext4 error using fileio or iblock.
And after the error, the filesystem can not be remount next time in
guest os except mkfs.ext4 again.
Any suggestions?
Thanks in advance.
Basic steps.
fileio:
mount /dev/sda3 /mnt
dd if=/dev/zero
