If you create a bcache device with caching device and backing device on virtio disks, it will let you do your work until you mount it where it crashes the virtual machine (virtual machine is utopic, host is trusty).
For example:
if your backing device is /dev/vdb, and your caching device is /dev/vdc:
sudo make-bcache -B /dev/vdc -C /dev/vdb --writeback
is ok
mkfs.ext4 /dev/bcache0 -L bcache-test
is ok
but
mount /dev/bcache0 /media/bcache
make it crash, if I remember well one time I had a few seconds before crash.
qemu-system-x86 is version 2.0.0+dfsg-2ubuntu1.2 |

Re-installing, and using IDE virtual interface seems to create and mount the bcache device is ok.
After bcache created an mounted successfully with IDE interfaces, switching to SATA, SCSI, and USB with booting and mounting seemed ok. |
