2014-08-20 10:38:06 Kick In description 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 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.
