No clue yet, but interested as well. |

Although I avoid these spaced qcow-files anyway. |
| 15 |
|
| 16 |
I would like to run QEMU/KVM-based VMs on btrfs subvolumes ... I love |
| 17 |
the idea of snapshotting them. Until now I often run them on LVM-LVs |
| 18 |
(as "raw") and use virt-backup (which uses LVM snapshots) to generate |
| 19 |
backups. |
| 20 |
|
| 21 |
That works OK but btrfs-snapshots look and are way more sophisticated, |
| 22 |
I assume. |

I currently move over data from my zfs-pool to a new btrfs pool and |
| 27 |
will remove zfs then from that server. |
