Re: [libvirt] [PATCH v2] storage: ZFS support

Implement ZFS storage backend driver. Currently supported only on FreeBSD because of ZFS limitations on Linux. Features supported: - pool-start, pool-stop - pool-info - vol-list - vol-create / vol-delete Pool definition looks like that: <pool type='zfs'> <name>myzfspool</name> <source> <name>actualpoolname</name> </source> </pool> The 'actualpoolname' value is a name of the pool on the system, such as shown by 'zpool list' command. Target makes no sense here because volumes path is always /dev/zvol/$poolname/$volname. Users has to create a pool on his own, this driver doesn't

support pool creation currently. A volume could be used with Qemu by adding an entry like this: <disk type='volume' device='disk'> <driver name='qemu' type='raw'/> <source pool='myzfspool' volume='vol5'/> <target dev='hdc' bus='ide'/> </disk> --- configure.ac | 43 +++++ docs/schemas/storagepool.rng | 20 +++ docs/storage.html.in | 34 ++++ include/libvirt/libvirt.h.in | 1 + po/POTFILES.in | 1 + src/Makefile.am | 8 + src/conf/storage_conf.c | 15 +- src/conf/storage_conf.h | 4 +- src/qemu/qemu_conf.c | 1 + src/storage/storage_backend.c | 6 + src/storage/storage_backend_zfs.c | 329 ++++++++++++++++++++++++++++++++++++++ src/storage/storage_backend_zfs.h | 29 ++++ src/storage/storage_driver.c | 1 + tools/virsh-pool.c | 3 + 14 files changed, 492 insertions(+), 3 deletions(-) create mode 100644 src/storage/storage_backend_zfs.c create mode 100644 src/storage/storage_backend_zfs.h
