Public bug reported:
How to replicate:
1. Install libvirt, libvirt-daemon-driver-storage-zfs and virt-manager
2. Create a zfs pool
# zpool create -oashift=12 zfs /dev/sdb
# zfs set compression=lz4 zfs
# zfs create zfs/images
# virsh pool-define-as --name zfs --source-name zfs/images --type zfs
3. Create a volume in that pool
root@beaver:~# virsh vol-create-as --pool zfs --name vol1 --capacity 1G
Vol vol1 created
root@beaver:~# virsh vol-list --pool zfs
Name Path
------------------------------------------------------------------------------
vol1 /dev/zvol/zfs/images/vol1
4. Start virt-manager (even as a non-root user)
5. Immediately re-list the volumes from virsh:
root@beaver:~# virsh vol-list --pool zfs
Name Path
------------------------------------------------------------------------------
root@beaver:~#
All zfs volumes have been forgotten!! Fortunately they still exist in
zfs:
root@beaver:~# zfs list
NAME USED AVAIL REFER MOUNTPOINT
zfs 1.03G 8.59G 96K /zfs
zfs/images 1.03G 8.59G 96K /zfs/images
zfs/images/vol1 1.03G 9.63G 56K -
I think virt-manager is supposed to play nicely with zfs:
* You can create a zfs pool successfully in the GUI
* You can click to create a zfs volume. It actually creates the underlying
zvol (as shown by "zfs list")
* But every time you do any action in virt-manager, even just clicking the
Refresh button on the list of volumes, all volumes disappear from libvirt.
root@beaver:~# virsh vol-list --pool zfs
Name Path
------------------------------------------------------------------------------
vol1 /dev/zvol/zfs/images/vol1
root@beaver:~#
<<< click the Refresh button >>>
root@beaver:~# virsh vol-list --pool zfs
Name Path
------------------------------------------------------------------------------
root@beaver:~#
