Package: virt-manager
Version: 1:2.2.1-5
Severity: normal
Dear Maintainer,
- Creating a new pool led me to Runtime Error: Could not build storage
pool:
unable to control COW flag, not btrfs: Function not implemented
- Clicked on plus (+) button to create a new pool, named the pool,
selected a
path to create the new pool.
- The output was: Could not build storage pool: unable to control COW
flag in
'my/new/pool/path', not btrfs: Function not implemented
We can see a more detailed log here (output of virt-manager --debug --
nofork):
summary=Error creating pool: Could not build storage pool: unable to
control
COW flag on '/home/lramos/VMs', not btrfs: Function not implemented
