The docs/schemas/storagepool.rng uses 'auto': <define name='sourcefmtlogical'> <optional> <element name='format'> <attribute name='type'> <choice> <value>auto</value> <value>lvm2</value> ... 2. The libvirt API has "unknown" which yes technically wrong. 3. However, we cannot just change the API to use auto... So what happens to existing pools on restarts if we change the libvirt API to use "auto" instead of "unknown"? # virsh pool-list Name State Autostart ------------------------------------------- default active no images active yes LVM_Test active yes test_nfs_pool active no # virsh pool-dumpxml LVM_Test <pool type='logical'> <name>LVM_Test</name> <uuid>c93d091b-2314-4909-8ab1-4559909adcce</uuid> <capacity unit='bytes'>9995026432</capacity> <allocation unit='bytes'>0</allocation> <available unit='bytes'>9995026432</available> <source> <device path='/dev/sda3'/> <name>LVM_Test</name> <format type='unknown'/> ... make the change, install it locally, restart libvirt ... # service libvirtd restart Restarting libvirtd (via systemctl): [ OK ] # virsh pool-list Name State Autostart ------------------------------------------- default active no images active yes test_nfs_pool active no # virsh pool-dumpxml LVM_Test error: failed to get pool 'LVM_Test' error: Storage pool not found: no storage pool with matching name 'LVM_Test' ... Remove the change, install it locally, restart libvirt ... # service libvirtd restart Restarting libvirtd (via systemctl): [ OK ] # virsh pool-list Name State Autostart ------------------------------------------- default active no images active yes LVM_Test active yes test_nfs_pool active no So the question becomes can we make 'auto' be a synonym for 'unknown' - that is accept both in some way.
