In certain conditions and/or libvirt versions, the hot plug of disks won't work unless the disk belongs to the default pool.

It does not make sense for me. I should be able to hot plug any disk in any pool unless we have a libvirt/qemu issue there. > This patch fixes github bug #507: > > https://github.com/kimchi-project/kimchi/issues/507 > > Signed-off-by: Daniel Henrique Barboza <dhbarboza82(a)gmail.com&gt; > --- > tests/test_model.py | 24 ++---------------------- > 1 file changed, 2 insertions(+), 22 deletions(-) > > diff --git a/tests/test_model.py b/tests/test_model.py > index c956007..c27e138 100644 > --- a/tests/test_model.py > +++ b/tests/test_model.py > @@ -329,9 +329,6 @@ class ModelTests(unittest.TestCase): > > @unittest.skipUnless(utils.running_as_root(), 'Must be run as > root') > def test_vm_disk(self): > - disk_path = '/tmp/existent2.iso' > - open(disk_path, 'w').close() > - > def _attach_disk(expect_bus='virtio'): > disk_args = {"type": "disk", > "pool": pool, > @@ -343,30 +340,13 @@ class ModelTests(unittest.TestCase): > # Check the bus type to be 'virtio' > disk_info = inst.vmstorage_lookup(vm_name, disk) > self.assertEquals(u'disk', disk_info['type']) > - self.assertEquals(vol_path, disk_info['path']) > self.assertEquals(expect_bus, disk_info['bus']) > return disk > > inst = model.Model(objstore_loc=self.tmp_store) > with RollbackContext() as rollback: > - path = os.path.join(os.getcwd(), 'kimchi-images') > - pool = 'test-pool' > vol = 'test-volume.img' > - vol_path = "%s/%s" % (path, vol) > - if not os.path.exists(path): > - os.mkdir(path) > - rollback.prependDefer(shutil.rmtree, path) > - > - args = {'name': pool, > - 'path': path, > - 'type': 'dir'} > - inst.storagepools_create(args) > - rollback.prependDefer(inst.storagepool_delete, pool) > - > - # Activate the pool before adding any volume > - inst.storagepool_activate(pool) > - rollback.prependDefer(inst.storagepool_deactivate, pool) > - > + pool = 'default' > params = {'name': vol, > 'capacity': 1073741824, # 1 GiB > 'allocation': 536870912, # 512 MiB > @@ -409,7 +389,7 @@ class ModelTests(unittest.TestCase): > disk_args = {"type": "disk", > "pool": pool, > "vol": vol, > - "path": disk_path} > + "path": '/disk/path.img'} > self.assertRaises( > InvalidParameter, inst.vmstorages_create, vm_name, > disk_args) >

I haven't found any working example in Suse or Red Hat docs in which the hot plug works without putting the image in /var/lib/libvirt/images dir. Besides, isn't that exactly what Kimchi does? Or does Kimchi allows hot plug a disk from any pool in any dir?
