Subject: [PATCH] virStoragePRDefFormat: Suppress path formatting for

If there are managed reservations for a disk source, the path to
|
|
|
9c6c51 |
the pr-helper socket is generated automatically by libvirt when
|
|
|
9c6c51 |
needed and points somewhere under priv->libDir. Therefore it is
|
|
|
9c6c51 |
very unlikely that the path will work even on migration
|
|
|
9c6c51 |
destination (the libDir is derived from domain short name and its
|
|
|
9c6c51 |
ID).
