Subject: [PATCH] qemu_migration_params: Refactor qemuMigrationParamsApply
|
|
|
|
qemuMigrationParamsApply restricts when capabilities can be set, but
|
|
this is not useful in all cases. Let's create new helpers for setting
|
|
migration capabilities and parameters which can be reused in more places
|
|
without the restriction.
