[libvirt PATCH 2/4] qemu_migration_params: Replace qemuMigrationParamTypes array

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We will need to annotate individual parameters a bit more than just
noting their type. Let's introduce qemuMigrationParamInfo replacing
simple qemuMigrationParamTypes with an array of structs.
