In `virtio_add_resource` function, the UUID used as a key for `g_hash_table_insert` was temporary, which could lead to invalid lookups when accessed later. This patch ensures that the UUID remains valid by duplicating it into a newly allocated memory space (persistent_uuid). The value is then inserted into the hash table with this persistent UUID key to ensure that the key stored in the hash table remains valid as long as the hash table entry exists.
