This patch ensures that\nthe UUID remains valid by duplicating it into a newly allocated\nmemory space. The value is then inserted into the hash table\nwith this persistent UUID key to ensure that the key stored in\nthe hash table remains valid as long as the hash table entry\nexists.\n\nFixes: faefdba847 (\"hw/display: introduce virtio-dmabuf\")\nSigned-off-by: Dorinda Bassey <dbassey@redhat.com>\nReviewed-by: Stefano Garzarella <sgarzare@redhat.com>\nReviewed-by: Albert Esteve <aesteve@redhat.com>\nReviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com>\nReviewed-by: Jim MacArthur <jim.macarthur@linaro.org>\nReviewed-by: Michael S.
