Manifesto de importação da VM
O manifesto de importação é um arquivo XML criado e consumido pelas operações ImportInstancede API do Amazon EC2 e. ImportVolume Observe que essas operações não são suportadas pelo AWS CLI.
O manifesto permite que a imagem de uma máquina virtual seja dividida em pequenas partes para transferência e depois remontada no destino, com suporte para repetir transferências parciais malsucedidas. Esse arquivo geralmente é criado, consumido e destruído pelas ferramentas do Amazon EC2 sem a intervenção do usuário.
Em algumas situações excepcionais, os desenvolvedores podem querer construir um manifesto manual ou programaticamente, possibilitando ignorar determinadas operações da API e, ao mesmo tempo, fornecer um manifesto para outras operações que exigem o arquivo como valor de parâmetro.
Este tópico documenta a estrutura do manifesto e fornece um arquivo de amostra.
nota
A manipulação direta do manifesto se afasta do fluxo de trabalho padrão da API do Amazon EC2. Em vez disso, recomendamos que você siga os procedimentos nos Import/Export processos de VM.
Esquema do manifesto
O esquema abaixo descreve o formato do manifesto. A documentação dos elementos do esquema é apresentada em linha.

Exemplos
Esse primeiro exemplo de manifesto descreve uma imagem de volume com duas partes. Os arquivos contendo as peças estão em um sistema local e devem ser enviados para o Amazon S3.
