Que plataforma do Ubuntu Server devo escolher com i686 cpu? [fechadas]

0

Eu trago de volta à vida uma máquina desktop bastante antiga (como eu acho) que era usada como servidor. No processo de revisão de hardware e software e tropeçar em um fato eu não sei qual versão do Ubuntu Server optar por atualizá-lo. No começo eu sinto que deve ser Ubuntu 16.04.2 LTS (32 bits), mas as coisas começam a brincar com a minha mente em breve.

Bits importantes (na minha opinião)

  1. A arquitetura da CPU é i686
  2. O modo operacional da CPU pode ser de 64 bits
  3. LM sinalizador presente
  4. width é 64 bits
  5. Sinalizador de VMX ausente - extensões de máquina virtual não são suportadas
  6. Versão em execução do LTS Ubuntu Server (desatualizado em breve)
  7. Execução na plataforma i686
  8. o getconf LONG_BIT está gerando 32

O 1-4 é uma boa indicação dos recursos do sistema x64, mas o ponto 5 está me dizendo o que eu não posso virtualizar sistemas guest x64 ( link ), e o ponto 8 está me dizendo que é o sistema operacional de 32 bits aqui.

Então qual servidor Ubuntu devo escolher para uma atualização? Minha máquina é capaz de executar o sistema operacional de 64 bits? Ou devo ficar com 32 bits?

Para as diferenças entre i686 e x86_64 podem ser lidas nesta página;

Eu acho que você definitivamente entende por que você deve usar 32 bits.

O seu deve definitivamente usar 32 bits, ou seja, versões i386 do software aplicativo e do sistema operacional. O i686 não é um computador de 64 bits explícito. é uma versão posterior do i386, ou seja, computadores Intel 8, 16 e 32 bits
