Ich erwecke eine ziemlich alte Desktop-Maschine zum Leben (wie ich denke), die als Server verwendet wurde. Während der Überarbeitung von Hardware und Software weiß ich nicht, welche Version von Ubuntu Server sie aktualisiert. Zuerst habe ich das Gefühl, dass es Ubuntu 16.04.2 LTS (32-Bit) sein muss, aber die Dinge beginnen sehr bald mit meinem Verstand zu spielen.

Wichtige Punkte (meiner Meinung nach)
- CPU-Architektur ist i686
- Der CPU-Betriebsmodus kann 64-Bit sein
- LM Flagge vorhanden
- Die Breite beträgt 64 Bit
- VMX-Flag fehlt - Erweiterungen der virtuellen Maschine werden nicht unterstützt
- Laufende Version von LTS Ubuntu Server (bald veraltet)
- Läuft auf der i686- Plattform
- getconf LONG_BIT gibt 32 aus
1 bis 4 sind ein guter Hinweis auf die x64-Systemfähigkeiten, aber Punkt 5 sagt mir, was ich nicht mit x64-Gastsystemen virtualisieren kann ( https://en.wikipedia.org/wiki/X86_virtualization ), und Punkt 8 sagt es mir ist 32-Bit-Betriebssystem hier unten.
Welchen Ubuntu-Server soll ich für ein Update auswählen? Kann mein Computer ein 64-Bit-Betriebssystem ausführen? Oder soll ich bei 32 bit bleiben?
Antworten:
Informationen zu den Unterschieden zwischen i686 und x86_64 finden Sie auf dieser Seite.
https://www.redhat.com/archives/rhl-list/2006-October/msg03684.html
Ich denke, Sie verstehen auf jeden Fall, warum Sie 32-Bit verwenden müssen.

Sie sollten auf jeden Fall 32-Bit- bzw. i386-Versionen der Anwendungssoftware und des Betriebssystems verwenden. Der i686 ist kein expliziter 64-Bit-Computer. Es ist eine spätere Version des i386, dh Intel 8, 16 und 32-Bit-Computer
