Kleines Script zwischendurch: Über dieses Perl-Konstrukt kann man auf einem vSphere Management Assistant eine vMotion auf der Konsole auslösen. So lassen sich recht einfach eventgesteuerte vMotion-Aktionen umsetzen. Ich nutze es z.B. um zeitgesteuert VMs an Standorte mit höherer erwarteter Hitrate zu verlegen oder bei Störungen kritische VMs automatisiert auf „sicherere“ Hosts zu migrieren. Das Original stammt von William Lam, ich habe einige Punkte etwas umgebaut um Storage-vMotion auszuklammern. Üblicher Disclaimer: Proof of concept, keine Garantie, nicht-Programmierer-versucht-sich-an Perl, Works for me.
