Cum activezi Memory Ballooning pentru mașini virtuale în Proxmox VE

Într-un mediu virtualizat Proxmox VE, este posibil ca mai multe mașini virtuale să rezerve memorie RAM pe care nu o folosesc în mod constant.

Acest lucru poate duce la:

  • utilizare ineficientă a memoriei serverului

  • imposibilitatea pornirii unor VM-uri noi

  • performanță scăzută când resursele sunt limitate

Proxmox oferă o funcționalitate numită Memory Ballooning, care permite redistribuirea dinamică a memoriei între mașinile virtuale în funcție de necesități.
