I wants to know when & how the esx host manage teh meory
Esx host have 98 GB RAM and hosted 10 VM ( each VM have 24GB RAM)
I can see the Host Mem utilisation is 92GB. (Shared by all VM and directly consuming from Physical RAM)
At VM level, there is no value for Ballooning & swaping.
1 I wants to know why the Ballooning and swapping is not happening ?
2 If VM are occupied more than 90 % in Physical memory, whether i can build anotehr VM with Large memory in the same host ?
3 At above said condition(92 Gb utilised), if all VM are requesting for their granted memory, then how the esx host will manage ( This situation, ESX already triggered Critical Mem usage Alarm)
If all machines request their memory, the ESX host will start to swap to disk, causing performance issues.
