Increase Memory of Nutanix CVM

Insufficient memory & CVM is crawling require more memory...

In this post, we will look at how to increase CVM memory.

Before that, turn off the entire virtual machine before shutdown CVM.

[Get CVM name]
virsh list








[Get CVM properties]
virsh dominfo <CVMName>

[Shutdown CVM]
virsh shutdown <CVM Name>

[Change memory]

virsh setmaxmem <CVM Name> 12GB --config
virsh setmem <CVM name> 12 GB --config

[Start CVM]
virsh start <CVM Name>

That should do the trick!
