How can I display a different memory and CPU/core configuration than the actual values for a VM?

I have created a VM with 4GB of memory, 50GB of storage, and 2 CPUs, but I want to show it on VM with 8GB of memory and 4 CPU cores. How can I achieve this?

That won't work well. If you tell the VM it has 8 GB of memory, but actually only provide it with 4 GB it will likely crash or panic every time it's trying to use anything more than the 4 GB it actually has available.

Hello @sterzy, than you for quick response.

I will handle those things like panic or utilization of memory, I just need to apply this on the VM. I would like to know if it is possible with Proxmox, and if so, please provide the relevant documentation

You could choose 4 vCPUs in the VM hardware setting and config a CPU-limit of 2. So it can only use 2 real CPU cores.
No idea about to do this for RAM.

Okay, is there any docs for it?

Of course. This topic is explained here: https://pve.proxmox.com/pve-docs/chapter-qm.html#qm_cpu

Great, I now want to create storage for Proxmox using NAS/SAN. Which method would be faster and more cost-effective? I need to be able to add disks to the SAN/NAS as needed without any downtime. Additionally, if any node in the cluster goes down, I want the storage to remain separate so the VMs can migrate to another node easily. Could you please provide a better suggestion on how I should approach this?
