How much RAM does Proxmox need ?

[XZed]

Hello,

I followed the minimal recommendations given by proxmox (1 Gb RAM) and allocated 512 Mo RAM for a linux guest.

But i was wondering how much minimal ram does proxmox need, in order to allocate the maximum ram to the guest.

256 Mo ?

Thank you,

Sincerely,

The rule of thumb is, more RAM the better. You could run guests with 128MB RAM, but you will start to swap to disk fairly quickly if the VM is busy.

A proxmox server with 1GB RAM is going to be very limited in the number of guests it can support, especially if your using KVM rather then OpenVZ.

Hello,

Thank you for your advices. But you can be relieved, my actual configuration is setup for testing purposes :

* I wanted to validate the good functionment of Proxmox on simple Dell PowerEdge T100

* For my first experiments, i'm actually validating benefits brought by virtualization for VM (easy backup, etc...).

Thank you.
