Re: [Xen-users] RAM issue

Quoting Arpan Jindal <jindalarpan@xxxxxxxxx>:

no i dont need it at all..
what is the minimum survive with i need to run 20 vm under it ....
and how i can decrease it


In your /boot/grub/menu.lst file of your dom0, you will see a line similar to the one below, notice how I have told dom0 it is only going to get 512M of RAM. I am not sure if you could just say 512M after the '=' sign, this is how I have always done it. To get this number you would multiply whatever RAM value by 1024.

I am not sure what a good value for dom0 would be. I use 512MB because I have installed a minimal OS using just what I need for a base system and just what I need for Xen. I am not sure how fat distros like CentOS or Fedora or the debian type systems are. Do they install a desktop environment for dom0? I don't know.

e.g.

256MB     256*1024=262144
512MB     512*1024=524288
9GB       9216*1024=9437184  ;)

kernel /boot/xen-3.2gz dom0_mem=524288
