Re: [Xen-users] GRUB boot parameters: dom0_mem

[Randy Katz <rkatz@xxxxxxxxxxxxxxxxxxxxx>]

Hi,

from my grub.conf file:

module /vmlinuz-2.6.18-274.7.1.el5xen ro root=LABEL=/ nodmraid dom0_mem=512M pci=nomsi

I have heard talk of 256M but have not tried it yet.

Regards,
Randy

I've installed Xen Hypervisor 3.0.3 (CentOS 5.7, i386) inside Virtualbox 4.1.16 (Mageia 1, i686) and have noticed that Dom0 is consuming 85% of the memory allocated to the VM (1GB) so I'd like to reduce this as much as possible in order to make more room for one or two VM's.

Is there a minimum amount of vRAM that can/should be allocated to Dom0 (using the dom0_mem boot parameter) considering that I only want to host one or two VM's?
