Re: [Xen-users] max utilization
actly my scenario is i am testing network driver for our 10G NIC card. for that i have inserted our 10G card in xenserver machine & installed our driver in order to test that need to send heavy traffic from physical host (xenserver) to peer(linux machine). in that case if i send heavy traffic host is getting hang. for that purpose i want to giv more memory & cpu to dom0 .
thanks balakrishna. On Tue, Oct 19, 2010 at 6:01 PM, Jonathan Ludlam <Jonathan.Ludlam@xxxxxxxxxxxxx> wrote:
I don't think you want to do that.
dom0 is intended to be lightweight so as to leave as many resources as possible for your VMs. For example, your VMs will are only able to use what's left of your memory, so we try hard to keep dom0's memory usage to a minimum.
In your case, dom0 is taking about 550 megs, leaving your VMs about 15.5 gigs to use.
