Re: [Xen-users] max utilization

[Jonathan Ludlam <Jonathan.Ludlam@xxxxxxxxxxxxx>]

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.
