Hello, cpu.overprovisioning.factor is a multiplier on your actual CPU capacity. Say you have 4 physical cores at 2 GHz each, you have a total capacity of 8 GHz. An overprovisioning factor of 2 will make cloudstack to count as if there were 16 GHz and allocate up to that.
cluster.cpu.allocated.capacity.disablethreshold is the maximum capacity you want to allocate. Based on the above example, you can set it to stop allocating vms once you've reach 90% capacity (over overprovisioned cpu, this is th 16 GHz). thx On Mon, Nov 26, 2012 at 7:01 PM, Donal Lafferty <donal.laffe...@citrix.com>wrote: > I was thinking of > > cpu.overprovisioning.factor > > and > > cluster.cpu.allocated.capacity.disablethreshold > > > DL > > -----Original Message----- > From: Nitin Mehta [mailto:nitin.me...@citrix.com] > Sent: 26 November 2012 5:03 PM > To: cloudstack-users@incubator.apache.org > Subject: Re: Create instance > > > > On 26-Nov-2012, at 3:34 PM, Donal Lafferty wrote: > > > One thing to watch out for is that CloudStack caps the CPU and RAM > allocated for a host.
