[Xen-users] How many VMs on single server...

["Alessandro R." <lord2y@xxxxxxxxx>]

Hi List,

is there mathematical method to calculate how many VMs I can run on a
single server?
For example: in my setting I have one server with Intel Xeon 3050 Dual
Core - single socket - with 4GB Ram and 2 hdd of 250GB SATA; hard
drive is mirroring with software RAID and I'm using an image disk for
xen VM. I want run only HVM vm.

How many VMs can I run on this?

Now I'm using RAM as delta (suppose to give 5-10 GB of disk space):
if I give for each VM 256MB of RAM I will be able to start 14 domU
with 90 - 100 MB of RAM in dom0.

Is it right?

Does anyone know another more accurate method?

Thanks.

Kind Regards.
