Hello,

we have some dom0 running on 8 core Intel XeonCPU E5345 2.33GHz with 8GB Ram,
right now we have only 1GB to 2GB free on each dom0 and mostly only 3VM running.
Would it be possible for us to go to 16GB and add another 3-4 VM, or
go to 32GB and run up to 12VM on one machine?
Im not sure we activily use the VM Support that these CPU/Server come
with, how can I find more info about this out of xen?

Just thinking about what will be possible on our current hardware. Im
doing some RTG with cacti from our dom0 and the domU,
but the dom0 doesnt draw the network/cpu usage that the domUÂs use,
are there more ways to get  performance/usage infos?


greets
