[Xen-users] How can i be able to determine if a host its overloaded?
Hello, i have run in a little problem with my host, and i have two questions perhaps someone can help me with, they are: It is possible to determinate if a host has ran out of "space" as in , reach the machine limit for virtual machines? Is there some rule of thump or command to see the work load of the dom0? Right now my dom0 its a machine with a 2 GHz dual core intel VT able processor, 4 Gig RAM and 2 gig-e network cards, how can i know how many machines (for example with 256 Mb RAM, 1 virtual processor) can it run? Thanks, Miguel _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

If they are all idle, no problem, if the all stress your cpus - problem. But i dont know how to meassure the load of dom0.
