Hi,

On running on a dual/quad core does the Xen scheduler take into account the physical layout of the cores.

For example if a VM has two vcpus, and there are 4 physical cpus free, will it take care to assign the 2vcpus (from a VM) to 2 pcpus on the same socket.

Shouldn't this is be concealed.You may never know which physical CPU is actualyl running a vcpu. It may get scheduled on to a different physical CPU depending on the load on the other CPUs.
