Via boot parameter sched-gran=core (or sched-gran=socket) it is possible to change the scheduling granularity from cpu (the default) to either whole cores or even sockets. All logical cpus (threads) of the core or socket are always scheduled together. This means that on a core always vcpus of the same domain will be active, and those vcpus will always be scheduled at the same time. This is achieved by switching the scheduler to no longer see vcpus as the primary object to schedule, but "schedule items". Each schedule item consists of as many vcpus as each core has threads on the current system. The vcpu->item relation is fixed. I have done some very basic performance testing: on a 4 cpu system (2 cores with 2 threads each) I did a "make -j 4" for building the Xen hypervisor. With This test has been run on dom0, once with no other guest active and once with another guest with 4 vcpus running the same test. The results are (always elapsed time, system time, user time): sched-gran=cpu, no other guest: 116.10 177.65 207.84 sched-gran=core, no other guest: 114.04 175.47 207.45 sched-gran=cpu, other guest: 202.30 334.21 384.63 sched-gran=core, other guest: 207.24 293.04 371.37 All tests have been performed with credit2, the other schedulers are untested up to now. Cpupools are not yet working, as moving cpus between cpupools needs more work (this is the reason for the series still being RFC). Same applies to cpu add/remove.
