For per CPU stats, implement virBhyveGetDomainPercpuStats() that uses bhyvectl tool to obtain the guest's vcpu stats.
In virDomainGetCPUStats API, the start_cpu and ncpus parameters refer to host CPUs, not the vcpus.
Looks like I misunderstood the API. :-(
In other words, this API operates with the host CPUs? So if user calls it with e.g. start_cpu = 2 and ncpus = 2, I should return info on how much time host CPUs 2 and 3 spend on the given domain (as the opposite to how much time domain's vcpu 2 and vcpu 3 were busy)?
Yes.

Looks like FreeBSD does not support such kind of per-cpu reporting for host cpus. Just to make sure I didn't miss something, I asked that question of the FreeBSD virtualization maillist and looks like I'm right about that [1]. Would it better to abandon this feature for now and wait when it'd be supported (I'm not sure if/when it's going to happen), or just leave the code that reports only the stats for all cpus? 1: http://lists.freebsd.org/pipermail/freebsd-virtualization/2014-April/002477....
