Re: [libvirt] [PATCH] bhyve: implement domainGetCPUStats

For per CPU stats, implement virBhyveGetDomainPercpuStats() that uses bhyvectl tool to obtain the guest's vcpu stats. For total CPU stats, add virBhyveGetDomainTotalCpuStats() that gets the hypervisor process CPU stats using kvm (kernel memory interface). --- configure.ac | 7 +++ src/bhyve/bhyve_driver.c | 38 +++++++++++++ src/bhyve/bhyve_process.c | 136 ++++++++++++++++++++++++++++++++++++++++++++++ src/bhyve/bhyve_process.h | 10 ++++ 4 files changed, 191 insertions(+) diff --git a/src/bhyve/bhyve_process.c b/src/bhyve/bhyve_process.c index a557bc5..e1f4324 100644 --- a/src/bhyve/bhyve_process.c +++ b/src/bhyve/bhyve_process.c
