Re: [libvirt] [PATCH] bhyve: report cpuTime in bhyveDomainGetInfo

Add a helper function virBhyveGetDomainTotalCpuStats() to obtain process CPU time using kvm (kernel memory interface) and use it to set cpuTime field of the virDomainInfo struct in bhyveDomainGetInfo(). --- configure.ac | 7 +++++++ src/bhyve/bhyve_driver.c | 9 +++++++++ src/bhyve/bhyve_process.c | 40 ++++++++++++++++++++++++++++++++++++++++ src/bhyve/bhyve_process.h | 3 +++ 4 files changed, 59 insertions(+)
