First instance is cpu.time not incrementing even with the VMs on the hypervisor running a stress tool. After running 'virsh domstats' sometimes it'll go into a state where no output is generated at all. Have anyone seen something like this? We're running a pretty recent build of libvirt. </div><div id="yui_3_16_0_ym19_1_1541699803753_188123" dir="ltr"><br></div><div id="yui_3_16_0_ym19_1_1541699803753_188123" dir="ltr"># virsh version</div><div id="yui_3_16_0_ym19_1_1541699803753_188123" dir="ltr">Compiled against library: libvirt 3.9.0</div><div id="yui_3_16_0_ym19_1_1541699803753_188123" dir="ltr">Using library: libvirt 3.9.0</div><div id="yui_3_16_0_ym19_1_1541699803753_188123" dir="ltr">Using API: QEMU 3.9.0</div><div id="yui_3_16_0_ym19_1_1541699803753_188123" dir="ltr">RUNNING HYPERVISOR: QEMU 2.9.0</div><div id="yui_3_16_0_ym19_1_1541699803753_188123" dir="ltr"><br></div><div id="yui_3_16_0_ym19_1_1541699803753_188123" dir="ltr">Through the two domstats we see that the cpu.time is not increasing, but vcpu.0.time is not.
