Hi all: I'm testing with a AIO node(iso version:20190607T142331Z). To meet increasing vcpu requirments, I turn on hyper-threading(ht) in BIOS configuration. Now the cpu num of system have been twice as much as before(12), but the num of vcpu did not changed(still 4). Relating to problem: 1. The num of cpu is correct in libvirtd container, check it with 'kube exec -it pod_id lscpu' 2. Checking cpu with `system host-cpu-list` ,and seems it had allocated new added cpu to applications and platform separately correct.
