vm's are getting deployed exceeding cpu allocation in ACS 4.20.2.0

[gvaishya]

problem

We are experiencing an issue with the cpu overprovisioning factor in ACS. Although the parameter cpu.overprovisioning.factor is set to 1, VMs are still being deployed on hosts even after reaching full CPU allocation. This is resulting in allocation exceeding 100%.

Refer the attached snippet

CPU: 2 processors, Intel(R) Xeon(R) Gold 6148 CPU (2.40 GHz / 20-core). Hyperthreading is enabled. (80 * 2.4 = 192 GHZ )
Memory: 768 GB

cpu.overprovisioning.factor is set to 1 globally and at cluster level.

versions

ACS Version: 4.20.2.0
DB : Maria DB 10.3.39
ACS and KVM host : RHEL 8

What to do about it?

We are using mixed hardware in sinlge cluster and vm.allocation.algorithm global setting set to "firstfitleastconsumed"

cpu.overprovisioning.factor = 1

Below are the HW types
2 processors, Intel(R) Xeon(R) Gold 6154 CPU (3.00 GHz / 18-core)
2 processors, Intel(R) Xeon(R) Gold 6254 CPU (3.10 GHz / 18-core)
2 processors, Intel(R) Xeon(R) Gold 6148 CPU (2.40 GHz / 20-core)

We are using mixed hardware in sinlge cluster

try avoiding this. also try to only have one os(type/version) per cluster. It will save you a lot of trouble shooting.

we are using same OS and HW is also same but only difference is CPU cycle. Any suggestions why cpu allocation is exceeding 100% though overprovisioning is set to 1 and cluster.cpu.allocated.capacity.disablethreshold is also 100%

can you share the result of mysql query

select * from op_host_capacity where capacity_type =1;
