[GitHub] [cloudstack] leolleeooleo opened a new issue #5497: CPU frequency detection not maxmum on Rocky 8
leolleeooleo opened a new issue #5497:
URL: https://github.com/apache/cloudstack/issues/5497
##### ISSUE TYPE
* Improvement Request
##### COMPONENT NAME
~~~
agent
~~~
##### CLOUDSTACK VERSION
~~~
4.15.2.0
~~~
##### CONFIGURATION
N/A
##### OS / ENVIRONMENT
CentOS 8/Rocky 8
##### SUMMARY
CPU capability detection error.
Because cloudstack-agent detected CPU is running at low frequency,
Not the CPU Maxmum frequency.
When start VM will show "Cannot deploy the VM to specified host 21; host has cpu capability? false, host has capacity? true"
While I override value in database, it works fine.
But restart cloudstack-agent will be override by new detect low frequency.
~~~
$mysql
update host set speed = 2660 where id = 21;
~~~
##### STEPS TO REPRODUCE
~~~
$ cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 44
model name : Intel(R) Xeon(R) CPU E5640 @ 2.67GHz

address sizes : 40 bits physical, 48 bits virtual
power management:
~~~
##### EXPECTED RESULTS
~~~
cpu frequency * core * cpu.overprovisioning.factor = CPU Total
2.66 GHz * 16 * 32 = 3661.92 GHz
~~~
##### ACTUAL RESULTS
~~~
cpu frequency * core * cpu.overprovisioning.factor = CPU Total
1595.704 MHz * 16 * 32 = 817 GHz

Maybe I found the problem is.
Dell Server BIOS has Power Management Profile setting.
It is set to Active Power Controller (Dell designed, BIOS controlled processor frequency scaling).
I'll try to set it to OS Control (Operating system controlled processor frequency scaling).

When it is unable to find the `cpuinfo_max_freq` file, it falls back on the data reported by libvirt.
It looks like a non cloudstack issue since it only faces the problem on specific hardware and OS
As a workaround we can look into a different way of fetching the max cpu in the agent

[GitHub] [cloudstack] leolleeooleo commented on issue #5497: CPU frequency detection not maxmum on Rocky 8
Posted by GitBox <gi...@apache.org>.
leolleeooleo commented on issue #5497:
URL: https://github.com/apache/cloudstack/issues/5497#issuecomment-925616061
The file /proc/cpuinfo in CentOS 7 was Max frequency,
CentOS 8 and Rocky 8 are not always Max frequency, depend on idle or busy.
I get the log from here
https://github.com/apache/cloudstack/blob/4.15.2.0/plugins/hypervisors/kvm/src/main/java/org/apache/cloudstack/utils/linux/KVMHostInfo.java#L85
~~~
tail -f /var/log/cloudstack/agent/agent.log
2021-09-23 16:17:43,954 INFO [utils.linux.KVMHostInfo] (Agent-Handler-1:null) (logid:) Could not read cpuinfo_max_freq, falling back on libvirt
~~~
And I had try (CentOS 7, CentOS 8, Rocky 8 are same)
and this only on Dell PowerEdge R410 and R610, others hardware are fine.

This could be OS related, in the env I've tested, the CPU Mhz matches the CPU Max frequency
