Esxi problem periodically cpu load at vm up to 100%

Esxi problem periodically cpu load at vm up to 100% 4 core cpu 3 up to vm

need  any advices

[Sreejesh_D]

welcome to the communities!!

pls provide the following details.

1. is it the only VM has issue on the host?

2. If yes, check the processes running in the VM and see which process consume more CPU.

3. If there are more VMs have the issues then we have to do detailed performance analysis using esxtop.

There are running two VM one not requred much resurces but situation is same host freq drop down

it's shows that it's always run at below 100% cpu load but VM's show almost load about 20-60% ... maybe it overheating i cant monitore cpu temps AMD Athlon II x4 3GHZ

drops continues ....

all services very laggey ...

info from one of two virtual machine

same time at graphs load about 100% by sphere info ...

is any way to get temp info from Athlon II cpu ?

[cyclooctane]

Getting temp info from an athlon CPU would depend on the chip set and the ESXI drivers.

I do not know how easy it would be.

esxtop should be able to tell you something.

It will give you a process list of what is using CPU on the host.

Also, what are the power saving settings in the BIOS.

This is because these can down clock the CPU under some workloads, however this downclock is not reported to the guest OS.

ok i will check ... i have disabled several services and will check how it will work ...

is there any way to set lowest limit of VM's freq high limit can be set but lowest I can't find how ... that vm respond critical.

[cyclooctane]

You can try setting the critical VMs CPU reservations.

I do not know of any other solution, other then to look at the VMs and see if they are doing anything that is highly prosessor intensive at the time.

I have had this problem on a MSSQL server for a client, and preforming database maintance fixed it, so we did not look into it further.

I've already set reservation but when system not intensively loaded virtual freq goes down and when it demand high respond first time it's not quite good
