Guest running slow with 100% CPU load

[steveculshaw]

We've got a guest server which no matter what we've tried is going to 100% CPU

- originally thought it was Index Services, disabled it, then it seemed to be the anti-virus (Trend), disabled it ... and so on

- we even copied the machine over to our test/dev Virtual Server and it's running like a dog there as well

Has anyone got any pointers on where to look / what to check, as we are bashing our collective heads against a brick wall ?

So is it the VM that reports 100% CPU or ESX? Also is this VM a P2V?

[steveculshaw]

Dave, it's the guest that goes 100% CPU, ESX only seems to reckon it's barely ticking over

It was a clone of a virtual base image, not a P2V

In task manager what processes are taking the CPU time?

[steveculshaw]

That's what has us so baffled, originally it was the Indexing Search service, so I disabled it

Then Trend (the antivirus) started going like the clappers

Seems like everytime we stop one thing, another decides to go 100%

How many vCPU are in your system? In your clone, did you have the same number of vCPU, if not, how many?

[steveculshaw]

It's a quad core, dual processor server, the guest is set to two CPU

try with a single CPU. We hade the same Problem. After chaging to 1 CPU i get better performance and low cpu usage. Sometimes is less more.

Kind regards

Nope, not spotted that ... thanks for the pointer. This looks very relevant as our ESX is a 2 machine cluster with VMotion

Cheers,
