Running the client as a vm and yet more on individual workloads failing posted: Aug 27, 2009 3:26 PM

I am currently in a situation where I don't really have a physical client to use for testing my setup. I have one ESX server with a test tile deployed and on VM setup to the client spec. The ESX host is an 8 core 32GB blade.

I am experiencing similar problems to some of the other folk that have posted on here where I can run each workload individually but it seems like when I try to run all of them one or more will fail. No matter what I seem to do with the startup timing something always bombs out. Initially it was usually the fileserver workload. I moved things about then the java workload was giving me an error saying that it did not run/complete ran for some amount of time but the expected time was whatever duration I had set. I am assuming that job may never have actually started and that was just how long it took to timeout.

I just set this all up this week and I am using the 3.3.4 version of staff, unmodified linux vm's downloaded from the vmware site, and all the latest versions of the other free products that were required, and finally specweb2005 and specjbb2005.

Is having the client run as a vm on the same host causing my problems? It seems like one tile should run just fine with the client as a VM. It may not be a certified spec config for reporting results but I would think it should work for my configuration testing.

Some of the things I would try would be to check to see if all VMs are using all 8 cores. If they are, try assigning some VMs to only use specific cores and others VMs the remaining ones.

Also if you don't have resource pools setup, try that as well with hard defined resource requirements. That way if a machine starts to misbehave, it will be limited to what the resource pool has available, not what the entire box has.

Beyond that, are all VMs using the same NICs etc?

If you try all this out, while things are running check the performance at all 3 levels. (box, resource pool, individual VM). That should help isolate where the problem lies. At the very least you'll have a better idea of what kind of resources your devices are needing and what you can do to correct the situation.

While not super technical answer, hopefully this does point you in an unexplored direction.
