What's *running* in the guests? In a prior life, I was in the VM and Linux team supporting apps mostly WAS based. We saw a lot of "mysterious" loads. While IBM has made improvements in WAS, the apps are always in need of review.
The most common (and extreme) example is apps which poll. Not so much a concern on an otherwise idle PC, this is a gross CPU waste in any shared environment, virtual or not. Look for things like that. But that's just one example. -- R; <>< On Jan 10, 2014 11:04 AM, "Victor Echavarry Diaz" <vechava...@evertecinc.com> wrote: > From a couple of days one of our Linux LPAR are continuously using 100% of > two cpu.
