Is there a way to limit cpu usage for a KVM guest? In other words, if I am running four guest servers and something on one of them begins to use a ton of cpu, I don't really want it to slow down all the others. Is the only way to do this by limiting it to one cpu core? Granted, I would prefer that it have access to full computing power if no other guest needs it. Thanks for any advice. Steve Lorimer
