Just did a quick test on my main KVM host, a 8 core Intel(R) Xeon(R) CPU E3-1240 V2. KVM guests are 4.10 w/o CONFIG_KAISER and kvmconfig without CONFIG_PARAVIRT. Building a defconfig kernel within that guests is about 10% slower when CONFIG_KAISER is enabled. Is this expected? If it helps I can redo the same test also on bare metal. -- Thanks, //richard
