    kvm steal time handling


    Hi

    I am currenlty having :
    At the host : kernel 3.2.0-20-generic (original)
    At the guest kernel 3.0.0-17-virtual (original)

    With this combination steal time option was not active

    In .config I set CONFIG_PARAVIRT_GUEST=y,CONFIG_PARAVIRT_TIME_ACCOU NTING=y
    to enable steal time handling when the kernel is rebuild

    Questions:
    -Is it enough to use the newly build kernel as the host kernel (hypervisor) or also necessary to use it at all the guests of that hosts
    -Does monitoring of steal time degrade guest performance a lot ?

    thanks
