This patch provides hypercalls for the i386 port I/O instructions,Won't these workloads be better off using paravirtualized drivers? i.e., do the native drivers with paravirt I/O instructions get anywhere
which vastly helps guests which use native-style drivers. For certain
VMI workloads, this provides a performance boost of up to 30%. We
expect KVM and lguest to be able to achieve similar gains on I/O
intensive workloads.
near the performance of paravirt drivers?
drivers/lguest/core.c, which is a real relief.
Hrm... how do you deal with X doing IOs ?
