I will just disable its compilation by default, but the code will still be there for some time, so you will be able to enable it with the --target-list option.
This target is replaced by the standard QEMU with soft mmu support. The QEMU Kernel Acceleration Layer which will be unveiled very soon will give much more performance while working with unpatched guest OSes.any numbers for that? will it be compareable?
All I can say is that for Linux or Windows user code (such as nbench), the performance is the same as the native one.
what will it require?
A small host kernel module is needed. It works with 2.4 and 2.6 Linux kernels.
