You're describing kqemu, not qemu. Qemu is an emulator; it can emualte a large number of guests on a large number of hosts, albeit at fairly slow speeds. kqemu is a "qemu accelerator" which can be used to speed up qemu emulation if the guest and host are the same. kvm is a hardware virtualization system that is part of the Linux kernel. While at present the only serious user is a modified qemu, it is not tied to qemu. It is faster than either qemu of kqemu. The downside is that it requires hardware virtualization extensions for fully virtualized guests. -- error compiling committee.c: too many arguments to function ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
