It is true that it is too slow for "real" work that is cpu-bound, if the kqemu acelerator module is not used. But if you just want to test if an ISO image is bootable, then qemu is fast enough. In fact, booting a FreeBSD CD up till the Login prompt is faster in qemu than on real hardware. > xen is rather good, but not on dfly. So far, qemu has worked perfectly fine (and fast!) for me for all purposes, so I haven't had a need for Xen. However, I'm using qemu on FreeBSD with the kqemu module. As far as I know, that module doesn't work on DragonFly, unfortunately. Well, at least DragonFly can run _inside_ qemu without problems. :-) Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
