I jeszcze to:

FreeBSD host notes:
- expect timer problems when guest kernel HZ is > hosts,
for example time sleep 1 takes 49 seconds and booting sleeps for
minutes at the acd0 probe with a FreeSBIE 1.0 guest, thats because
its kernel is built with HZ=5000, and FreeBSD's default is 100...
(no longer a problem with FreeSBIE 1.1.)  The linux 2.6 kernel uses
1000 by default btw.  Enabling /dev/rtc doesn't seem to help either
(not included since it needs a patch to emulators/rtc.)
- RELENG_6 and up guests often crash while accessing the emulated cdrom
(see kern/84102, http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/84102),
using a kernel without PREEMPTION has been reported to fix this problem.
(or do an ftp install instead of installing from the emulated cdrom, and
then make a new kernel.)  [fixed since 6.0-R.]
