True, I'm sorry, too few informations.

The host system is Slackware64 Linux 13.37
QEMU emulator version 0.14.0 (qemu-kvm-0.14.0), Copyright (c) 2003-2008 
Fabrice Bellard
FreeBSD 8.2-RELEASE-p3

kvm option: /usr/bin/qemu-system-x86_64 -pidfile $PIDFILE -cpu host -smp 
$NCPU -m $MRAM -k $KB -enable-kvm -drive 
file=$IMAGE,media=disk,index=0,cache=writeback -net 
nic,model=$NICMODEL,macaddr=$MAC -net 
tap,ifname=$TAP,script=no,downscript=no -runas $USER -monitor 
unix:$SOCKET,server,nowait -nographic -daemonize

There are not errors. When there is the countdown  it seems to die.For 
example it stops to 9 seconds or 6 and stop (die) No boot line, only the 
boot loader menu blocked. To avoid this
I want say that freebsd work very well under kvm, the problem is 
presented every 2/3 startup of this virtual machine.
