Xen timeline for 6.x
Hi all, I've been wondering about the status of Xen support and its possible inclusion in the 6.x branch. Originally it was mentioned in the FreeBSD status reports that full (domU and dom0) Xen support for the FreeBSD kernel would be merged in before 6.1-RELEASE. But I have also read on fsmware.com that there were problems in integrating some subsystems which could delay these plans. It looks like it's now too late to still introduce this before 6.1-RELEASE. Is there an updated timeline known about Xen in the 6.x tree? Kind regards, walter -- My eyes! The goggles!

Kernel forces machdep.hlt_cpus, how to change?
Hello all, I'm testing out FreeBSD 6.0R on a Dual Xeon. I want to do some benchmarking of hyperthreading before I put this machine into use, so I am trying to turn off the HLTing of logical cpu's. A stock "SMP" kernel without any options gives the following sysctl's on this machine: machdep.hlt_cpus: 10 machdep.hlt_logical_cpus: 0 machdep.logical_cpus_mask: 10 So even though I have hlt_logical_cpus at 0, the kernel seems to have decided to HLT my cpu's 8 and 2, the 'logical' threads on each Xeon I assume. I've tried to get around this by setting the following: test# cat /boot/loader.conf machdep.hlt_cpus=0 machdep.hlt_logical_cpus=0 But still after booting I get the same result with the cpu's HLTed. I'm not sure if using them for user processes actually helps, but I'd like to experiment with the setting. Any ideas how I should accomplish this? Cheers!

We are using a simple shell script that can be placed in
/usr/local/etc/rc.d/bootreport.sh. It sends out an email to
root with the dmesg output, and also sends an email when the
system is being shut down.
#!/bin/sh
HOSTNAME=`/bin/hostname`;
case "$1" in
start)
(echo $HOSTNAME was booted at `/bin/date` ; echo ''; echo '--';
echo ''; echo 'dmesg output:' ; /sbin/dmesg) | mail -s "$HOSTNAME boot" root
;;
stop)
echo $HOSTNAME was shut down on user request at `/bin/date` |
mail -s "$HOSTNAME shutdown" root
;;
*)
echo ""
echo "Usage: `basename $0` { start | stop }"
echo ""
exit 64
;;
