Hi,

Is it possible to freeze a zone and unfreeze it a few seconds later?


that:


$2}'`
 kill -s SIGSTOP $running_processes
 ... do important stuff here...
 kill -s SIGCONT $running_processes

I can't find anything like that in the doc. In the mean time, I've done running_processes=`ps -o s= -o pid= -z $zone_name | grep -v T | awk '{print

You could probably use a dtrace script along the lines of the
following in the global zone...

# dtrace -wqn 'sched:::on-cpu /zonename == $1/ { printf("Stopping pid
%d/%d in %s\n", pid, tid, zonename); stop(); }' $zone

When you are ready to unfreeze it:

# prun `pgrep -z $zone`

thanks, it could probably enhance things a bit
