ok so i've a few more info. my host system has 4 cpu (centos-5.1 x86_64) and if give 4 vcpu to the guest (centos-5.1 i386) it's working correctly IF i do _not_ start any other guest on the host. if i start other guests, then it's randomly start or not start a given command. but with taskset -c 0 it's always runs the command. now i switch back to 1 vcpu since i can't force vcpu (taskset) for cron tasks and other processes:-( -- Levente "Si vis pacem para bellum!" ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
