One quite practical process migration mechanism is bproc:
http://www.clustermatic.org
and just at this moment I am debugging it (cause I want working pty)
using quite standard linux tools (and bproc itself):
strace -f -p pid ... spy on syscalls used by process pid
bpsh 1 strace -f -p pid ... same on slave node (I spy on sshd)
printk() ... print message from kernel
klogd ... resend kernel messages to syslogd
syslogd on slave ... send messages to master syslogd via IP
syslogd on master ... log messages to file
less (press F) ... show messages to me
Another viable process migration mechanism is MOSIX, but I didn't
update my MOSIX knowledge for years now.
