Do you have any messages from dom0 (xl dmesg, /var/log/xen/... ) that
could help please ?
First, thanks for helping, nothing really stood out in the logs for me
but I've pasted them below anyway.
The (build domU) system also feels slightly slower than netbsd-7, but
I could well be imagning that.
So what's going on here?
Hard to tell without more data. All you've given us is a process fork
related domU hang which isn't much to go on.
Would you be able to break into ddb, for eg: and give us a dmesg, ps and
other info ?
I built a kernel with DEBUG and LOCKDEBUG and breaking into ddb works.
I'll keep the machine in ddb if you have a more specific suggestion.
