Hell Michal,
Thank you for your answer, but this doesn't fix my problem.
Run your fixed script and we get the same behavior:
$ perl test-chldhandle-bug-fixed.pl
init... pid=29713
while...
fork 1
end... pid=29716
receive chld
fork 2
end... pid=29717
receive chld

go next...
I'm not a perl expert, but I don't think it's a libvirt bug anyhow.
Moreover, I don't see any zombies:
$ perl test-chldhandle-bug-fixed.pl & sleep 5 && echo && ps axf | grep
perl && echo
[1] 11239
init... pid=11239
while...
fork 1
end... pid=11241
receive chld
fork 2
end... pid=11242
receive chld
connection open
11239 pts/18 S 0:00 | \_ perl test-chldhandle-bug-fixed.pl
11245 pts/18 S+ 0:00 | \_ grep --colour=auto perl
fork 3
end... pid=11246
receive chld
fork 4
end... pid=11247
receive chld
go next...
btw: with older version I'm seeing this:
11399 pts/18 S 0:00 | \_ perl test-chldhandle-bug.pl
11401 pts/18 Z 0:00 | | \_ [perl] <defunct>
11402 pts/18 Z 0:00 | | \_ [perl] <defunct>
11405 pts/18 S+ 0:00 | \_ grep --colour=auto perl
What zombies are you seeing? Perl ones or libvirt or ..,?
