When I use the command 'virsh save' to save the domain state,
I receive the following error message:
operation failed: Migration unexpectedly failed.
I debug the qemu by adding some printf(), and find the function
pclose() returns -1.
I use strace to trace qemu, the log is as the following:
======
close(17) = 0
--- SIGCHLD (Child exited) @ 0 (0) ---
wait4(-1, NULL, WNOHANG, NULL) = 22016
rt_sigreturn(0) = 0
wait4(22016, 0x7fff7f1034fc, 0, NULL) = -1 ECHILD (No child
processes)
======
We wait the child twice: one is in signal SIGCHLD handling and the
other
one is in pclose().
We should disable sigcld handling before calling pclose().

Ping :)
Ping Again... :)
os-posix.c part looks sane to me, but what about Win32? Wouldn't it
need stub functions?
