Description Richard W.M. Jones 2009-08-22 05:28:04 EDT
Created attachment 358299 [details]

(Reported by Chunyang Liu)

After calling guestfs_close from the test program attached, the
qemu process remains in the defunct state until the main program

26100 pts/1    Z+     0:21 [qemu] <defunct>

Apparently we are missing a wait() somewhere.

Reported and verified on EPEL 5.3.

$ gcc -Wall -o test test.c -lguestfs
$ ./test 
Handle closed - now run 'ps ax' to see if qemu process is defunct

[in another window]
$ ps ax | grep qemu
26280 pts/2    Z+     0:20 [qemu] <defunct>
