Hey Rich, In the past I know you have mentioned that using guestfs.kill_subprocess() isn't strictly necessary after you are finished using libguestfs. I believe you said that in the python bindings, that step would happen automatically when the object goes out of scope and the __del__ method is called. However, since it never seemed to harm anything and I wanted to be extra...

...hich uses libquestfs. I am simulating a small cloud and have some apps that need to talk to the guests. All works really well until I needed to start another process. So I start a process then "oz" starts up a VM (it uses libquestfs) then when "oz" cleans up it calls libquestfs.kill_subprocess(). At this point my test locks up. A bacetrace of the python code is: #0 0x00000036fe80ef1e in waitpid () from /lib64/libpthread.so.0 #1 0x0000003629c0df7f in guestfs_close () from /usr/lib64/libguestfs.so.0 then a mess of python stuff If I attach to it with strace it shows: wait4(0, It looks...

This is an alternative approach to https://listman.redhat.com/archives/libguestfs/2023-January/030535.html After discussing this with Dan Berrange we came to the conclusion that you really might want to set LISTEN_FDNAMES to arbitrary short strings (or not set it). Especially when talking to qemu-storage-daemon which would allow you to use these names on the command line. Rich.

https://bugzilla.redhat.com/show_bug.cgi?id=836710 https://bugzilla.redhat.com/show_bug.cgi?id=836913 There are at least two related bugs going on: (1) Linux sync(2) system call doesn't send a write barrier to the disk, so in effect it doesn't force the hard disk to flush its cache. libguestfs used sync(2) to force changes to disk. We didn't expect that qemu was caching anything
