Hi, Mr. Rich. I am sorry that I left too little information in the last email because I edited with my mobile phone. I wrote about my first question in the following link. https://rwmj.wordpress.com/2010/11/15/libguestfs-inspection-now-lists-windows-apps/ 2nd. Question After I call the mount_local() function in guestfs.py to operate on a disk, I hope to umount it. After calling the umount_local() function, the program hangs in the foreground and no log is displayed after that. At the same time, _check_not_closed() did not throw an exception. I'm looking forward for your reply. Thanks, y...

They all seem to rely on mount.cifs and you need to be root to run this. When

...fuse support is limited. Only the '-o' FUSE options can be passed and "only some of them are a good idea". So how would one use guestfs with a filesystem "made" with Fuse? For example - using Jones module 'https://github.com/libguestfs/libguestfs/blob/master/examples/mount_local.c' could I combine it with the Fuse defined filesystem detailed in the BBFS tutorial (http://www.cs.nmsu.edu/~pfeiffer/fuse-tutorial/)? Or would that be a futile effort?

...k feature availability before using it. Moreover a lot of functionality of libguestfs very depends on a host kernel and available modules. My experience with libguestfs forces me to build it myself. I also build my custom guestfs appliance to not depend on a host kernel etc. You can consider using mount_local but that is another story... -- Mykola Ivanets

Hi All, In the last few days, I've been working on leveraging a pluggable mechanism that is going to be introduced for muCommander [1] to provide a front-end for libguestfs. I published a video [2] that demonstrates this integration: enabling to browse/upload-to/download-from virtual disks via a file manager with a dual-pane interface. I've followed the guidelines for inspecting the

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
