Second round of patches. These work so far that you can get directory listings and stuff like that ... Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones libguestfs lets you edit virtual machines.

This is the third version of the FUSE bindings for libguestfs. Still, read and write calls don't work, but you can now navigate through the filesystem hierarchy efficiently. Rich. .gitignore | 3 + HACKING | 3 + Makefile.am | 5 + README | 2 + TODO | 37 +-- bindtests | 13 + bootstrap | 2 +

It is never normally valid to use the mount-local* APIs when you haven't mounted some filesystems in the libguestfs namespace. If you try it, it results in some odd errors. The mount-local-run call is successful, but subsequent operations fail: $ mkdir -p /tmp/mnt $ guestfish -x -N fs mount-local /tmp/mnt : mount-local-run libguestfs: error: lstat: lstat_stub: you must call 'mount'

Hello, Can anyone please tell me whether guestfish can mount exFAT partitions? I created a full disk image of a drive which contained a single exFAT partition. Was able to mount it with kpartx/FUSE: # kpartx -a -v disk.img add map loop0p1 (252:2): 0 39070078 linear 7:0 2 # mount /dev/mapper/loop0p1 /mnt -o ro FUSE exfat 1.2.3 # ls /mnt foo bar baz etc but not guestfish: $ sudo apt install

The architecture of

Upon seeing RWM Jones article "Using mount-local API from C" I became curious because I thought there WAS a way to combine aspects of FUSE with the tools provided by libguestfs. So if I wanted to create my own filesystem using callbacks placed in the 'fuse_operations' struct (parameter to 'fuse_main()'), I could do so using guestfs. But after reading the article and

OK, subject says using guestmount. I'm surprised the slowdown isn't more than 95%. It's using FUSE which goes through an insane number of layers,

* PATCH FOR DISCUSSION ONLY - NOT TO BE APPLIED * Colin suggested something which seems eminently sensible: https://bugzilla.redhat.com/show_bug.cgi?id=916780 I've been through a couple of rounds of trying to implement this. I started with adding the option as suggested to the guestmount program, but it tended to make the guestmount program more complex. More importantly, adding the option
