Hi I`ve been trying this guestfs_mount_local api for quite a few days, but still can`t get over it. Now it seems to have enter the fuse loop but have some problems with 'mount'? and stops at guestfs_mount_local_run(g). Here`s corresponding code in the test program: ?? if(guestfs_mount_local(g,"/mnt/libg")==-1) exit(EXIT_FA...

Recently i deployed latest 1.17.40 on rhel6.1. When i ran a tiny program which was to test the function guestfs_mount_local() or those similar functions that mounts locally, Error prompted?undefined symbol guest_mount_local ! Why didn`t this undefined symbol error prompt when the program was first compiled,but occurred when it was run? Then i gave guestfish mount local a try in the shell, and found that ok.I thought it...

Hi, I have tried to extract *.vhd* file using guestfs library. I am able to list all files inside my archive using *guestfs_ls* also * guestfs_list_filesystems()* retruns right File system information. I am trying to extract files from inside archive using *guestfs_copy_device_to_file() * but it returns following error (error: copy_device_to_file: unknown option 689330304 (this can happen if a

[These two patches are for discussion only] Allow FUSE support to be used directly through the API. This is the second commit. In order to make this usable from guestfish, we have to also bind the events API in guestfish. This is the first commit. Rich.

This changes the proposed API slightly. Previously 'mount-local' generating a 'mounted' event when the filesystem was ready, and from the 'mounted' event you had to effectively do a fork. Now, 'mount-local' just initializes the mountpoint and you have to call 'mount-local-run' to enter the FUSE main loop. Between these calls you can do a fork or whatever

The existing mechanism was clunky, slow and used ~ 10 MB of local disk. Rich.

This patch is just for review. It enables FUSE support in the API via two new calls, 'guestfs_mount_local' and 'guestfs_umount_local'. FUSE turns out to be very easy to deadlock (necessitating that the machine be rebooted). Running the test from the third patch is usually an effective way to demonstrate this. However I have not yet managed to produce a simple reproducer that can be repor...

This version doesn't crash or cause hung processes or stuck mountpoints, so that's an improvement. Rich.

Split up the huge generator/actions.ml into several smaller files. Rich.
