Because libvirt_lxc create a thread to mount fuse filesystem. and then libvirt_lxc will try to access the fuse filesystem.
Without waiting,libvirt_lxc may access fuse before it is mounted.
And I can't find a better way to make accessing fuse after the fuse being mounted,because fuse_main will return until fuse being unmounted,so I don't know how to pass message to tell libvirt_lxc whether the fuse is mounted success.
Oh I see. This is solvable, but I believe that you cannot use fuse_main. You have to look at the fuse sources (quite complex!) and do the individual fuse operations.
Have a look at how libguestfs does it ...

Thanks for the information. Can fuse_mount & fuse_new & fuse_loop avoid the waiting? It seems has the same problem. Thanks Gao
