Hello,
I launched guestfsd in my guest with this command : guestfsd* -rv*.
When i close the handle the deamon crashes.
This is the output i got (Deamon side) :
guestfsd: main_loop : new request, len 0x28
fsync /dev/sda
/dev/sr0 : No medium found
guestfsd : main_loop : proc 282

*read: unexpected end of file on fd 3 *
I got the same error with both ubuntu12.04 and fedora 20 guests. I know
that in ubuntu the guestfsd version is quite but fedora 20 has 1.26
libguestfs version i think.
Can you attach a debugger to it and find out where it crashes or
exits. Something like:
# gdb /usr/sbin/guestfsd `pidof guestfsd`
(gdb) break exit
(gdb) cont
... when it exits ...
(gdb) bt
As discussed on IRC, guestfsd is single-threaded at the moment, but
one of the jobs for 1.28 is to add support for multiple parallel
connections.
