iSCSI initiator iqn
by Raghu 06 Jul '14

06 Jul '14

Hi, I could not find any option to set iSCSI initiator iqn while using guestfish, although the underlying qemu command has this option. It appears that each time guestfish tries to connect to iSCSI LUN, a randomly generated initiator iqn is being used. This is preventing guestfish to connect to the iSCSI target in our environment as the target allows incoming connection based on the preconfigured initiator iqn. Is there way to set iSCSI initiator iqn with guestfish command? Regards Raghu

Now you should try actually resizing the partition in virt-rescue. Since it is inside ``virt-rescue --ro'' it won't actually alter the disk image -- the ``--ro'' flag means that libguestfs puts a protective overlay between the commands in the rescue shell and the underlying disk image.

[PATCH] generator: Sort the structs.
by Richard W.M. Jones 01 Jul '14

01 Jul '14

Sort the structs when generating code. Since the structs are logically indepedent of each other, this should have no effect except to make generated files list the structs in a different order. However this also fixes the following build problem: File "convert_linux.ml", line 322, characters 43-50: Error: This expression has type G.stat = Guestfs.stat but an expression was expected of type G.dirent = Guestfs.dirent It turns out the OCaml bindings don't like the fact that we have two structs with a common field name (dirent.ino and stat.ino). In OCaml < 4.01, this means that any attempt to reference stat.ino would fail because dirent.ino appears second in the file, overriding stat.ino. In OCaml >= 4.01 the compiler now uses some disambiguation rules based on the known types to resolve this problem.
