Status of libguestfs in Fedora, RHEL
by Richard W.M. Jones
Just a note (mainly to get it clear for *me*!) where we are with
libguestfs branches and Fedora/RHEL versions:
Fedora
│
├── Fedora 16 libguestfs 1.16 (currently 1.16.29)
│
├── Fedora 17 libguestfs 1.18 (currently 1.18.6)
│
├── Fedora 18 (just libguestfs 1.19.28, will move to
│ branched) stable 1.20 branch when it is ready
│
└── Rawhide follows development releases as usual
Unfortunately a combination of factors make testing releases in Fedora
18+ impossible right now:
- NTFS breakage with the new kernel (http://bugzilla.redhat.com/844485)
- DWARF symbols are broken, making it challenging to run any valgrind
tests
The unfortunate result is that Fedora 18+ releases aren't tested to
our usual high standards.
RHEL
│
├── RHEL 5 ancient libguestfs 1.2
│ │ (DO NOT USE this version except with virt-v2v,
│ │ and even then it's far better to use RHEL 6)
│ │
│ └── EPEL 5 libguestfs 1.19 from oldlinux branch, will
│ move to 1.20 when it is ready
│
│
├── RHEL 6
│ │
│ ├── RHEL 6.0 libguestfs 1.2 (no longer supported, DO NOT USE)
│ │
│ ├── RHEL 6.1 libguestfs 1.7.17 (no longer supported)
│ │
│ ├── RHEL 6.2 libguestfs 1.7.17 (no longer supported)
│ │
│ ├── RHEL 6.3 libguestfs 1.16.19 + RHEL patches
│ │
│ ├── RHEL 6.4 rebase along libguestfs 1.16 stable branch
│ │
│ └── RHEL 6.5 unknown, possibly rebase to 1.20 if
│ there is time and any demand for it
│
│
└── RHEL 7 intending to go with libguestfs 1.20

The library hasn't been ported to Windows at this time.
Thing may improve once we add libvirt remote support in the near
future -- you would be able to access a remote hypervisor managed by
libvirt, using libguestfs + libvirt as client libraries on Windows.
But even this will still require that the library part of libguestfs
is ported to use Windows, so that will still be a fair bit of work.

virt-top is 'top' for virtual machines. Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.

What does virt-inspector2 [this is RHEL 6] display for this guest?
virt-inspector2 -d guest
virt-ls fundamentally doesn't work with multi-boot guests. However
that doesn't mean to say you can't use libguestfs, you just need to
use some lower level tools or write a Perl/Python/whatever script
against the API. Have a look at the second example in the
guestfs-perl(3) / guestfs-python(3) man pages to give you some ideas
how to go about this.
By the way it's probably better to use the RHEL 6.3 package,
libguestfs 1.16.19, since it has more bugs fixed.

If I understand your question correctly, then the 'mountpoints'
command lists what is mounted, eg:
$ guestfish -c qemu:///system -d F16x64 -i --ro
Welcome to guestfish, the libguestfs filesystem interactive shell for
editing virtual machine filesystems.
Type: 'help' for help on commands
'man' to read the manual
'quit' to quit the shell
Operating system: Fedora release 16 (Verne)
/dev/mapper/vg_f16x64-lv_root mounted on /
/dev/vda2 mounted on /boot
><fs> mountpoints
/dev/vg_f16x64/lv_root: /
/dev/vda2: /boot
(or 'mounts' which does the same but only lists the devices).
Please send replies to the mailing list. I hopefully deleted any
specifics of your environment in this reply.
