[Libguestfs] libguestfs binaries missing when built from source code

[emlyn.jose at wipro.com]

Hello Richard!

Another problem came up today while working on it:

[INFO] >>> Resizing qcow image...
[INFO] >>> Executing: cp AirFrameVirtualized-3.0.76999.qcow2 image.tmp
[INFO] >>> Executing: qemu-img resize -f qcow2 AirFrameVirtualized-3.0.76999.qcow2 10G
Image resized.
[INFO] >>> Executing: virt-resize --expand /dev/sda1 image.tmp AirFrameVirtualized-3.0.76999.qcow2
[   0.0] Examining image.tmp
libguestfs: trace: set_verbose true
libguestfs: trace: set_verbose = 0
libguestfs: trace: set_path "/opt/libguestfs/x86_64/1.30.3/lib/guestfs/appliance:"
libguestfs: trace: set_path = 0
libguestfs: create: flags = 0, handle = 0xfa6c90
virt-resize: symbol lookup error: virt-resize: undefined symbol: guestfs_int_safe_malloc

When I browsed on it, I found that it is because of the older OCaml bindings. Is it so? Is it related to ocaml?

Below are the build dependencies of ocaml used while building libguestfs:

ocaml                 x86_64 3.11.2-2.el6          rhel6-optional
ocaml-findlib         x86_64 1.2.5-5.el6           rhel6-optional
ocaml-runtime         x86_64 3.11.2-2.el6          rhel6-optional

Regards,
Emlyn Jose.

Those particular files are the OCaml bindings.  They are only needed if you intend to write a brand new program in OCaml using guestfs (https://clicktime.symantec.com/a/1/LLuCVR5AtuWHONgYvylpSI5rBvmm8Jk2842YsgrbHBk=?d=0Hg85it0VOduhj2huLZ_4yqwG0IC1HZft_Xht0zT7qE1QRbto_bXJNtsjTe-_HG91qnxSTcXDNsMIvmCg4U8B6TIZZPkmCxZhdkv-V2HAqgAdNKsbW1ToYm_gBevDJOrAF7-cJ4V537BvZo5_SWzCYlGrVyZUg2Gc0YtEBFUxUURl6IkvYavCIEB_nC-3Djd5SHg8IZ9rcnyjVVIeWOJjxgAsR3qqlbBaXBG1Xes7IaotVasihjIDbDDJ1TryRYf94njYLryKeZI3AQjiz3Uv8cWDu1wK1wAjtP1k_T-6e1HohevLFBM907zFtw3uwVdLCaU2L5Nxw0WcDk7IFAoz4UV4seG2ahSQAxmtGQk99s5rZPz_C2ayd7GHeWjPWHFKEoH7w%3D%3D&u=http%3A%2F%2Flibguestfs.org%2Fguestfs-ocaml.3.html).  Otherwise you can remove them without any ill effect.

However I'm surprised that whatever spec file you are using doesn't find and package those files into two ocaml-libguestfs* subpackages.

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